The HDPE membrane, also known as a HDPE geomembrane, is a synthetic waterproof material widely used for containment and waterproofing applications in the environmental, civil, and industrial sectors.
There are HDPE geomembranes available on the market in different thicknesses. The solution we supply is the 2 mm thick HDPE membrane, recommended for applications requiring greater strength and long-term reliability.
What Is an HDPE Geomembrane
The HDPE geomembrane (high-density polyethylene) is a waterproof barrier designed to prevent the migration of liquids and gases into the ground. Thanks to its compact structure, HDPE ensures high chemical and mechanical stability even under critical environmental conditions.
ANELTEC HDPE membranes are available in a thickness of 2 mm.
Technical Characteristics of the HDPE Geomembrane
Mechanical strength
The 2 mm thickness allows the HDPE membrane to provide:
-
excellent resistance to tensile stress and puncturing
-
ability to adapt to movements of the substrate
-
long-term dimensional stability
Chemical resistance and durability
The HDPE geomembrane, due to the nature of the material and the 2 mm thickness, exhibits behavior suitable for use in environments where chemical agents commonly encountered in environmental and civil applications are present.
High-density polyethylene is characterized by:
-
low permeability and good stability against numerous compounds
-
limited sensitivity to agents present in soil and contact fluids, depending on operating conditions
-
adequate long-term durability, when properly installed and used in accordance with design specifications
The material’s response to external agents, environmental exposure, and aging is closely related to installation methods, operating conditions, and the application context.
Main applications of the 2 mm HDPE membrane
The HDPE geomembrane is commonly used in:
-
containment basins and tanks
-
controlled landfills
-
artificial lakes and reservoirs
-
hydraulic works and underground structures
Installation and welding of the HDPE geomembrane
Installation of the HDPE membrane is carried out by means of:
-
hot welding of the joints
-
leak-tightness testing of the welds
-
optional protection with geotextiles, including our Bentonite Geocomposite
Proper installation is essential to ensure the continuity and effectiveness of the waterproofing system.
Were you looking for our bentonite mat?
In many waterproofing applications, the HDPE geomembrane is used in combination with the bentonite mat to create a multilayer system. The combination of the two materials allows the continuous waterproofing performance of the HDPE membrane to be combined with the ability of the bentonite mat to adapt to the substrate, improving the management of irregularities in the installation surface.
