Description
The Geoworks HDPE 0.6mm Impermeable Geomembrane is a premium high-density polyethylene liner designed to provide a durable waterproof barrier for demanding civil engineering, infrastructure and construction projects.
Widely specified for attenuation tank encapsulation and Sustainable Drainage Systems (SuDS), the membrane creates an impermeable lining around stormwater storage systems where water retention is required. Its fully weldable construction enables secure watertight joints, while the generous 5.1m width helps reduce the number of seams, improving installation efficiency on larger projects.
In addition to attenuation tanks, this geomembrane is suitable for ponds, lagoons, waterproofing, hydrocarbon containment, root barriers and other containment applications requiring long-term durability and excellent chemical resistance.
For optimum performance, the membrane is typically used alongside 300gsm non-woven protection fleece, double-sided butyl jointing tape, single-sided jointing tape and top hat units for sealing around pipe penetrations.

Recommended Accessories
For a complete attenuation tank lining system, we recommend pairing this geomembrane with:
What is this geomembrane used for?
It is commonly used for attenuation tank encapsulation, SuDS, stormwater storage, waterproofing, ponds, lagoons and containment systems.
Why choose the 5.1m wide roll?
The wider roll reduces the number of joints required on large installations, helping speed up installation and minimise potential seam locations.
Can the membrane be welded?
Yes. It is fully weldable, making it suitable for creating secure impermeable lining systems.
Do I need protection fleece?
For attenuation tank encapsulation and similar applications, 300gsm non-woven protection fleece is recommended to help protect the membrane during installation and backfilling.
Is there a smaller roll available?
Yes. A 2.5m x 50m version is available for projects where a smaller, easier-to-handle roll is more appropriate.
