Basement exterior insulation over waterproofing
Our basement exterior wall was waterproofed below grade today. The installation and warranty required the placement of material about 1/2” thick over the waterproofing. This material appears to be very permeable.
We are planning to insulate the basement from the exterior. Will this “unplanned” additional layer of permeable material cause any problems with our basement insulation? I was thinking that it might hold water if covered by rigid foam.
Any advice would be appreciated.
