Delta-MS Clear is a translucent dimpled sheet for use with insulating concrete forms that protects foundations from water and moisture. It's clear, so web markings or attachment strips on ICF blocks remain visible. The waterproofing system includes an air-gap membrane that is vacuum-formed from high-density polyethylene and stabilized against oxidation. The result is a product that water, water vapor, soil acids, and other agents cannot penetrate. Cosella-Dörken Products, 888-433-5824,
