1.It has the dual function of preventing the penetration of plant roots. It can withstand the puncture of plant roots and keep the waterproof function for a long time.
2.High tensile strength, high elongation, strong adaptability to shrinkage deformation and cracking of the substrate.
3.Good resistance to puncture, tearing, fatigue, corrosion, mold, weather.
4.Excellent resistance to high and low temperature, suitable for both hot and cold areas.
