In conjunction with the concrete foundation, most sites require a waterproofing membrane and drainage composite to be installed on the outer walls of the foundation to keep the buried portions of the foundation dry in service. Sometimes, crews apply the waterproofing membrane directly on the outside of the foundation walls after they strip the forms.

This latter method - applying the waterproofing before casting the walls- is called blind-side waterproofing, and it is the subject on which we'll focus here.
