Polyethylene geomembranes are used 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 to meet engineering design requirements.
Standard Thickness: From 20 to 120 mil (0.5 to 3.0 mm)
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 10 mil (0.25 mm)
HDPE (high-density polyethylene)
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.
LLDPE (linear low-density polyethylene)
As its name implies, linear low-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.
