We waterproof new foundations during construction and repair water problems in existing basements, for both residential and commercial buildings. Free estimates: 646-552-0335.
What We Do
- Foundation membranes — sheet and fluid-applied membranes on new and existing foundation walls
- Damp-proofing & parge coats — protective coatings that seal below-grade concrete and masonry
- Footing drains & drainage — perforated drain pipe, gravel backfill, and drainage board that move water away from the foundation
- Basement waterproofing — stop active leaks and seepage in existing basements and cellars
- Waterproofing during construction — we waterproof foundations we pour, so the protection is built in from day one
Why It Matters In Nyc
New York's freeze-thaw cycles, clay soils, and tight lot lines push water straight at your foundation. Waterproofing done during construction costs a fraction of digging a finished foundation back up later. For commercial buildings, water intrusion also means mold liability and tenant complaints — problems that cost far more than the membrane that prevents them.
Process
- Inspection & estimate — we assess the foundation, grading, and water path; free estimate
- Excavation & prep — expose and clean the wall (for existing buildings)
- Membrane / coating installation — the right system for the wall and water conditions
- Drainage — footing drain, drainage board, and gravel backfill as needed
- Backfill & restore — grade away from the building and restore the surface

Frequently Asked Questions
Q: Do you waterproof existing basements or only new construction?
Both. We waterproof new foundations as we build them, and we excavate and waterproof existing foundation walls for homes and commercial buildings with active water problems.
Q: What's the difference between waterproofing and damp-proofing?
Damp-proofing is a coating that resists soil moisture; waterproofing is a membrane system that blocks liquid water under pressure. We'll recommend the right level of protection for your soil, water table, and building use.
Q: Do you handle the drainage too?
Yes — footing drains, drainage board, and gravel backfill are part of the same job. Waterproofing without drainage is only half the fix.
Q: Do you serve both homes and commercial buildings?
Yes. We waterproof everything from single-family basements to full commercial foundations across NYC's five boroughs and Nassau County.
