Enhanced Investigation and Support

Whether it’s part of a proactive program or in response to identified structural or deterioration issues, STRUCTURAL TECHNOLOGIES offers a range of specialized investigation services to assist engineers with the assessment of infrastructure. Our specialized services are designed to help identify the true root cause of deterioration as well as provide more comprehensive quantifiable information to aid in the solution-building process.

Working with engineers and our contracting licensees, STRUCTURAL TECHNOLOGIES supports the investigation process in many ways, including: • Specialty Corrosion Control Testing

Common Infrastructure Problems • Deteriorating concrete, delamination, spalling • Water leakage through cracks and joints • Corroding steel reinforcement and members • Worn and defective joints • Corroding PT tendons and anchorages • Freeze thaw damage • Stress corrosion • Defective workmanship • Design defects • Damage due to vibration and movement • Crumbling foundation due to pyrrhotite

contamination

• Drone and other digital capture and modelling capabilities • Advanced concrete testing and STADIUM® service life modelling • Water intrusion investigation support Typically brought in as a supplement, or as a subcontractor to engineers, our NACE certified corrosion experts provide specialty investigation and testing related to concrete and steel deterioration. Evaluations involve a variety of nondestructive and exploratory testing methods to determine the state of components and the surrounding concrete.

Additionally, our SMEs can also help evaluate structural integrity as part of our design-assist approach to the use of our innovative strengthening products.

Through STRUCTURAL TECHNOLOGIES' partnership with SIMCO Technologies, SIMCO's STADIUM® service life modelling can provide estimated remaining service life based on deterioration levels and exposure conditions.

A challenge faced by owners, engineers and contractors of commercial and public infrastructure is combating concrete deterioration.

Through STRUCTURAL TECHNOLOGIES' investment and partnership with SIMCO, our team offers industryleading service life prediction services to engineers and their clients.

Service Life Modelling / Design for Existing Structures By incorporating SIMCO’s durability modeling into the investigation phase of a project, engineers can better understand the remaining service life of the structure without interventions and optimize repair solutions. With the STADIUM® modeling software, we can predict: residual service life or time to failure without corrective measures and predictive service life extension for repair strategies.

SIMCO's STADIUM® Prediction Tool The U.S. Department of Defense recognizes STADIUM® as an accurate solution for the prediction of long-term behavior of reinforced concrete structures exposed to a wide range of aggressive environments. Unlike other models, STADIUM® considers a wide range of physical and chemical factors that influence long-term performance and overall service-life.

Moisture Control Design Support

MOISTURE INTRUSION SOLUTIONS Moisture problems are often critical issues that must be addressed quickly in order to maintain functionality, create longterm durability, and avoid other related deterioration that could dramatically increase the cost of repair in the future.

The presence of water, cracking, peeling coatings, rust stains and spalling concrete are visible signs of moisture problems – but these symptoms must be analyzed to identify the root cause of the issue before developing the best repair solution.

Our Solution Builders have extensive experience identifying sources of water intrusion and developing a range of alternative solutions that fit budget and service-life requirements. Our expertise includes assisting in identifying the root cause and source of water problems, helping to select or providing the right materials, and aiding in the development of a constructible design solution that can be implemented properly in the field.

ENGINEERED MOISTURE CONTROL & WATERPROOFING SYSTEMS Our design team and subject matter experts choose from a variety of materials, methods and technologies to develop customized moisture control solutions: COATINGS • Rigid • Elastomeric MEMBRANES • Thermosetting polymer sheets • Vulcanized rubber sheets • Composite systems JOINT SEALS • Pressure-rated water stops • Water control sealants • Load supporting glands • Expansion joints

INJECTION GROUTING • Epoxy • Structural urethane(s) • Hydrophobic urethanes • Hydrophilic urethanes • Polyacrylate • Bentonite • Polymeric gel • Acrylamides • Sodium silicates • Micro-fine cements WATER MANAGEMENT We design customized water management and drainage systems to collect and direct moisture away from the structure.

ELECTRO OSMOTIC PULSE Electro Tech CP EOP™ provides the ability to mitigate moisture problems in concrete by lowering moisture transmission and content through concrete’s pore and capillary structure. Utilizing advanced controllers and components, our EOP system also provides the ability to eliminate, or significantly reduce, corrosion of reinforcing steel in concrete.

Concrete Repair Design Support

CONCRETE REPAIR SOLUTIONS Concrete cracking can be a minor issue or an indication of a waterproofing issue or a serious structural problem. It is important that proper techniques are used to analyze the existing concrete to determine the extent of the problem and to select the proper repair material and protection strategy.

STRUCTURAL TECHNOLOGIES has a unique approach to effectively evaluate deterioration mechanisms affecting reinforced concrete structures. We provide assessment services that help locate, quantify, and understand the root cause of deterioration in structures to determine the current condition of the structure beyond what is visible.

Our concrete repair solutions address defective, damaged, or deteriorated concrete; restore function; protect the underlying concrete from aggressive environments; and restore structural capacity.

Corrosion Protection Solutions

STRUCTURAL TECHNOLOGIES offers a full line of cathodic protection systems and has a staff of qualified professionals to help you design and customize your system and oversee installation by our licensed contracting companies.

ElectroTechCP™ EZ-Anode Systems

ElectroTechCP™ MCP Systems

ElectroTechCP™ ICCP Systems

ElectroTechCP™ EZ-Anode Systems are customizable galvanic cathodic protection solutions consisting of zinc mesh and a patented conductive mortar. The system is highly flexible as it is custom built and installed in the field for the long-term protection of reinforced concrete. Along with the base system, versions for different applications include: ElectroTechCP™ EZColumn System for concrete columns suffering from corrosioninduced damage and ElectroTechCP™ EZ-Balcony System for balconies suffering from corrosion-induced damage.

ElectroTechCP™ Metalized Cathodic Protection (MCP) systems deliver uniform corrosion protection to embedded reinforcing steel in concrete. Like other galvanic systems, the MCP system does not require external power. This spray-applied anode (often referred to as metallizing) can be coated for aesthetic purposes or can be reapplied for extended service life. The MCP System protects embedded steel in concrete members as well as exposed steel members of structural steel.

ElectroTechCP™ Impressed Current Cathodic Protection (ICCP) systems involve installing anodes and ribbons throughout a structure and passing a Direct Current (DC) through them to prevent corrosion. The system is driven and controlled by proprietary power and monitoring devices that deliver and monitor precise levels of protective current to embedded steel within concrete structures. Variable power supplies and sophisticated controllers allow for different levels of protection that can be continually adjusted within the structure. The controllers allow for remote monitoring and will alert operators of changing conditions.
