A new non-woven geotextile from geosynthetics specialist Terram aims to safeguard impermeable pond and attenuation tank liners to help ensure long-term system integrity and reliability.
The primary function of Terram Pond Liner Protection Geotextile (PPG) is to provide a robust, protective layer between the pond liner and the underlying soil or substrate – helping prevent punctures, tears and damage during installation and throughout the pond’s lifetime.
Made from UV-stabilised, high tenacity virgin polypropylene fibres, Terram PPG is mechanically and thermally bonded to deliver more strength and durability. “Its advanced production process results in a more malleable material than standard geotextiles, making it ideal for complex pond and tank installations,” the manufacturer states.
“Terram PPG is designed to be the first line of defence for critical containment systems,” said Adam Brooksbank, national sales manager. “It offers superior protection against punctures and tears, helping to extend the life of pond liners and reduce maintenance costs.”
Key applications include protecting geomembranes or other impermeable membranes, separating pond liner from subgrade soils to avoid damage and protecting attenuation tank impermeable membranes to avoid damage to the membrane during backfill.
The randomly oriented web design provides “consistent strength and performance in all directions, and high elongation at break maintains separation function under load”.
Lightweight and easy to handle, the geotextile helps cut install time and labour costs, Terram adds.
