The Environment

Geosynthetics play an important role in environmental applications because of their versatility, cost-effectiveness, ease of installation, and good characterization of their mechanical and hydraulic properties. Geosynthetics also can offer a technical advantage in relation to traditional liner systems or other containment systems.

Geomembranes are impermeable membranes used widely as cut-offs and liners. Until recent years, geomembranes were used mostly as liners for canal and ponds; however, one of the largest current applications is the containment of hazardous or municipal waste and their leachates. In many of these applications geomembranes are employed with geotextile or mesh underliners which reinforce or protect the more flexible geomembrane whilst also acting as an escape route for gases and leachates generated in certain wastes.

Building

The structures with deep foundations should sometimes deal with high groundwater table problems. GCL as well as PVC geomembrane are the most common geosynthetic solution for waterproofing underground structures in the buildings. Having International standards, Simple installation and better performance make it a very favorable option for contractors and project owners to use such material. For water proofing of underground structures a special type of GCL and PVC geomembrane are used.

Using PVC and GCL for waterproofing foundation is a safe technology to protect the construction against destructive influences of the water.

The experience of the past has shown that PVC is the most adapted product for foundations, concerning mechanical characteristics (puncture resistance), handling, and durability. High puncture resistance is important seeing the procedure of backfill, and the high pressure due to the weight of building.

Irrigation and Canal Liner

There’s three ways to control seepage in irrigation applications: a clay system, a concrete system and a geomembrane liner. Clay systems only reduce the amount of seepage of irrigation water into the groundwater and concrete systems are usually very expensive to implement. More and more professionals opt for geomembranes such liners. It’s a flexible and reliable system, with options for short, mid- and long-term irrigation canal applications

Solutions for Aquaculture
Raising fish and other aquatic species in lined ponds is a growing use for geomembranes. The key to the success of these aquaculture applications is the selection of a suitable geomembrane that will not harm the fish. Different species of fish can be sensitive to different aspects of a geomembranes.
