Foundation & Basement Waterproofing

What We Do

Water in a basement is almost never a basement problem — it is a drainage, grading, or foundation problem that shows up in the basement. We trace the actual entry path, then install the right system for it: interior perimeter drainage and a sump pit for hydrostatic seepage, exterior membrane and footing drains where excavation is viable, and injection repair for active cracks in poured concrete.

Bronx and Westchester housing stock is old enough that most below-grade walls were built with no membrane at all, or with a coal-tar coating that gave up decades ago. Add clay-heavy soil that holds water against the wall after every storm, and seepage becomes seasonal and predictable. Coating the inside of a wet wall does not fix that — it traps the water and pushes the problem sideways. We do a moisture-source assessment first, tell you plainly whether you need interior management or exterior exclusion, and price both so you can see the trade-off. All work is performed by our own crews, fully licensed and insured in New York State.

• Interior perimeter drainage, sump pits & battery-backup pumps
• Exterior excavation, membrane & footing drain installation
• Poured-concrete crack repair — polyurethane & epoxy injection
• Cove joint & floor-wall seepage sealing systems
• Vapor barriers, negative-side coatings & crystalline slurries
• Grading & downspout correction to move water off the foundation
