Crawl Space Waterproofing

Keeping your crawl space dry and free from mold

A crawlspace is susceptible to moisture and deterioration problems because of contact with the earth. New England Dry Basements can help prevent these problems in a number of ways.

You may find that your crawl space is consistently damp and musty.  This can be controlled by properly encapsulating the area with a vapor barrier.  A dehumidifier specially designed for crawl spaces may also be needed.

Additionally, If you have standing water in your crawl space we can provide a drainage system and sump pump, just like in a full basement.

Remember 50% of the air in your home comes from the basement or crawlspace!

Once the crawl space is dry, it can be properly insulated for better energy efficiency.

New England Dry Basements can help with all of this.

Here are a few crawlspace guidelines:

Keep all untreated wood materials away from the earth.

Provide a foundation drainage system at the footing when the foundation floor (interior grade) is below the exterior grade. Surround the crawlspace with a perforated Flat Track drain channel and gravel, and pitch to a sealed sump pump system.

Install 20-mil commercial grade reinforced vapor barrier across the crawl space floor to prevent soil moisture from migrating into the crawl space. Overlap and tape all seams by several inches. Seal completely up the crawl space walls and as an option, install a floor drainage system leading to a sump pump.

Install drainage plane material or gravel against the foundation wall to relieve hydrostatic pressure and channel water to the foundation drain.

Damp proof the below-grade portion of the foundation wall to prevent the wall from absorbing ground moisture by capillary action.

If your Massachusetts basement is wet or damp or moldy or it leaks, we can fix it.
