What geosynthetic products do you manufacture?

Our main product range includes HDPE, LDPE and LLDPE geomembranes, nonwoven  geotextiles, Geosynthetic Clay Liners (GCL), composite geomembranes, composite drainage network, geogrids and so on. Depending on the project, we can supply individual products or coordinate a complete geosynthetic lining system.

How do I choose the right geomembrane for my project?

The selection should be based on the project design, contained material, chemical exposure, substrate conditions, settlement, slope geometry, installation requirements and applicable standards. HDPE is widely used where high chemical resistance and dimensional stability are required, while LLDPE offers greater flexibility and elongation. If you are unsure, send us your drawings or project specification and our technical team can help evaluate the suitable material and thickness.

What is the difference between HDPE and LLDPE geomembranes?

HDPE geomembranes generally provide high chemical resistance, stiffness and dimensional stability. LLDPE geomembranes are more flexible and offer higher elongation, which can be advantageous where the subgrade may experience movement or differential settlement. The best choice depends on the project design and service conditions rather than on material type alone.

When should I use a smooth or textured geomembrane?

Smooth geomembranes are commonly used on relatively flat surfaces and where low interface friction is acceptable. Textured geomembranes provide higher interface friction and are often selected for slopes or other applications where interface stability is important. The appropriate surface type should be determined from the project slope, adjacent materials and interface shear requirements.

What is a GCL, and when is it used with a geomembrane?

A Geosynthetic Clay Liner (GCL) is a factory-manufactured composite containing sodium bentonite between geotextile layers. When properly hydrated and confined, the bentonite swells and forms a low-permeability barrier. GCLs are commonly used as part of composite lining systems, including landfill and containment applications, where an additional low-permeability layer is required.
