Physical Properties of Geomembranes

Geomembranes have high tensile strength and puncture resistance making them ideal for applications requiring physical barriers. Their enhanced elasticity allows them to conform to irregular surfaces without tearing. Modern geomembranes also have excellent resistance to weathering, ultraviolet radiation, and chemical degradation which enables them to maintain integrity over long periods of time when exposed to outdoor environmental conditions.

Durability and Long Service Life

The tough and durable composition of geomembranes means they can withstand stresses from overlying materials, settlements, and extreme weather without damage. With proper installation and protection, modern polyethylene and polypropyrene Geomembrane can provide an effective barrier for tens to hundreds of years. This long service life makes them highly cost-effective compared to traditional earthen liners which may require replacement after several decades.

Applications in Water Management Projects

Geomembranes are extensively used in water containment and pollution control projects. Some common applications include -

- Reservoir and canal liner systems to prevent seepage losses and maintain water quality.

- Landfill liner systems beneath waste deposits to isolate leachate and prevent groundwater contamination.

- Debris basin and sediment pond liners for erosion and flood control.

- Canal siphon liners to enable water transfer through embankments.

- Containment at industrial and mining sites for liquids, sludge and residues.

- Below-ground vault seals and underground tank seals.

The continuous barrier provided by geomembranes is highly effective for managing water and preventing pollution ingress or egress from containment areas.
