GT 500 Attenuation Tank Liner

This product is shipped direct from the manufacturer: 2-3 day lead time.

GT 500 is a standard 2000 gauge impermeable membrane for lining / wrapping modular attenuation tanks. The attenuation liner is completely wrapped around the water storage tank to create a watertight skin. The wrapped tank should then be wrapped with an 300gsm protection fleece geotextile to prevent the tank liner being punctured.

All 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 perimetre of the seams.

Please note that for high capacity and high-flow applications, a thicker LLDPE geomembrane is usually required with the seams welded. See our product code GTLLDPE  for more information

You may want to consider a pre-fabricated shoe box liner depending on the size of your installation. A shoe box liner is an easy-to-install, pre-welded 2-part impermable box that does not require in-situ welding or specialist services.
