Services
Foundation Raising
Our foundation raising service addresses severely settled foundations using patented steel piering systems. Certified technicians install deep steel piers reaching stable bedrock to permanently lift and stabilize structures. This solution prevents further damage from soil movement while restoring structural integrity with minimal property disruption.
Concrete Leveling
Concrete leveling addresses uneven surfaces using PolyLEVEL injections. This high-density polyurethane foam fills voids beneath slabs, raising settled concrete and preventing future movement. The minimally invasive process works for driveways, sidewalks, and interior floors while maintaining existing surfaces.
Radon Mitigation
Our certified radon mitigation systems address dangerous radon gas infiltration. Using sub-slab depressurization technology, we install PVC piping networks and specialized vents to safely redirect radon gas away from buildings. The solution meets HUD guidelines for multifamily properties and includes ongoing maintenance options.
Crawl Space Repair
Crawl space repair services address moisture issues and structural instability. We install support jacks and moisture barriers to prevent floor sagging while improving home energy efficiency. The solution integrates with Basement Systems products for comprehensive waterproofing and long-term structural protection.
Crack Stitching
Crack stitching permanently stops concrete crack expansion using carbon fiber laminates. This method bonds high-strength materials across cracks to resist shear forces. The process involves precision cutting, laminate installation, and polyuria adhesive application to create durable, seamless repairs for interior and exterior concrete surfaces.
