Services
Thermal Grouting
Thermal grouting enhances underground electrical utility efficiency by dissipating heat from conduits, extending insulation lifespan and reducing long-term costs. Our team develops specialized mix designs and employs advanced techniques for projects ranging from short bores to record-breaking 11,000-foot installations. With expertise in HDD and cased bores, we ensure compliance with engineering standards and deliver precise thermal resistivity results.
Dam Seals
Dam seals address water infiltration in concrete structures by retrofitting failed waterstops or managing alkali-aggregate reaction expansion. We install in-situ seals for major clients like the U.S. Army Corps of Engineers, using specialized techniques for deep and large-diameter applications. Our solutions combine durability with precision, ensuring long-term structural integrity for critical infrastructure.
Anchors and Load Testing
We provide tieback installation, soil nailing, and load testing for support-of-excavation systems, including projects with depths exceeding 60 feet. Our services include on-site training, digital reporting within 24 hours, and testing capacities up to 930 kips. This ensures structural stability for complex urban developments and infrastructure upgrades.
Structural Repairs
Our structural repair expertise includes carbon fiber reinforcement, post-tension grouting, and balcony restoration for commercial and public facilities. We specialize in minimizing disruptions during repairs, using hydraulic jacking systems and helical pile foundations for precision leveling. Projects like the Wildwood Convention Center highlight our commitment to preventive maintenance and durable solutions.
Specialized Equipment Design
We design and implement custom equipment for construction challenges, such as segment-setting systems for elevated roadways and void-measuring technology for post-tensioned structures. Our solutions prioritize safety, efficiency, and reliability, as demonstrated in projects like the Lee Roy Selmon Crosstown Expressway, where we optimized automation and control systems for rapid deployment.
