Root puncture waterproof membrane refers to a kind of waterproof material used in engineering waterproofing construction. Root-resistant puncture waterproof membrane is a kind of PVC double-sided composite root-resistant puncture waterproof membrane with a copper tire base as a root blocking waterproof layer. It has long-term root (or rhizome) puncture resistance, strong adhesion, good stability, good low temperature flexibility and heat resistance, strong chemical corrosion resistance and radiation resistance, and still shows good root-blocking waterproof performance for more than 20 years. Material features 1. It has the dual function of waterproof and blocking the penetration of plant roots, can withstand the puncture of the plant root whiskers, and maintain the waterproof function for a long time; 2. It can prevent root puncture, and does not affect the normal growth of plants; 3. Can form a high-strength waterproof layer, strong resistance to pressure water, and resistance to puncture, rupture, tear, fatigue; 4. High tensile strength, large thickness of asphalt coating layer, shrinkage to the base Strong adaptability to shape and crack 5. Excellent high and low temperature resistance, suitable for hot and cold areas; 6. Corrosion resistance, mold resistance and weather resistance; 7. Hot melt construction, convenient construction and reliable and durable hot joints. Construction Precautions 1. Construction should not be carried out on rainy, snowy days and windy days above grade 5; the temperature of the construction environment should not be lower than 0℃. 2. The nozzle of the flame heater should be at a moderate distance from the coil surface, and the heating should be uniform within the width, to the extent that the coil surface melts to bright black, and the coil must not be heated excessively. 3. The construction site has complete protective facilities, and firefighting equipment is placed according to regulations.
