A Road Trip to Route ... Zero

Published by AC Business Media

201 N. Main Street, 5th Fl., Fort Atkinson, WI 53538 (800) 538-5544 •


n only over a year after the Global Cement and Concrete Association (GCCA) put forth a goal to achieve carbon neutrality of the worldwide cement and concrete industry, the Portland Cement Association (PCA) has provided a path forward. Released on Oct. 12, their "Roadmap to Carbon Neutrality," is an ambitious journey to carbon JONATHAN KOZLOWSKI, EDITOR neutrality across the cement and concrete value chain. JKOZLOWSKI@ ACBUSINESSMEDIA.COM The announcement explains that the PCA Roadmap outlines a portfolio of reduction strategies and immediate opportunities across the various phases of the built environment: production at the cement plant, construction including designing and building, and everyday infrastructure in use. Across this full cement-concrete-construction value chain, the Roadmap recognizes five main areas of opportunity: clinker, cement, concrete, construction and carbonation (using concrete as a carbon sink). Each phase of the value chain is integral to reaching the goal and can unlock unique and specific pathways to carbon neutrality, including actions such as reducing CO2 from the manufacturing process, decreasing combustion emissions by changing Adobe Stock Images | By Nuttapon fuel sources and shifting toward increased use of renewable electricity. Many of the solutions included in the PCA Roadmap are products, technologies and approaches that exist today—and by bringing together a variety of collaborators, PCA intends to ensure the adoption of these solutions on a broad scale. Utilizing products like the types of cement that produce fewer carbon emissions such as portland limestone cement and the integration of carbon capture systems at the cement plant will all make a difference. As Albert Manifold, GCCA president, said during the GCCA's roadmap announcement, "Just as society needs concrete, concrete needs society." (Such a great line.) So, join us in this caravan on our road trip down Route Zero as we take this journey together. Remember, don’t fold the map. As always, stay safe out there.

Moisture Test On The Spot


hile traditional laboratory and online-based moisture measurement techniques are useful in the right settings, they have lacked the simplicity and flexibility required for frequent spot checks on construction sites. Industry innovators have developed a simplified approach with testing equipment that allows anyone in the field to get laboratory-quality measurements in any environment. Using a hand-held device such as the HI520-2 concrete and mortar moisture meter by Kett, the worker would select the calibration (i.e., concrete or mortar), press it against the sample, and moisture is immediately displayed with an accuracy of +/-0.5% (0-12% for concrete/0-15% for mortar). Automatic

temperature compensation enhances measurement accuracy, and two “raw” modes allow the user to calibrate for deep or shallow samples. One construction contractor used the moisture meter to confirm that the concrete flooring on a 20-story building was ready for custom surface treatment. In fact, this contractor was able to test the entire project in one morning. Installers can test concrete humidity as water passes through the concrete’s surface even after it hardens. This kind of testing is critical in indoor installations, where high levels of moisture and trapped water in concrete can create mold or lead to bubbling or degradation of its strength and integrity—particularly helpful for concrete subflooring.

If you are building on a slab, you know the importance of a concrete subfloor that is fully dried and accurately prepared for use. Knowing how the concrete will act when the it is coated, flooring installed, or prepared for final use is key to success. For those who need more specialized applications of measuring moisture, such as for “wet” concrete, this is also available with other units. With those, the sample moisture of slurry and aggregate can be instantly measured and batch mixes can be optimized. Del Williams is a technical writer.

MAX USA's TwinTier RB611T Large Jaw Cordless Rebar Tying Tool

Faster tying speed 4,000 ties per charge • Reduction in wire consumption • Uses a shorter wire tie, requiring less concrete to cover Capable of tying from #5 on #5 to #9 on #10 rebar, the RB611T TwinTier is a battery-powered rebar tying tool capable of tying the largest-sized rebar. The TwinTier platform ties at approximately 1/2 second per tie due to its dual wire feeding mechanism. This tool platform also uses less wire per tie because of the wire pull-back mechanism (yields approx. 200 ties per spool when tying #5 on #5). These efficiencies make the RB611Ts very appealing, especially to contractors who have previously used older rebar tying tools. Each tie is equivalent to a 16 ga. hand snap tie and the fast-tying speed is especially useful for contractors facing a shortage of labor in some areas of the country. • •

While many excellent technologies delay and mitigate the effects of corrosion on embedded reinforcement, there are fewer options when corrosion takes place deep inside concrete. Cortec's MCI-2020 Gel was designed to penetrate to the heart of a structure’s corrosion problem.

Form-A-Tube Form Building System

Form-A-Tube, developed by Centennial Professor of Civil Engineering at the University of Arizona, Mo Ehsani, PhD, PE, SE., allows contractors to instantly construct forms for shoring up pilings with cement. The system builds forms of any size on site, making it easy to use even in remote locations. "This stuff is so modular you can take it down into 6 1/2-in. strips, and put it together on site," says Harvey Sharp, whose company BCG Services is handling a water pumping station in Houma, La. "It's second to none." He found Form-A-Tube to be effective, economical, and fast. "It takes a quarter of the time that it would take to do a regular bridge repair," he says, who added that his clients love it. "If you had to remove the pilings, it would take months. Not only did Form-A-Tube save time, but saved the client's money." Each Form-A-Tube piece has unique ribbing that can be placed inside the form and left in place, creating an attractive and almost impermeable outer shell. The tube can be placed on the outside so once the concrete filling has hardened, the pieces can be removed—and reused.

MCI-2020 Gel is an injectable corrosion inhibitor that provides a robust dose of corrosion protection directly at or near the depth of steel reinforcement in concrete. MCI-2020 Gel utilizes the chemistry of Cortec’s Migrating Corrosion Inhibitor (MCI) Technology to migrate to steel reinforcement from injection locations. Once at the reinforcing steel, MCI molecules deposit across the metal surface to form a molecular layer which acts as a barrier to corrosive elements such as chlorides.

Cortec's CorrVerter MCI Rust Primer

Without the need for abrasive, water blasting, and intensive labor, CorrVerter MCI is a unique formulation of chelating agents combined with a high solids waterborne latex with extremely low water vapor permeability. This fast-drying, singlecomponent primer converts surface rust into a hydrophobic passive layer and offers excellent protection against re-rusting of metal surfaces. Reinforcement coated with CorrVerter MCI Rust Primer has similar bond strength to concrete compared with uncoated rebar. CorrVerter MCI Primer offers engineers, owners, contractors, DOTs, and government agencies a convenient, low-labor option when performing repairs on heavily corroded rebar and other metal surfaces. It converts rust quickly and provides ongoing protection without compromising bond strength. Contractors may rely on it as an integral part of a highperformance repair system that extends the service life of concrete structures.

Used only in solid concrete and should never be installed in any other type of masonry material. Never install the CONFAST Strike anchor in ACQ treated lumber. Designed to be used where consistent embedment and protrusion above the surface is critical. Visually inspectable due to the positive drive and positive setting of the anchor. Available in six diameters of 1/4 in., 5/16 in., 3/8 in., 1/2 in., 5/8 in., 3/4 in. and a wide variety of lengths that will meet most application requirements. Each box of anchors comes packaged with nuts and washers. The length of the anchor is measured as an overall length with the body of the anchor being threaded for a portion of its length.

ACI Reinforced Concrete Design Handbook The American Concrete Institute has released the new ACI Reinforced Concrete Design Handbook as a threevolume handbook providing guidance to professionals engaged in the design of reinforced concrete structures. The ACI Reinforced Concrete Design Handbook is available in print, as a digital download, and as part of the new ACI 318 PLUS subscription. The ACI Reinforced Concrete Design Handbook is published in three volumes: the first volume covers introductory chapters, structural analysis, durability, and member design. More specialized topics including retaining walls, serviceability, the strut-and-tie method, and anchoring to concrete in chapters 12 through 15 are published in the second volume. A third volume containing design aids and a moment interaction diagram Excel spreadsheet are available as free downloads.

Of Rebar, Corrosion & Prevention


early 40% of failure of concrete structures occurs due to corrosion of embedded steel reinforcement. There are numerous causes but most often it is related to environment, quality of concrete, and quality of construction practices. Among the commercial technologies available, migrating corrosion inhibitors (MCIs) show versatility as admixtures, surface treatments, and in rehabilitation programs. Organic inhibitors use compounds that work by forming a monomolecular film between the metal and the water— one end of the molecule is hydrophilic and the other hydrophobic. MCIs can be incorporated as an admixture at the plant or into the ready-mix truck, surface impregnation of existing concrete structures, or coated rebar cast

in concrete. The inhibitor migrates through the concrete capillary structure, first by liquid diffusion via the moisture that is normally present in concrete, then by its high vapor pressure, and finally by following hairlines and microcracks. The diffusion process requires time to reach the rebar’s surface and to form a protective layer. With surface impregnation, diffusion transports the migrating corrosion inhibitors into the deeper concrete layers—even in the presence of chlorides. Results of one study showed that the products successfully inhibited corrosion of the rebar in a 3.5% NaCl solution for the duration of testing; protected samples showed an average corrosion rate of 0.4 µA/cm2 (compared to untreated samples 5.10 µA/cm2). According to this data, using

MCIs can have the potential to increase the life expectancy of a concrete reinforced structure by more than 40 years. By using MCIs, structures should have a stronger resistance to corrosion and therefore possess greater durability. Such increased durability would then mean fewer repairs, greater structural integrity, and longer service life—all leading to greater sustainability. In order to earn certain LEED credits, ensure that the MCI you want to use is made from a renewable raw material.

Propane & Propane Benefits


teve Dodson, service manager at Refuse Materials Inc., a contractor based in Ocilla, Ga., started the switch to propane about 10 years ago. It seems the concept has began to gain traction with more companies in the concrete industry, with a noticeable shift over the past five years. Propane is a highly portable energy source, allowing contractors to complete work without bringing in an alternative power source for electrical equipment. Propane’s grid independence is especially beneficial for jobsites that aren’t yet connected to utilities or are located off the grid entirely. It also eliminates restrictions and safety hazards brought on by electric cords. The ease of operation that comes with propane equipment is critical.

“Time is money in the construction world,” says Dodson. It’s a huge reason his crew of commercial flooring contractors prefers operating propane equipment. “Electric [can be] binding between the length of power cords to having to wait on an electrician to drop power into our work area,” he says. “Any time we have guys standing around waiting on someone else, it’s costing us a lot of money. Propane makes it easy for our team to get mobilized and start work immediately when they step onto a jobsite.” WORK INDOORS Using clean, low-emissions equipment is important for crews working on jobsites located in areas with strict emissions regulations or in residential areas

concerned with air quality. According to Brian Delehaut, vice president at MK Diamond Products, one reason customers find value in having propane engines in their fleet by providing a green soltuion. Deemed an approved clean alternative fuel by the Clean Air Act, propane produces significantly fewer emissions compared with other options, enabling it to be used indoors (with proper ventilation). Matt McDonald is the director of off-road business development for the Propane Education & Research Council.

The Sound of Silence


ound is an important, yet often overlooked, part of our daily lives. Its effects on health have become an important part of the safety conversation, the negative effects of sound exposure on employees and the public are a growing concern with construction and demolition key among industries. Finding efficient, cost-effective ways to limit sound pollution has become a major priority for contractors. But sound-proofing an active jobsite is easier said than done. So, contractors have begun looking to innovative manufacturers for creative equipment solutions to stem the noise. Handheld pneumatic devices and concrete saws operating as part of a road or bridge repair project register around 100 dB. Hydrodemolition robots, on the other hand, typically operate about 10 dB lower. The quieter operation is thanks in part to a heavy rubber hood over the demolition area that helps protect workers from flying debris but also dampens sound. Remote operation increases sound safety by keeping workers at a distance. Diesel-powered, trailer-mounted, high-pressure pump setups can be as loud or even louder than the robot. While hoarding (temporary solid barriers) works well, it takes extra time and resources to set up and often needs to be moved with the machinery, limiting productivity. Some of today’s innovative high-pressure pump designs solve this problem by incorporating hoarding into the equipment itself for a self-contained system designed to reduce decibel levels to almost the point of normal conversation. In addition to isolating engine sound within a container, some designs also employ advanced stop-start technology—similar to today’s automobiles. This method not only cuts down on noise levels, it reduces idling and can save as much as 20 to 25 liters of fuel per day. Noise restrictions will only continue to increase as jobsites move further into

heavily populated urban environments. Investing in quieter methods not only ensures contractors meet current regulations but promises long-term options as the construction and demolition landscape continues to evolve.

ake a look at almost any jobsite these days and you’ll likely see compact tool carriers (or CTCs). Productive equipment like CTCs make for a productive jobsite, so it’s essential to have a plan in place to keep them operating at peak performance. Here are five points in preventive maintenance CTCs. • Visual Inspection: Search for any signs of damage, noise, rattles or wear. Inspect the tracks or wheels, nuts, bolts, body, controls, guards, and any attachments. Look for any leaks around the hydraulic fittings, hose chaffi ng, and fuel hose. Check the battery for corrosion on the terminals or any loose or fraying wires. Check the tire pressure or track tension. Inspect the belts and replace any that show wear or cracks. • Maintain Fluid Levels: Most operators know to check the engine oil and coolant, but it’s also essential to be sure that hydraulic fluid levels are where they’re supposed to be. If the hydraulic fluid has a milky color, that’s a sign that there is water in the system—change the fluid (and fi lters) immediately.


CONC1021_28-37_Worksite.indd 36

• Clean Filters: Inspect and change the air fi lter on a regular basis. It consists of the canister, indicator, and main fi lter. Some systems are fitted with a service indicator mounted outside of the canister. The service indicator is the fi rst indication of the air fi lter condition. If the fi lter is restricted, the inside indicator will block the clear viewing window. Be sure to clean the outer prior to opening it to inspect or service the pre-fi lter or the main air fi lter. To meet recent EPA standards, many engine systems now have a carbon canister, which collects fumes from the fuel systems. Th is needs to be replaced every 200 hours or sooner if the canister becomes restricted with dust, dirt, or saturated with fuel. Hydraulic fi lters need to be replaced every 200 hours or if the hydraulic oil is contaminated. Use the OEM fi lter to assure the proper fit and meets the OEM specifications. • Lubricate Properly and Tighten Connections: Many problems occur simply because a part is loose. Performing a simple check with visual

inspection and touch the object to verify if loose or broken, tighten these with a wrench. Grease all pivot points and tighten all nuts and bolts before heading out into the field. • Safety Check: Make sure the parking brake is engaged (if applicable) and that the traction control lever is returned to neutral. Also, make sure that auxiliary hydraulics are disengaged, as many CTCs will not be able to start the engine if the traction control and/or the auxiliary hydraulics are not in the neutral position. Preventive maintenance isn’t a chore so much as an investment. A small amount of time spent caring for your CTC will save you the significant lost time, money, productivity, and the need to replace it less often. Dan Roberts is a Sr. Technical Service Representative for The Toro Company.

Robots in Demo: The Rise of the Machines BY JEFF KEELING


ithin demolition, remote-controlled machines provide an innovative mechanical solution, enabling contractors to continue moving forward despite ever-changing industry conditions. These machines also pave the way for new opportunities in industries such as processing, concrete cutting, mining, and tunneling. Here’s how. NON-STOP PRODUCTIVITY Th anks to advanced technology and a premier power to weight ratio, these compact machines can access some of the most restrictive jobsites—including those with dust, vibration, and noise restrictions as well as low floor loads. The most compact units are small enough to fit through standard doorways and light enough to be transported on passenger elevators, making them ideal for confi ned spaces and interior demolition projects. Regardless of size, these demolition robots provide an impressive hitting power, on par with excavators three times their size.

CONC1021_28-37_Worksite.indd 37

AN INCREASE IN SAFETY With an operating distance of up to 984 ft., remote-controlled units physically distance employees from harmful silica dust, as well as the strong vibrations of handheld equipment such as breakers, rivet busters, and chipping guns. . They can help prevent falls, one of the most common causes of serious work-related injury and death in construction. A remote-controlled unit allows operators to remain a safe distance from ledges and other fall hazards—providing peace of mind for workers and project managers. Climbing into or out of excavators or other compact equipment is a leading cause of jobsite injury, resulting in sprains, strains and other minor ailments. Eliminate this risk by allowing operators to remain safely on the ground and outside the immediate work zone. An advanced three-part arm and 360-degree rotation further reduces soft tissue and repetitive motion injuries. An ergonomic, lightweight control box conveniently attached at the waist also helps.

LABOR & SKILLED WORKERS At the heart of the labor shortage are two key factors—an aging group of current employees and fewer young workers. In addition to safety and comfort features allowing existing employees remain longer, cutting-edge robotic technology is attractive to younger workers. For one concrete cutting company, including advanced robotic technology in its fleet helped reduce the median age of their 300-strong workforce to 25, cut turnover 10%, and increased productivity 17% over three years. There’s no way to accurately predict what tomorrow’s jobsite will look like, but factors such as productivity, safety, and profitability remain evergreen. Mechanization allows companies to quickly adapt to changes in labor, process, or regulation, keeping them ahead of the curve—and the competition. Jeff Keeling is the North American sales and marketing manager for Brokk Inc.

Cortec's MCI-2062 Biological-Based Surface Cleaner

Cortec's MCI-2062 is another biological-based concrete surface cleaner similar to MCI-2061. Both MCI cleaners make use of the natural abilities of microorganisms to biodegrade their target waste substances effectively without the use of harsh acidic or alkaline products. However, where MCI-2061 focuses on the critical task of digesting hydrocarbon stains, MCI-2062 targets stains from organic wastes, proteins, fats, greases, and starches. It is therefore particularly suited to concrete heavily soiled by organic wastes in and around dumpsters, restrooms, and food processing facilities. MCI-2062 is a multipurpose concentrated bioenzymatic blend formulated for general cleaning on a variety of surfaces. It combines powerful cleaning chemistry with free enzymes and microorganisms capable of biodegrading a wide range of organic waste in order to leave facilities sparkling clean and odor-free. All the components work in synergy: cleaning agents lift and disperse the waste while enzymes work to speed up digestion by microorganisms. The microorganisms in MCI-2062 are preserved bacterial spores that remain inactive until MCI-2062 is applied. When MCI2062 is used according to instructions, the spores germinate into active microorganisms. Spores that remain in the substrate after rinsing continue to degrade residual organic waste constituents of stains that were not removed in the initial cleaning process. This allows MCI-2062 to be able to deep-clean porous surfaces like concrete and even carpet or other permeable substrates stained with organic waste.

Ameripolish SmartFloor Pad System

The SmartFloor concept is engineered to provide the end user with a highly aesthetic floor and an easy and economical way to maintain a polished concrete floor utilizing standard janitorial equipment and existing personnel.

MAX USA’s CP-W .133-in. Series Step Pin

Originally promoted for fastening applications surrounding steel I-beam construction, the CP-W .133-in. Step Pin has now been recognized and approved to fasten into a range of concrete types as well. The CP-W .133-in. pin has been widely adopted amongst contractors who moved away from powder actuated tools and have since utilize the HN120 from the PowerLite system, for fastening wood and metal track into steel I-beams. When the CP-W .133-in. pin was first introduced to the market, MAX had only obtained testing data for steel I-beam fastening as concrete fastening was already covered by the (CP-C Series Pin). MAX expanded the testing report for steel applications as well. Originally, the maximum thickness of steel I-beam testing data was 3/8-in., but the company conducted testing up to 1/2-in. thick steel I-beam and obtained an ICC report with the thicker material. “Because the CP-W pins are created out of a superior metal makeup (compared to CP-C Pins) the team decided to further expand testing to validate the stick rate for old and extremely dense concrete (up to 8,000 PSI concrete). The box quantity and model number for CP-W series pins were changed. The HN25C and HN120 are now available in 1,000 pins (originally 2,000).

The Core of Safety Tech


ccording to the National Safety Council, 105 million days were lost in 2019 due to workrelated injuries. While workers want to feel safe and physically confident on the job, this can be a challenge with core drilling. No matter how experienced a user is, the core drilling process is almost always dreaded. Rotary hammers and core drills can bind up when drilling through rebar or hard aggregate, causing the tool to rotate, and results in loss of control and potentially serious injuries—from broken wrists to wounds needing stitches. Safety Technology, such as seen in Milwaukee’s MX FUEL Core Drill AUTOSTOP technology helps protect workers. It reduces kickback during bind-up situations with engineered set

points to automatically stop running when thresholds are reached for a specific amount of time. AUTOSTOP systems contain an internal gyroscope that monitors angular momentum and uses onboard sensors to remove power from the motor before it rotates more than 45 degrees. At that engineered limit, the equipment will no longer fight the user. Safety Technology like AUTOSTOP along with the Core Drill’s side handle, helps address the risk of rotation, reducing the chances workers will be thrown off a ladder, lose teeth, break bones, etc. Inhaling crystalline silica dust particles can increase your risk of developing silica-related diseases such as lung cancer, chronic obstructive pulmonary disease, and kidney disease. Dust can be managed by either extracting it with

an extractor or by suppression using the onboard water connection. While elimination and substitution rank at the top of the NIOSH hierarchy, new solutions focused on Safety Technology are often some of the most impactful. Safety Technology is part of a larger jobsite evolution that’s changing the way work gets done. New and safer batteryoperated solutions redefine light equipment, including core drills. These solutions offer user-driven designs, including Engineering Controls that supply safety, productivity, and ease of use. Kevin Gee is the group product manager for Milwaukee Tool Corp.

The Traker from Aaron Hilbert LLC

The Traker is a manual tool for installing contraction joints in concrete slabs-on-ground. Compared to sawcuts, Trak Joints are four times faster, 75% less costly, and dust free. The joints are installed early—immediately before or after bull-floating, while the concrete is highly workable. The early entry joints cause cracks to appear typically the day after placement. The Traker uses a roll of plastic tape resting against an insertion disc. The insertion disc folds and embeds the tape into fresh concrete. The top edge of the tape is pushed slightly below the concrete surface. The tape remains in the slab to create a weakened plane.

Zinc vs. Bronze: Concrete Hand Tools


ronze tools are the trusted means of achieving radius edges and straight control joints in concrete. Their rugged construction has the optimal weight distribution to provide professional quality results. For that reason, bronze tools are often fundamental for many concrete finishers. Yet this preference comes at a price. The monetary and human cost of bronze production is taking its toll on the industry, but it doesn’t have to. There is an alternative material available—zinc. Although they differ in composition, bronze and zinc share similar properties. They rival each other in terms of hardness, durability, quality construction, and professional finish results. Zinc, however, has a few added perks. Zinc production offers relief to the pocketbooks of contractors and manufacturers. For every bronze tool produced, two zinc tools can take its place. This results in less money wasted on tools that provide identical results. Plus, it’s safer for manufacturers to produce. COMPOSITION & PROPERTIES Bronze is an alloy of copper that has been in use for over 5,000 years. It is typically a combination of copper and tin, aluminum, or nickel (among others). Most concrete tools are 88-90% copper and 10-12% tin. This composition is great for tools due to its strength, hardness, and very high ductility. These properties also provide a high loadcarrying capacity, good wear resistance, and offer high durability. Unfortunately, it is also prone to corrosion. With enough air exposure, a bronze tool can oxidize and turn green. This green layer, called patina, is often the first sign of wear. The patina can act as a protective barrier, but if chlorides are present (as from seawater, soil, or sweat), these tools can develop “bronze disease.”


CONC1021_64_HandToolsarticle.indd 64

This is the death of a cuprous (copperbased) tool. It is a contact-contagious condition that works through the metal and destroys it. Once this happens, there is little chance to stop it. Zinc’s non-cuprous properties allows it to avoid this disease with a hexagonal closepacked crystal structure. It also possesses moderate hardness and can be made ductile and easily worked at temperatures slightly above the ambient. Side by side, bronze and zinc both have a hardness that is ideal for tools (on the Mohs Scale of Hardness for Metals, zinc = 2.5; bronze = 3).

For concrete finishers, the difference between bronze and zinc is slim to none. Both provide concrete tools with a high load-carrying capacity, good wear resistance, and the ability to produce virtually identical finish results. Zinc just doesn’t carry all the same drawbacks—it’s lightweight, easy to use, resistant to bronze disease, and cost-effective.

THE COST OF PRODUCTION The monetary and human cost of production is where bronze and zinc significantly diverge. Bronze production relies on two methods of production (sandcasting and die-casting), but neither are cost-effective for manufacturers. The result is manufacturers potentially passing this financial hardship onto contractors. Regardless of casting method, both involve grinding and deburring. This gives bronze tools their smooth, shelfand job-ready finish creating dust that requires immediate filtration or ventilation. Without this, workers can develop a condition known as pneumoconiosis or “dusty lung,” a condition that causes scar tissue to build up in the lungs and can lead to chronic lung, liver, kidney, and even brain problems. Because of these hazardous conditions, some U.S.-based manufacturers are no longer willing to put their workers at risk and ousourcing the job. But even those outsourced manufacturers are calling for an end to bronze production and the grinding involved. With fewer manufacturers at home and abroad producing bronze, bronze tools will be harder to acquire, driving an increase to price.

Zinc production, on the other hand, doesn’t carry these same costs. This is due in part to the development of the rapid quenching zinc-lead blast furnace in the 1960s, which uses shock-cooling and vapor absorption to produce zinc. : • Low working temperatures lead to rapid cooling of the cast products and fast production for assembly. • More precise casting methods eliminate the need for grinding and deburring. It also helps to produce a better, smoother, and more crisp finish on the edges and control joints of concrete slabs. • Zinc suppliers are U.S.-based, lowering the cost of production and (subsequently) retail value. Bronze and zinc share a high loadcarrying capacity and good wear resistance, ideal for concrete work, while zinc takes it a step further with immunity to bronze disease and a lighter, easier-to-use profile that provides contractors with similar results.

Things to Consider Before Adding a New Service


f there was one common question I receive it's, "Brad, how do you know when to add another service?" This question, or some form of it, comes from young business owners desperate to find another income stream, and from seasoned owners realizing they need to expand their vocabulary and offerings. This topic seemed to be on the minds of many contractors, so let me share a few thoughts and observations that I've made over the past 20 years that might aid you in your own evaluation of growing your business.

WHEN NOT TO ADD SERVICES It might be helpful to address some poor times to add new services. • When your primary business is experiencing increased amounts of customer call-backs and rework. This strongly suggests that your focus on quality is in need of attention. Fix your quality problems first and you might not be tempted to expand. • When an employee says, "I've done that before." There is always an employee, usually a new hire, who can be quite convincing on what they’ve accomplished at previous companies. In most cases this type of worker may be a new hire for a reason. • When you notice increased competition. New competitors shouldn't send you looking for another service to provide. Competition, especially new competition, can be good for you. It often adds pressure to do things right the first time, can force better attention to details, and generated a more creative mind set for marketing and sales.


CONC1021_66-68_LastPlacement.indd 66

WHEN TO ADD NEW SERVICES Now, there are certainly more reasons why you might want to think twice before adding new services but let me provide you some proactive, positive reasons to add new services. • Will adding a new service compliment and further expand business opportunities with existing clients? This is the primary reason to add a new service. If your current and paying customers are asking you to take on additional services, this is a good sign that you and your crews are doing a good job on meeting customer needs and consistently providing quality. • When your profitability is running consistently higher over the past season or two. It's doubly difficult to acquire additional equipment, add another crew, and learn another service if you are not making much money. Profits are good; they should be used to reinvest into your company. Expanding into new services is made easier when you're profitable. • When a specialty contractor is technically proficient but has little to no business savvy. It is just amazing how many technical experts get into power washing, curb and gutter, infrared application, sealcoating etc. who can't run a business. Offering to buy one of these contractors out might be a "winwin" for both you and the businesschallenged owner. • When there is a new geographical opportunity available and it could be getting your foot in the door. Contractors have begun a new service


where they have little to no current business at and then use this new addition as a lead-in for their existing services. This is sort of coming through the back door, but it can be a strategy to add a new service that ironically opens the chance to do more business with current services. Certainly one or more of these four criteria should be in place before you expand. It is important to also note that if you are seriously looking at adding a new service, develop a business plan addressing such topics as: market needs, competitors, cost of needed equipment, suppliers and their locations, and type of customers, to name just a few areas. Adding a new service will require that you have the proper attitude and mindset—it will renew your commitment to be patient and consistent. Plus, prepare to have the capital needed to keep the new service moving ahead while you and your workers are learning the new business. Adding a new service should be a positive and profitable experience. If you've never added a new service you are in for a real challenge to your old policies and approaches. Be open to new lessons and best practices that you can learn and even pass on to your existing services. You might just end up adding a service that becomes the new profit leader for your company in the future.
