PRODUCT DETAILS

Product Introduction

High-density polyethylene (HDPE) geomembrane lining is a waterproof barrier material made from high-density polyethylene resin. It is an essential product for lining projects.

Performance characteristics

1. No heat treatment required; a new type of building material.

2. Excellent mechanical properties, good permeability, and resistance to corrosion and aging.

3. Strong resistance to burial and corrosion; loose structure with excellent drainage performance.

4. High coefficient of friction and tensile strength, providing geosynthetic reinforcement.

5. Functions including isolation, filtration, drainage, protection, stabilization, and reinforcement.

6. Adaptable to uneven base layers, resistant to construction damage, and exhibits low creep.

7. Good overall continuity, lightweight, and easy to install.

8. As a permeable material, it possesses excellent filtration and isolation functions; strong puncture resistance provides excellent protection.
