Root penetration resistance of waterproof sheets for green roof system

Product introduction:

SBS/APP modified bituminous root penetration resistance waterproof sheet material is the material with Ligament polyester filler as the base, with SBS/APP modified asphalt adding chemical root resistance agent as cover materials, which has prevented the plant root penetration and waterproof functions of isolation material.
