The waterproof membrane is suitable for various planting roof waterproofing projects, as well as various anti-puncture municipal, railway, water conservancy and other projects. OTAi root puncture resistant waterproof membrane has the following characteristics: 1. It has the dual functions of waterproofing and preventing plant roots from penetrating, which can withstand the puncture of plant roots and maintain the waterproof function for a long time; 2. It not only prevents root puncture, but also does not affect the normal growth of plants. 3. It can form a high-strength waterproof layer, has strong resistance to pressure water, and is resistant to puncture, cracking, tearing, and fatigue; 4. High tensile strength, large coating thickness, and strong adaptability to shrinkage deformation and cracking of the base layer; 5. Excellent high and low temperature resistance, suitable for hot and cold areas; 6. Good corrosion resistance, mildew resistance and weather resistance; 7. Hot-melt construction, convenient construction and reliable and durable hot joints.
