CeTeau Liners

  • 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. CeTeau offers a wide range of materials capable of meeting the ever increasing environmental demands.

  • Application
    • 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

  • Installation
    Geomembranes are heat welded in the field by certified technicians using the following welding systems;
    Hot wedge weld: a heated (metal) wedge is drawn between the liner, so that the material melts. By using pressure rolls the layers are converted to a homogeneous joint.
    Hot air weld: instead of using a wedge, the liner is heated with hot air and pressed together.
    Extrusion joints: a bead of melted HDPE is laid on the edge of the liner by using a hand extruder. This forms an excellent joint with the liner underneath.

    The large width (7.5 m) of CeTeau geomembranes reduces the number of welds considerably. To guarantee the quality of the welds, all welds are tested in the field.

  • High Density Polyethylene (HDPE) Geomembrance
    Polyethylene is a long-chain hydrocarbon thermoplastic material obtained through the polymerization of ethylene. 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. They are also very reliable in exposed environments due to their excellent resistance to brittleness in low temperatures and superior protection against UV degradation. Manufactured in wide rolls, polyethylene liners come in varying thicknesses ranging from 0.5 to 3.0 mm to meet engineering design requirements.

    Surface finish Polyethylene liners come in a variety of surface finishes, from smooth to heavily textured. Offering higher friction properties, textured materials are perfect for lining steep slopes to prevent the slippage of adjacent materials. The level of texturing is described by the asperity heights, which can reach up to 0.25 mm.

    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.

    LLDPE (linear low-density polyethylene) 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.
