Geomembrane Sheeting

Geomembrane Sheeting – refers to large, continuous sheets of synthetic membrane material used to create impermeable barriers for containment applications in civil engineering, environmental protection, and construction. These sheets are made from various types of polymers and are designed to prevent the passage of liquids, gases, or other substances.

1) Material Composition:

• Polymers like HDPE, LDPE, LLDPE, PVC, eEPDM, or PP are commonly used to make geomembrane sheets. Every material has unique properties that make it suitable for a variety of uses.

2) Thickness and Roll Sizes:

• Geomembrane sheets are manufactured in various thicknesses, usually ranging from 0.5 mm to 3 mm or more, depending on the application. They are supplied in large rolls, allowing for the coverage of large areas with minimal seams.

3) Impermeability:

• The primary function of geomembrane sheeting is to act as a barrier to prevent the movement of liquids or gases. This impermeability makes it ideal for lining landfills, ponds, and other containment systems.

4) Chemical Resistance:
Depending on the polymer used, geomembrane sheets can be highly resistant to a wide range of chemicals, making them suitable for hazardous waste containment and industrial applications.

5) Flexibility:
Geomembrane sheets can vary in flexibility depending on the material. More flexible sheets, such as those made from PVC or LLDPE, can conform to irregular surfaces more easily, while stiffer materials like HDPE offer higher tensile strength.

6) Weldability:
Geomembrane sheets are designed to be welded together using methods such as hot wedge welding or extrusion welding. This ensures that seams between sheets are watertight, creating a continuous barrier.
