Geomembrane Liners

Rowad is a specialist manufacturer in the production of HDPE (High-Density Polyethylene) and LLDPE (Linear Low-Density Polyethylene) geomembrane liners utilizing state-of-the-art blown film and flat die extrusion processes.

The use of polyethylene (PE) flexible geomembrane liners has now reached the point of almost universal application, where many projects specify geomembrane linings. Geomembrane linings are universally accepted design and construction elements as they:

• Provide technical and cost advantages over more traditional methods of construction, particularly in areas of active and dispersive soils and heaving clays

• Maintain flexibility and integrity when more rigid materials will crack

• Reduce layer thickness, increase available void space and reduce costs of construction

• Follow precise MQA (manufacturing quality control) and CQA (construction quality control) procedures applied for manufacture and in construction

• Are highly durable, resistant to weathering and climatic effects and offer resistance to a wide range of chemical solutions

• Are flexible both in nature and in use and can be used for lining around irregular geometrical profiles

• Are safe for long-term storage of potable water because they are non-toxic and chemically inert; Rowad linings are potable water approved by a number of key international institutions
