Foundation Waterproofing Services in New York City

B&P Consulting Corp provides professional foundation waterproofing services throughout New York City. Our experienced team specializes in both interior and exterior foundation waterproofing solutions that protect your building from water infiltration, structural damage, and mold growth. We serve residential and commercial properties across Brooklyn, Manhattan, Queens, and the Bronx.

Our Foundation Waterproofing Process (Step by Step)

Foundation Inspection — We thoroughly inspect your foundation walls, floor, and drainage systems to identify all sources of water infiltration and structural concerns.

Moisture Testing — Using professional moisture meters and thermal imaging, we map the extent of water penetration and identify hidden problem areas.

Surface Preparation — Foundation walls are cleaned, repaired, and prepared for waterproofing membrane application. All cracks and joints are sealed.

Waterproofing Application — We apply a multi-layer waterproofing system using premium SOPREMA products, including liquid-applied membranes and sheet membranes as appropriate.

Drainage Installation — Proper drainage systems are installed to direct water away from the foundation, including French drains, sump pumps, and exterior drainage boards.

Protection & Backfill — Protection boards are installed over the waterproofing membrane, and the excavation is carefully backfilled with proper drainage material.

Final Inspection — We conduct a thorough quality inspection and provide documentation of all work performed.

Materials & Brands We Use

SOPREMA COLPHENE — Self-adhesive waterproofing membrane for below-grade foundation applications.

SOPREMA ALSAN RS — Liquid-applied waterproofing for complex foundation geometries and penetrations.

SOPREMA SOPRADRAIN — Drainage composite boards that protect the waterproofing membrane and facilitate water drainage.

Hydraulic cement — For sealing active water leaks and structural cracks before membrane application.

Crystalline waterproofing — Penetrating waterproofing treatment that becomes part of the concrete structure.

NYC Building Code Compliance

All our foundation waterproofing projects comply with New York City building codes, including the NYC Construction Codes and DOB requirements. We handle all necessary permits and inspections, ensuring your project meets all regulatory standards for below-grade waterproofing.

Pricing Factors for Foundation Waterproofing

Foundation size and depth — Larger and deeper foundations require more material and labor.

Interior vs. exterior approach — Exterior waterproofing requires excavation, which adds to the cost but provides superior protection.

Severity of water infiltration — Active leaks and significant water damage require more extensive repairs.

Access conditions — Limited access in dense NYC neighborhoods can affect project logistics.

Drainage system requirements — French drains, sump pumps, and other drainage components add to the project cost.

Typical foundation waterproofing costs in NYC range from $15 to $35 per linear foot for interior solutions and $30 to $60 per linear foot for exterior waterproofing with excavation.

Frequently Asked Questions — Foundation Waterproofing

What are the signs that my foundation needs waterproofing?

Common signs include: water stains on basement walls or floors, musty odors, visible mold or mildew, efflorescence (white mineral deposits) on concrete, peeling paint, and standing water after rain. If you notice any of these signs, contact us for a free inspection.

Is interior or exterior waterproofing better?

Exterior waterproofing is generally more effective because it stops water before it reaches the foundation wall. However, interior waterproofing is often more practical in NYC where excavation access is limited. We’ll recommend the best approach for your specific situation.

How long does foundation waterproofing last?

Professional foundation waterproofing with premium materials typically lasts 15-25 years or more. The longevity depends on the materials used, soil conditions, and water table levels. We use SOPREMA products that are specifically designed for long-term below-grade performance.
