Block Wall Treatment

[Back to Crawl Space Products]

Installing a vapor barrier in a crawl space comes with one important challenge: covering the entire wall to protect moisture from passing through. If we coat all the walls and floor with an opaque covering, how will termite and pest inspectors be able to check for infestations?

Image on the right shows WallCap being installed in a crawl space with block wall.

A proper crawl space vapor barrier in Bellingham, Washington should be installed with a space left at the top around the entire edge to accommodate for this. This way, the common signs of an infestation- such as mud tubes from termite paths, can be easily sighted without needing to remove the layer.

Covering the tops of block walls will also protect your home from the enormous amount of exposure that the block openings adds to the home, helping to prevent moisture from passing upwards behind the CleanSpace and into the crawl space air.

This product is called WallCap and is available only through Basement Systems dealer network in Washington. Image on the left shows how our CleanSpace vapor barrier blends in with WallCap.
