Name: High-Density HDPE Smooth Geomembrane Liner
Availability: InStock

High-Density Polyethylene Waterproofing Sheet Supplier

Primarily made from high-density polyethylene (HDPE), this impermeable lining serves as the foundation of HDPE geomembranes. Produced through calendering or blow molding, it forms a homogeneous, continuous, and impermeable barrier. Its primary ingredients are HDPE polymer resin, carbon black, antioxidants, and anti-aging agents.

NK's products are made from the highest quality raw materials and utilize advanced production technology to ensure that each product meets international standards. NK's geomembranes are exported to over 30 countries, including Indonesia, the United Arab Emirates, Australia, the Philippines, Malaysia, Mexico, and Myanmar, receiving unanimous praise.

Advantages & Strengths

Superior Impermeability:

Provides the lowest water vapor permeability, forming the most effective fluid (liquid and gas) barrier.

High Mechanical Strength:

Good tensile strength, elongation at break, puncture resistance and tear resistance.

Excellent Chemical Inertness:

Resistant to extreme pH values, a wide range of chemicals, solvents and hydrocarbons.

Excellent Weldability:

The flat surface ensures that hot wedge welding and extrusion welding can form continuous, high-strength, high-integrity welds, and weld detection (gas pressure/vacuum/electric spark) is highly reliable.

Long Service Life：

Adding anti-aging agents such as carbon black provides excellent UV and weather resistance, with a design life of over 50 years.

Popular Applications

Base Liner (60 mil HDPE Liner or 80 mil HDPE Liner):

Primary impermeable layer in horizontal or gently sloping areas such as landfills, tailings ponds, wastewater treatment ponds, and liquid storage tanks.

Capping System Barrier (2 mm HDPE Geomembrane or 1.5 mm HDPE Geomembrane):

Primary impermeable layer in a capping system (typically overlying a gas collection layer).

Secondary Containment (1.5 mm HDPE Liner or 80 mil HDPE Liner):

Impermeable lining for tank farms and process areas.

Horizontal Waterproofing (60 mil HDPE Liner or 40 mil HDPE Geomembrane):

Horizontal bottom surface impermeable layer for artificial lakes, reservoirs, landscape ponds, and aquaculture ponds.

Tunnel/Underground Waterproofing: Using 500 micron geomembranes:

Serves as a continuous lining waterproofing layer (requires an appropriate fixing system).
