Foam Board Insulation in a Yorktown, VA Crawl Space

Efflorescence on the walls and moisture stains on the block indicates that moisture has been working its way into this crawl space through the cinderblock foundation. 

As part of the encapsulation, Foamax foam board insulation has been installed on the walls of this crawl space creating a continuous R-10 of insulation on the foundation walls. A 2-inch viewing strip has been left at the top of the foundation wall per VA building code for termite inspections. The foam board is mechanically fastened to the wall and sealed at seams with foam.
