Roll Size: 4m W x 12.5m L
2000 Gauge / 500mu

This high quality impermeable geotextile membrane is manufactured from virgin polymer for use with Attenuation Tanks to prevent flooding. Not for use with soakaway crates as part of a soakaway system.

The seams should be double-sealed using 50mm double-sided butyl tape between the layers of membrane and a 75mm single-sided butyl tape around the perimeter of the seams.

Please note that for larger higher capacity attenuation systems then a thicker grade of liner would be required, usually at least 1mm thick. We do not stock this membrane, but we can have it made up for you in what’s called a “shoe box” liner, which is an easy to install pre-fabricated liner. We can quote for this on request, please contact us for more information.
