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.

Product Information
WASP 1800 Series LG Membrane
WASP Light Gauge membrane is a mono layer membrane specifically designed and manufactured to perform as a barrier system which is suitable for a variety of applications. This is a fully weldable, category 2 attenuation grade liner fully conformant to C753 and BS7533-13. This membrane will provide resistance to root penetration from invasive species.
WASP 1600 Series MG Membrane
WASP Medium Gauge membrane is a 0.75mm and most commonly specified as a water containment liner in the construction industry.
It is resistant to most chemicals, is extremely robust and has a high stress fracture resistance. WASP HD membrane is ideal for use in retention ponds, canals, ditches & water reservoirs.
WASP 1400 Series HG Membrane
WASP Heavy Gauge membrane is a 1mm thick and most commonly specified as a water containment liner in the construction industry. It is resistant to most chemicals, is extremely robust and has a high stress fracture resistance. WASP Heavy Gauge membrane is ideal for use in retention ponds, canals, ditches & water reservoirs.
WASP 1200 Series
FHD Membrane
WASP Flexible Heavy Duty Membrane is a 1mm thick robust weldable single layer cold applied geomembrane suitable for attenuation tank encapsulations, voided sub-base installations, lake / pond liners and containment. It is produced from a resin formulation designed to provide quality geomembrane with excellent flexibility, improved elasticity and resistance to puncture.
WASP 3100 Series
Infiltration Geotextile
WASP Infiltration Geotextile is a UV stabilised polypropylene continuous filament needle punched nonwoven geotextile. The mechanical properties guarantee excellent resistance to installation damage, excellent hydraulic properties and outstanding long term performance. It is ideal for use in permeable pavements as a separation layer or as the wrap to soakaways.
WASP02100 Series
HD Geotextile
WASP Heavy Duty Geotextile is a non-woven thermally bonded double sided geotextile, manufactured from UV stabilised, high tenacity, virgin polypropylene fibres that have been mechanically entangled to provide high strength, high extensibility, high loft and excellent abrasion characteristics. It has excellent resistance to installation damage, hydraulic properties and outstanding long term performance.
