TAMKO TWH-1 is a premium-quality protection course in an easily installed roll. The product is constructed with a heavyweight TAMKO organic mat, impregnated with hot asphaltic saturant then coated on both sides with weathering-grade asphalt and surfaced with mineral granules for superior scuff and abrasion resistance. TWH-1 is 1/8" thick, 36" wide and 33.3' long (100 square feet).

TWH-1 is used during the construction of plaza decks, roof terrace decks, parking decks or any other horizontal surface as a protective cover to provide protection to the waterproofing membrane during the installation of other work, and during the installation of a concrete wearing course, or any other succeeding course.

TWH-1 is specifically designed to protect the waterproofing membrane where moderate abuse is anticipated.
