Services
Interior Waterproofing
We install interior drainage systems and seal basement walls to prevent water intrusion. Our solutions address dampness, flooding, and moisture damage in residential and commercial properties. By using durable materials and advanced techniques, we ensure long-term protection against water-related foundation issues.
Exterior Waterproofing
Our exterior waterproofing services include applying protective membranes and coatings to foundation walls. This prevents groundwater from seeping into structures, safeguarding against cracks and erosion. We focus on proper grading and drainage to enhance system effectiveness and longevity.
Piering
We stabilize sinking foundations using steel piers driven to load-bearing soil or bedrock. This method lifts and supports structures affected by soil movement or poor compaction. Our piering solutions restore structural integrity for homes and commercial buildings with uneven floors or wall cracks.
Concrete Flat Work
We repair and level sunken concrete slabs using mudjacking or polyurethane injection. This cost-effective solution addresses trip hazards and drainage issues on patios, driveways, and sidewalks. Our techniques restore surfaces to their original condition with minimal disruption.
Crack Repair
We repair foundation cracks using epoxy or polyurethane injections to prevent water leaks and structural damage. This method restores wall strength and stops further deterioration. Our team assesses crack severity to determine the most effective repair strategy for long-term stability.
