Usage & Purpose
Geocomposite for landfill cap drainage, gas-venting, ground water drainage and leachate management. Particularly useful on steep slopes where its core structure offers enhanced frictional performance, whilst providing protection to the lining system.
Pozidrain G is designed as a cost effective geocomposite for landfill cap drainage, gas-venting, ground water drainage and leachate management. It is particularly useful on steep slopes where its patented core structure offers enhanced frictional performance, whilst providing protection to the lining system.
Pozidrain G geocomposite has a lattice structure core which offers superior interface friction performance on steep slopes. This has been confirmed in a series of direct shear tests which compared the performance of Pozidrain G against other conventional geocomposites.
Results from these tests show the measured interface shear strength for the Pozidrain G4SD (4mm) geocomposite to be 20% stronger than the interface with other geocomposites. The results from tests on the 6mm and 7mm Pozidrain G interfaces show the increase in shear strength to be even greater.
Due to the manufacturing process and their permeable properties, ProFab® non-woven geotextiles are generally best used in applications of drainage, filtration and separation.
The patented core configuration in Pozidrain G geocomposite permits cross directional flow and helps mitigate the risk of system failure should the core sustain damage. Otherwise, this is a potential cause of soil saturation, leading to slope failure and is associated with products utilising drainage strips only.
Pozidrain GSD consists of a patented lattice, cuspated HDPE drainage core laminated between one or two layers of medium weight, non-woven filtration/protection geotextile.
The innovative use of a drainage lattice permits cross flow within the drainage composite. This offers significant advantages over other products that utilise drainage strips, rather than a lattice, within their composition. A further benefit is the lattice core prevents ‘torpedoing’; a problem with products based on strips which makes them difficult both to lay and to handle.
Using this core technology, Pozidrain G range offers engineers and contractors a high performance drainage solution with a combination of high-flow capacity, separation and reinforcement properties, helping address construction issues in many civil engineering applications.
