WASP Geomembranes & Geotextiles

WASP geomembranes are robust weldable impermeable single layer cold applied geomembranes, suitable to form the water retaining encapsulation around an attenuation tank, to line permeable pavements where run-off is temporarily stored in voided sub-base layers or for pond liners and other water features. Geomembranes are available in different thicknesses to suit your application.

WASP geotextiles are available in either thermally bonded or needle punched formats. They are ideal for use as a protection layer, separation layer or for infiltration when encapsulating a soakaway or permeable liner where run-off is temporarily stored in voided sub-base layers prior to dispersal into the subgrade below.

Both WASP geomembranes and geotextiles can be supplied in a range of roll widths, roll lengths or panel pieces to satisfy your project requirements whilst minimising expenditure on surplus, unwanted waste material and reducing material to landfill. Health and Safety benefits of this tailored roll cutting service become apparent as rolls sizes and weights are better for handling and installation.

prefabricated shoebox membrane liners

Prefabricated Shoe-Box

SEL can supply prefabricated, flexible, welded attenuation tank liners and
lids; often referred to as “Shoe Box” Liners. These can be manufactured in
a variety of membrane types, with pipe connections to suit pipe all
diameters.

The liners are formed with heat sealed joints and supplied with
a lid that should be sealed in position once the attenuation crates are
installed inside. Jointing tape can be supplied to secure the lid in position.
The liners can be delivered directly to your site for convenience.
