GEOMEMBRANE WELDING

 

Geomembranes are impermeable geosynthetics, designed to deal with fluid migration control, such as pond liners and canals. It's application is wide, ranging from mining to water management, agriculture, construction, industrial and oil/gas sectors. The properties of geomembranes include great chemical, temperature, ultraviolet and puncture resistance.

​

E&E works with a wide range of geomembranes, the most common ones as it follows :

​

​

PVC LINERS

​

Poly Vinyl Chloride (PVC) is the most common lining material available. It is a non-reinforced, highly flexible and cost-effective waterproofing geomembrane. PVC has high puncture strength, good chemical resistance and abrasion resistance. Due to its high flexibility, this kind of liner conform to sub grade contours and offer excellent interface friction without being textured.

​

​

​

Polyethylene LLDPE LINERS (linear low-density)

​

LLDPE are geomembranes specially conceived for waste containment applications that require superior flexibility and elongation performance. LLDPE liners are also puncture, UV and chemically resistant, offering long performance and great durability.

​

​

​

Polyethylene HDPE LINERS (high-density)

​

HDPE is the most chemically resistant member of the polyethylene family. It is the most commonly used membrane for containment structures, such as solid waste landfills, power plants, aquaculture and concrete tank ponds. It offers great ultraviolet protection and ageing resistance from the intense stresses of weather. Although less flexible than its LLDPE counterpart, it still offers great elongation properties.

​

​

​

BGM (Bituminous Geomembrane)

​

The combination of different layers of materials creates a geomembrane with superior flexibility that enables it to adapt to any ground contour. This particular geomembrane has proven itself a practical and durable liner solution for tough and changing environments. It's application varies, being commonly seen at ponds, reservoirs, mining waste management, damns and settling bassins.

​

​

GCL (Geosynthetic Clay Liner)

 

A duo of geotextile and bentonite composites that offer a long last resistance to physical or chemical agents. Bentonite is a natural sealing component, that hydrates itself in contact with water, forming a low permeability clay liner with hydraulic conductivity. The hydraulic protection of GCL's is equivalent to one meter of compacted clay.
