Services
Concrete Repair
Our concrete repair service utilizes mudjacking techniques to raise settled slabs back to original grade. By drilling small holes and injecting slurry, we restore sidewalks, driveways, and patios at half the cost of replacement. This minimally invasive method requires only 1-2 hours of downtime while eliminating trip hazards and preventing legal liability.
Foundation Stabilization
We stabilize settling foundations using compaction and helical pier systems. These steel piers are driven beneath footings to lift structures back to level positions. As an authorized PierTech dealer, we guarantee durable solutions for cracked walls and misaligned doors that restore structural integrity without major excavation.
Basement Excavation
Our basement excavation service creates additional living space by digging out existing crawl spaces. We support structures with temporary posts while excavating up to 8 feet deep, then install new foundation walls and egress windows. This adds square footage without altering the home's visible footprint.
Wall Straightening
We correct bowed foundation walls using wall pull systems that straighten structures and seal resulting cracks. This process involves installing steel supports on both sides of the wall to prevent future movement while restoring structural stability and safety.
Pressure Grouting
Pressure grouting fills voids beneath concrete slabs to lift and stabilize surfaces. This technique effectively raises settled floors, porches, and foundations by injecting slurry through drilled holes. The process restores level surfaces while preserving existing concrete integrity.
