Product Description

High Density Polyethylene (HDPE) popularity is primarily due to its low initial material cost and excellent UV & chemical resistance. This allows thicker sections of HDPE to be used in exposed applications where the cost of other materials may be prohibitive.  HDPE is a versatile material that is used widely across many applications. One of the primary uses of HDPE is as a liner at the base of landfills, where its chemical resistance is put to use. HDPE applications also include pond linings and water containment projects. HDPE is a field assembled lining material that cannot be practically fabricated in the shop. Therefore, all HDPE projects, regardless of size, must be installed by trained installers.

    Although it is preferable to avoid installing lining materials in cold temperatures, occasionally it can not be avoided. Cold weather usually requires a modification of installation techniques, or may involve substitution of materials to ones which have superior cold weather handling capabilities.

    Angle Bar Attachment 1

    Angle Bar Attachment 1

    An angle bar attachment is a standard attachment to concrete. The angle bar provides stiffness so that a compression seal can be made with the liner and gaskets. Angle bar can be attached at 300 mm (12″) centers which is more cost effective than the 150 mm (6″) centers required for flat bar.

    Liners are attached to clean, smooth concrete, using wedge anchors drilled into place. These wedge anchors are best placed during liner installation as it is very difficult to keep the concrete surface clean and smooth with cast-in-place anchors. The most difficult aspect of attaching liners to concrete is to obtain a smooth, clean surface.

    Exposed Vent Detail

    Exposed Vent Detail

    In certain circumstances gases can accumulate under a geomembrane and cause uplift. A gas venting system can prevent damage to the liner when uplift is predicted. A geo-net or geotextile vent layer is provided under the liner and up the slopes. At the top of the slopes a vent is provided to allow the gas to escape to atmosphere. The detail in this drawing shows a typical gas vent at the top of a slope in an exposed geomembrane. A drawing for a backfilled geomembrane vent is also available.

    Flat Bar Attachment 1

    Flat Bar Attachment 1

    A flat bar attachment is used when a low overall height is required, usually when the attachment is to be capped. Flat bar is also used to go around curves. Layfield normally uses an angle bar attachment for most work. Flat bar does not provide sufficient stiffness to make a permanent compression seal. Sponge neoprene gaskets, often specified with flat bar, do not normally provide long term compression. Usually only 50 to 60 durometer neoprene gaskets should be used. Flat bar is attached at 150 mm (6″) centers which normally costs more than the 300 mm (12″) centers required for angle bar.

    Liners are attached to clean, smooth concrete, using wedge anchors drilled into place. These wedge anchors are best placed during liner installation as it is very difficult to keep the concrete surface clean and smooth with cast-in-place anchors.
