Crawl Space Waterproofing
A complete, built-to-last approach for protecting crawl spaces in Connecticut and New YorkCrawl space water problems rarely come from a single source. Ground moisture, rising groundwater, and unsealed surfaces often work together below the home, quietly affecting air quality, comfort, and structural conditions above.
At American Dry Basement Systems, our crawl space waterproofing solutions are designed to control water at the source, seal exposed areas, and deliver reliable, long-term protection. This page outlines the crawl space services we offer and helps you understand which solution fits your home.

What is Crawl Space Waterproofing?
Every crawl space behaves differently. During your free inspection, we evaluate:
- Water entry points and groundwater behavior
- Crawl space height and access
- Existing liners, floors, or drainage
- Structural and mechanical constraints
Some homes need sealing only. Others require sealing combined with drainage or a sump pump system. Our recommendations are based on conditions—not sales pressure.
Our Crawl Space Waterproofing Services
Crawl Space Encapsulation
Before and after encapsulating a crawl space in Westport, CT
Best for crawl spaces with persistent moisture, damp soil, or exposed earth.
Our crawl space encapsulation system creates a clean, sealed environment by isolating the space from ground moisture and outside air. When needed, it can be combined with drainage or pump systems for added protection.
Encapsulation may include:
- Full ground liner coverage
- Wall sealing with SuperSlurry
- Integration with drainage or pump systems
Crawl Space Sealing
Before and after crawl space Supercrete sealing in Harrison, NY
Best for homeowners seeking durability, access, and long-term value.
Our crawl space sealing system replaces thin plastic liners with a poured SuperCrete concrete floor over a vapor barrier. The result is a solid, walkable, tear-resistant surface that cleanly separates your home from the earth below.
Crawl space sealing includes:
- Careful clean-out and preparation
- Vapor barrier installation
- SuperCrete concrete floor system
Crawl Space Sump Pump Systems
Primary sump pump & backup battery with wifi installation.
Best for crawl spaces affected by rising groundwater or flooding risk.
When water pressure builds below the crawl space, sealing alone isn’t enough. A properly designed sump pump system collects and removes groundwater before it becomes a problem.
Our crawl space pump systems may include:
- Subfloor drainage where required
- Primary pump with optional backup systems
- Proper discharge away from the foundation
