Waterproof boards are a type of impermeable material made from high polymer plastics, which can prevent both liquid leakage and gas volatilization. They are widely used in construction, transportation, subway, tunnel, and engineering projects.

Waterproofing sheet, also known as geotextile membrane, is commonly referred to as waterproofing sheet for materials thicker than or equal to 0.8mm, and geotextile membrane for those thinner than 0.8mm. It is a type of waterproofing material made from high polymer materials, and it is categorized into homogeneous waterproofing sheet and composite waterproofing sheet.

Waterproof sheets for underground anti-corrosion and leakage prevention projects, the new HDPE waterproof sheets, are formulated by recombination, using low-pressure high-density polyethylene material, and scientifically blending carbon black, anti-aging agents, antioxidants, UV absorbers, and stabilizers. They are produced using the latest fully automatic geosynthetic production equipment internationally, through triple co-extrusion technology. This production line is highly automated, with computerized full control from order input, formulation, raw material input, processing, to quality monitoring, strictly following scientific data. It can also use raw materials with excellent tensile strength, such as HDPE, EVA, LDPE, etc. All products are produced in accordance with the American ASTM D standard, meeting or exceeding national standards. Product specifications range from 0.2mm to 2.5mm in thickness and 1m to 8m in width, meeting the leakage and anti-corrosion requirements for projects like artificial lake leakage prevention, sewage pool leakage prevention, reservoir leakage prevention, environmental protection, and mining & chemical industries.
