AGRU America’s Drain Liner geomembrane can be manufactured with either high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). Drain Liner is best suited for single- or doublelined projects such as landfills, waste ponds, lagoons, mining heap leach pads, and process ponds where containment and leak detection is crucial. Drain Liner eliminates the need for a separate geonet drainage layer, providing cost savings in material usage and installation.
Manufactured using a flat-die cast extrusion process, as opposed to blown film extrusion, Drain Liner features consistent stud pattern and spacing, which gives the liner high flow rates and reliable drain capacity. The stud pattern also reduces the potential for chemical and biological clogging by allowing freer flow of liquids. Integration of the drainage layer with the liner sheet removes a typically problematic interface in veneer stability design. Finally, the product’s smooth edges allow fusion welds between adjacent sheets, and a special cutting tool can remove studs from cross seams as needed prior to welding.
AGRU fully integrates Drain Liner’s studs into the liner in one production step, eliminating the risk of separation during use. By combining separate components into a single product, designers are able to meet multiple needs during a single installation, reducing overall installation time and lowering material and CQA costs.
Manufactured using a flat cast extrusion process, as opposed to blown film extrusion, Drain Liner has consistent core thickness and high tensile strength. Its studs are fully integrated with the liner in one production step, leaving no risk of separation during use. These traits make the Drain Liner an effective Integrated Drainage System (IDS), with significant advantages over conventional geonets.
One-layer installment as an integral drain with the primary or secondary liner, depending on installation. This reduces installation time dramatically and lowers material, installation and CQA costs. It also provides better consistency and a bi-directional flow.
