Thoroseal Waterproofing

Thoroseal Waterproofing Solutions for NYC Buildings

Thoroseal Waterproofing is one of the most effective solutions for protecting basements and foundations in New York City. With heavy rainfall, aging masonry walls, and constant moisture exposure, NYC properties need strong and reliable waterproof coatings. Thoroseal creates a durable waterproof barrier that protects concrete and masonry surfaces from water penetration.

Many NYC homes, brownstones, and commercial buildings have porous foundation walls. Over time, water seeps through these surfaces, causing dampness, mold growth, and structural damage. Thoroseal Waterproofing is specially designed to seal these surfaces and prevent moisture intrusion before it becomes a serious problem.

Our Thoroseal Waterproofing services in NYC are customized for local building structures, soil conditions, and weather patterns. We focus on long-term protection that keeps your basement and foundation dry year-round.

Signs You Need Thoroseal Waterproofing in NYC

Many property owners do not notice moisture problems until damage becomes visible. Early waterproofing can prevent expensive structural repairs.

You may need Thoroseal Waterproofing if you notice:

  • Damp or wet basement walls
  • White powder residue (efflorescence)
  • Peeling paint on masonry surfaces
  • Musty basement odors
  • Mold growth near foundation walls
  • Small water leaks after heavy rain

If you see any of these warning signs, a professional inspection can determine whether Thoroseal Waterproofing is the right solution for your building.

Our Thoroseal Waterproofing Process

Our process is designed to provide strong, long-term protection with minimal disruption. 

1. Detailed Inspection
We examine basement walls, foundations, and masonry surfaces to identify water entry points.
2. Surface Preparation
Proper preparation is critical. We clean the surface, remove loose material, and repair cracks to ensure maximum adhesion.
3. Crack & Joint Repair
All visible cracks and gaps are sealed before applying Thoroseal.
4. Thoroseal Application
We apply the Thoroseal coating evenly across the surface to create a waterproof barrier.
5. Final Inspection & Testing
After curing, we inspect the area to ensure complete coverage and effective moisture resistance.

This process ensures your Thoroseal Waterproofing system performs reliably during heavy rain, snowmelt, and seasonal groundwater pressure.
