Leachate Collection and Removal System

Leachate Collection and Removal Cover

TenCate Polyfelt® DN geonets are made from HDPE to form three-dimensional channels that provide high flow drainage capacity. TenCate Polyfelt® DN geonet when bonded with nonwoven geotextiles either on one side or both sides of the geonet provide a drainage composite, TenCate Polyfelt® DC, which offers a combination of drainage and filtration functions. TenCate Polyfelt® DN and TenCate Polyfelt® DC are ideal for transmitting fluid in applications such as behind retaining walls, landfill design as leachate or gas drainage layer, sport fields, garden landscapes, and below slab water pressure release. The benefits of TenCate Polyfelt® DN and TenCate Polyfelt® DC over conventional drainage aggregates are less potential to clogging, easy to construct and low cost especially when aggregates are scarce.

In applications where the normal load is high, TenCate Polyfelt® DF is ideal due to its high compressive strength and its ability to maintain high in-plane water flow under pressure.
