HDPE Geomembrane
HDPE Geomembrane, also known as HDPE Anti-seepage Membrane, is a waterproof and isolating sheet produced through the process of film spraying, rolling, or co-extrusion by using HDPE virgin resin combined with 3%-5% high-quality dual-resistant masterbatch.
HDPE geomembrane acts as a robust barrier, effectively inhibiting the passage of liquids and gases. Its anti-leakage function makes it an ideal choice for various applications, including environmental protection projects, landfill lining, and containment systems. The use of HDPE Geomembrane with anti-leakage function ensures enhanced durability and reliability, providing an essential solution for maintaining the integrity of structures and safeguarding the surrounding environment from potential contaminants.
Types of HDPE Geomembrane
Smooth hdpe geomembrane
A smooth HDPE (High-Density Polyethylene) geomembrane is a type of geomembrane with a smooth surface texture.
Smooth HDPE geomembranes are characterized by their flat and smooth surface, which contributes to their impermeability and enhances their performance in preventing the passage of liquids.
Single-textured hdpe geomembrane
A single-rough surface geomembrane has one side with a relatively rough texture, distinguishing it from traditional smooth geomembranes. This rough surface may enhance adhesion with other materials and provide additional friction.
One of the primary functions of a single-rough surface geomembrane is to offer an anti-slip surface, improving stability when walking or placing other materials on it. This is crucial for projects that require enhanced stability. By increasing surface roughness, the geomembrane helps prevent soil erosion, protecting the surface cover from weathering and erosion effects.
Double-textured hdpe geomembrane
Double-textured HDPE geomembrane is high-density polyethylene (HDPE) geomembrane with rough textures on both sides, providing improved adhesion and slip resistance.
The double-textured design aims to increase the adhesion between the geomembrane and other materials, thereby enhancing stability in engineering projects. It is often used in projects with slopes, which can increased stability, adhesion, and slip resistance of the project, while mitigating soil erosion issues and enhancing overall engineering durability.
Advantages of HDPE Geomembrane
The first and most important funtion is its impermeability, providing an impermeable effect that ordinary impermeable materials cannot match.
The second is its high tensile strength and elongation at break, with a tensile strength of up to 27 megapascals and an elongation at break of ≥700%.
The third is its high chemical stability and aging resistance. It can withstand corrosion from strong acids and alkalis, and it is resistant to aging, UV radiation, decomposition, and freezing, making it suitable for outdoor use.
The fourth is its low cost and fast construction speed. The standard size of an HDPE geomembrane is 6 meters wide and 50 meters long, with a single roll covering an area of 300 square meters. A skilled welder can weld 3000 square meters in a day, a capability unmatched by traditional cement impermeability and other waterproof membranes.
