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.

Simpson Strong-Tie Titen Turbo Concrete and Masonry Screws
The Titen Turbo line of concrete and masonry screw anchors features a patented thread design to deliver smooth driving with less torque and superior holding power. Titen Turbo screw anchors are ideal for attaching all types of fixtures to concrete and masonry and feature an innovative torque-reduction channel to trap drilling dust where it can’t obstruct thread action, significantly reducing binding, stripping and snapping without compromising strength. The reverse thread design also allows more space for dust to help prevent anchors from bottoming out in smaller-diameter screw holes.
Available with either a hex head or a 6-lobe countersunk head for a smoother installed profile, Titen Turbo screw anchors feature a serrated leading edge to cut into concrete or masonry, and a pointed tip for fast, easy installation in wood-to-concrete and wood-to-wood anchoring applications.

PERI QuickSolve by PERI Formwork Systems
PERI Formwork Systems Inc.'s PERI QuickSolve (enhanced edition) is a free web-based planning tool that empowers contractors and estimators to sketch out a project and identify the best wall formwork solutions based on the specific characteristics of that project.
With the enhanced edition of PERI QuickSolve, customers can import their PERI formwork inventory in an Excel file and obtain an automatic evaluation of formwork and accessories needed to complete a design. The update also makes it easier to draw walls at an angle to match the layout of a project more effectively. Beyond providing a parts list that includes product numbers, quantity, and weights, the new QuickSolve also delivers product images for easier visual interpretation. In total, the improvements to QuickSolve enhance job site communication, potentially eliminating errors during ordering and installation and minimizing on-site material needs.

Cortec's MCI-2020 Rebar Corrosion Protection
Corrosion of metal reinforcement is one of the most serious threats to the durability of concrete structures. 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.
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.

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, www.peri-usa.comSE., 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.
