Fixing a wet crawl space begins with high-performance products & technicians trained to install them


Our crawlspace waterproofing system includes a sump pump with battery backup (for protection during power outages) and a heavy-duty vapor barrier and a ventilation system.

Building scientists and other building experts recommend that crawl spaces be sealed or encapsulated. This upgrade makes buildings more energy efficient and eliminates problems with moisture, mold and pests in the crawl space. Some crawl spaces also need to be waterproofed.

How do I know if my crawl space needs waterproofing?

There are several signs that indicate a waterproofing system may be necessary in a crawl space. One obvious sign is standing water on the crawl space floor. If the crawl space has a dirt floor, wet soil can also indicate that a waterproofing system should be installed.

Products that promote good drainage. Installed beneath the vapor barrier, dimpled plastic drainage matting promotes good drainage along the crawl space floor. Drain pipe collects water from floor and wall leakage, transporting it to a crawl space sump pump.

What features are included in a crawl space waterproofing system?

If your crawl space needs waterproofing, the complete system is likely to include some or all of the crawl space repair solutions described below:

  • Perimeter drains. Patented perimeter drain pipe is designed to capture crawl space wall and floor seepage.
  • Drainage matting. This dimpled plastic sheet material promotes good drainage over the entire crawl space floor.
  • Sump pump. The best-performing sump pump systems available, including battery backup models that keep working even when the power goes out.
  • Dehumidifier. A dehumidifier from us will dry out a damp crawl space and automatically maintain a pre-set humidity level. By controlling crawl space humidity, you create conditions that are hostile to mold and mildew.
