HDPE geomembrane (also known as waterproofing membrane), thickness ranging from 0.2mm to 3.0mm, and over 0.8mm thickness is referred to as waterproofing board. It is a waterproof and barrier material made primarily from high-quality polyethylene prime resin. The main component is 97.5% high-density polyethylene, with approximately 2.5% of carbon black, anti-aging agents, antioxidants, UV absorbers, stabilizers, and other additives. It boasts strong waterproof and isolation properties.
