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.

  • Advantages
  • Performance

1.It has double functions of waterproof and plant root penetration resistance. It can be resistant to plant root and resistant to water permanently; It doesn’t affect plant growing while being resistant to plant root punctures;
2.It can form a high strength waterproof layer, strong resistance to water, resistance to puncture, breaking, tearing and fatigue;
3.High tensile strength, large thickness of modified bituminous coating, and it is very adaptive to the shrinkage, deformation and fracture of base.
4.Excellent low and high temperature resistance, it can be adaptive in both hot and cold regions.
5.Excellent performance of corrosion resistant, mould resistant and weather resistant; 6.It uses heat fusion method, which is convenient, reliable and durable.
