GP-PAM EVA Polymer Self-adhesive Waterproof Membrane

EVA polymer self-adhesive waterproofing membrane is a self-adhesive waterproofing membrane with polymer sheet as surface (or base), butyl, styrene and other polymer modified asphalt as self-adhesive material, and is compounded by special process. It solves many difficulties in the construction of polymer waterproofing sheet, and at the same time combines some characteristics of polymer sheet and self-adhesive membrane, thus realizing superimposed waterproofing function.
