The System III moisture barrier application consists of three components: Ecoshield-P is a tough, nondegrading, laminated sheet that provides a substrate for the liquid membrane. Ecoline-S is a spray-applied, high-build, flexible, monolithic membrane used as a bonding gasket. The third component, Ecoshield-PP is a puncture-and abrasion-resistant fabric and film laminate that protects the other components from other construction damage and bonds to the concrete slab.
