Polyethylene geomembranes were developed exclusively to reduce the hydraulic conductivity of earthworks and are part of one of the most sophisticated and effective impervious systems known to date. Geomembranes are widely used for containment of liquids, solids and waste materials by virtue of its characteristics; resistance to a wide range of chemicals, reliable in exposed environments due to high UV protection against degrading and low temperature brittleness. GTEK offers a wide range of materials capable of meeting the ever increasing environmental demands.

  • Landfill liners and caps reservoirs, irrigation canals, industrial ponds and lagoons
  • Recreational lakes, ponds and golf courses
  • Agriculture, shrimp farming
  • Mine tailings & heap leach pads
  • Secondary containment of storage tanks
  • Floating covers

High Density Polyethylene (HDPE) Geomembrane HDPE (high-density polyethylene) is the most chemically resistant member of the polyethylene family on account of its dense configuration (>0.94 g/cm3). It is extensively used for containment structures. Although less flexible than its LLDPE counterpart, it still offers great elongation properties allowing up to 12% deformation at its yield point.

Linear Low-density Polyethylene (LLDPE) Geomembrane LLDPE as its name implies, is a lower-density polyethylene is a lower-density polymer (<0.939 g/cm3) yielding increased material flexibility. LLDPE is mainly used where long-term large settlements are anticipated such as landfill covers.

Our geomembrane are available in the following range; Thickness: 0.5 to 3.0 mm Finishes: Single-side texture Double side texture Color: Black, White, Green, Tan

Geotextiles have secured a valued and permanent place among construction materials in civil engineering by providing major contributions towards increased efficiency and economy in all facets of construction.The wide range of woven and non-woven geotextile products are used worldwide in the building industry, landscaping and civil engineering for erosion control, drainage, soil reinforcement, stabilization and consolidation and for special applications in waste containment.

Our Geotextiles are available in the following range; Nonwoven: 100 to 1,200 gram/m2 Woven: 40 to 400 KN/m

Specifications are available upon request.


  • CSeparation/reinforcement layer in foundations for motorways, airports, railroads
  • Filter material for drainage systems, bank and slope protection, erosion control,
  • Protection layer for waste depots, tank storage, canal lining and irrigation basins,
  • Reinforcement or soil stabilization of soft areas and marine workss

Geosynthetic clay liners (GCL)

Geosynthetic clay liners are high-performance environmental liners comprised of geotextile - or geomembrane-carrier component bonded to a layer of low-permeable sodium bentonite. Our 6mm GCLs provide better engineered hydraulic performance than one meter of compacted clay. With the self-sealing property and normal overlapped seam, cost-effective installation makes GCL the superior choice for a wide range of applications.


  • Composite landfill liners and cap
  • Ponds
  • Water work
  • Industrial surface enclosures
  • Ground water protection
  • Stormwater and waste water retentions

HDPE E-Lock Concrete Profiles

Securing geomembrane liner to concrete structures can be carried out either by mechanical fastening (using stainless steel flat bar, neoprene sponge and anchor bolts) method or by embedding E-Lock into concrete and geomembrane liner is then welded onto the exposed surface of E-Lock using extrusion welding method.

GTEK Resources produces E-lock in different shapes and custom length to suit the actual project requirement.

All E-lock are made from virgin HDPE resin with 2 to 3% carbon black content. E-lock are made from the grade of resin normally used by major geomembrane manufacturers for make HDPE geomembrane liner.

The advantages of using E-lock against mechanical fastening are cheaper in cost, easier to install and more secured.

Stormwater module tank system

Stormwater modules or also known as modular rainwater storage systems, provide underground storage for runoff. They can be used in detention, infiltration, and rainwater harvesting applications.The system is an alternative to stormwater basins and a more efficient, space saving alternative to other underground systems. After a rain event fills the tank system, stormwater can flow into the drainage system, infiltrate into the ground, or be reused.

Modular Tank System has unique advantages, such as high compressive strength allows to be used under trafficable areas, interlock system that maximize stability and installation, less costly than concrete and metal storage systems, low storage and transportation cost, and it caters for all volume requirements. Overall, modular rainwater storage system is effective and versatile for water storage.


  • High compressive strength allows use under trafficable areas
  • Interlocks vertically and horizontally for maximum stability
  • Less costly than concrete and metal storage systems
  • Caters for all volume requirements
  • Easy assembly of panels and installation of units
  • No surface water storage hazards
