Installation
Infiltration/Soakaway Applications
For soakaway applications we provide woven and non-woven geotextiles. These offer high permeability and strength, ideal for infiltration crates.
See Road Building section for our full range of geotextiles.
Attenuation/Storage Applications
For storage applications we offer impermeable polyethylene membranes in a roll form along with joining tapes and top hat pipe seals to enable sealing of pipe inlet/outlet junctions with storage tank. Together with needle punched Fibre (non-woven) geotextile protection fleece to minimise risk of puncture to impermeable membrane from sharps in backfill material.
Installation Guide
If a fully welded system is required we can supply materials and labour to site. The contractor shall excavate the hole whilst our fully approved installer will install the crates, geotextile protection fleece, and impermeable membrane with fully welded seams (any membrane thickness from 0.75mm to 2mm is available) and securely welded pipe entries and vent pipes. The contractor is then left to backfill around tank.
