Applications
Nappe Solpac Lixiviat (Solpac Leachate Membrane) is a drainage geocomposite comprising a thermoformed HDPE geospacer with a symmetrical and impermeable cellular structure coupled with a geotextile woven into polypropylene strips.This type of product is designed to line the bottom of Landfill Sites in place of:
– some or all of the aggregate
– the geomembrane’s protective geotextile layer
The reduction in the volume of porous materials needed means an increase in the storage capacity of the cell, better drainage control, and savings on purchasing, logistics and implementation.
Advantages
- High flow rates that remain constant over the long term thanks to the elevated creep strength that is directly linked to the cellular design of the product
- Uniform flow over the entire surface and in every possible direction, irrespective of the direction in which the product is installed
- Hydraulic continuity is assured where two membranes are joined together
- Economic solution as they replace aggregate materials and protective geotextiles
- Greater landfill site waste capacity
- Wide geotextile filtration aperture and major reduction in the risk of clogging
- Easy and quick to install
- The large rolls lend themselves to fast, optimised installation over large areas
- High friction angle with the support layer thanks to the cellular structure. Reduced slippage risk
- Chemically inert
Materials: HDPE (geospacer) and PP (geotextile)
Thickness (geospacer): 6 mm
