Geotextile Underlay


Every ClearWater Tank comes standard with Geotextile Underlay …  a non-woven, needle-punched geotextile made from polyester.

Our underlay is manufactured for pavement stabilisation, subgrade / subsoil separation, slope stabilisation and liner protection. The underlay functions as reinforcement to protect your liner.

The natural UV resistance of polyester ensures the material can withstand harsh Australian environments. The geotextile underlay provides superior technical performance.

Due to high levels of elongation, the product will adapt to deformations within the sub-base reducing the risk of damage to your liner during installation and into the future.
