Geomembranes

High-Performance Polymer Barriers for Environmental Containment & Water Infrastructure

Geomembranes supplied by Ten Geosystems are premium polymeric barrier liners engineered for long-term containment in waste management, water retention and environmental protection systems. Manufactured using high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) resins, Tengeo geomembranes provide reliable resistance to chemical attack, stress cracking, puncture and UV degradation. They conform to international guidelines including IGS, GRI-GM13/GM17, and relevant ASTM standards.

Manufacturing Processes

Geomembranes are produced through advanced blown-film or flat-die extrusion processes

Extrusion of HDPE/LLDPE resin compounded with carbon black, antioxidants and stabilisers.

Calendering and controlled cooling to ensure uniform thickness and crystallinity.

Surface texturing (optional) for improved interface friction on landfill slopes.

Material Characteristics & Index Properties

Tengeo geomembranes exhibit

High tensile strength & elongation (ASTM D6693)
Excellent puncture & tear resistance (ASTM D4833 / D1004)
Superior chemical & UV resistance
Exceptional stress-crack resistance (ASTM D5397 Notched Constant Tensile Load test)
Low hydraulic conductivity for barrier performance
Oxidative induction time (OIT) compliance for long-term durability

HDPE variants provide stiffness and chemical resistance ideal for landfills, while LLDPE variants offer flexibility for settlement-prone foundations.

Functions (Primary & Secondary)

Barrier containment—prevents liquid and gas migration
Environmental protection—isolates contaminants from soil & groundwater
Seepage control—water retention in reservoirs, ponds and canals
Slope stability—via textured geomembranes with enhanced friction
Integration with GCLs & drainage geocomposites for composite lining systems

Civil Engineering Applications

Tengeo geomembranes are used in

Municipal & hazardous landfill liners and caps
Leachate containment and drainage systems
Water reservoirs, irrigation ponds & farm ponds
Canal lining, check dams & aquaculture ponds
Industrial lagoons, mining heap-leach pads & ash disposal facilities
Tunnels, secondary containment basins & effluent storage
Floating or anchored cover systems
