      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.
