Waterproof boards are a type of anti-seepage material made from high-molecular polymers as the basic raw material. They can not only prevent liquid leakage but also prevent gas volatilization. They are widely used in construction, transportation, subways, tunnels, and engineering projects.
Characteristics:
Strength - Under the same weight per unit area, the tensile strength in all directions is higher than that of other needle-punched non-woven fabrics.
UV resistance - It has a high resistance to ultraviolet light.
High-temperature resistance - It can withstand temperatures up to 230°C and maintain its structural integrity and original physical properties at high temperatures.
Permeability and planar drainage - The waterproof board is thick and needle-punched, providing excellent planar drainage and vertical water permeability, which can be maintained for many years.
Creep resistance - The creep resistance of the waterproof board is better than that of other geotextiles, thus ensuring long-term performance. It can resist erosion from common chemicals in soil and corrosion from gasoline, diesel, etc.
Elasticity - The waterproof board has a good elongation rate under stress, allowing it to adapt to uneven and irregular base surfaces.
Features:
1. Excellent flexibility, impermeability, elongation, and wear resistance;
2. Good isolation and puncture resistance;
3. No chemical pollution;
4. Resistant to acids, alkalis, and various chemicals, with good dimensional stability and adhesion, making it easy to install.
