Drainage Protection is a drainage geocomposite comprising a symmetrical thermoformed cellular High Density Polyethylene (HDPE) geospacer core coupled with non-woven polypropylene filters that fulfils the following functions:
it protects the damp course layers and treatments from mechanical damage, which is particularly important during backfilling
it maintains a thin cushion of air along the buried walls, allowing the water absorbed by the foundations (due to capillary attraction) to evaporate
it isolates buried walls from the damp ground thanks to its impermeable structure
it intercepts and evacuates seepage and ground water.

Materials: HDPE (geospacer) & PP (geotextile)
Thickness (geospacer): 8 mm
Standards: NF EN ISO 9863-1
NF EN ISO 25619-2
NF EN ISO 12958
