Polyfelt® DC
Polyfelt DC is a geocomposite consisting of a geonet and a filter nonwoven on one or on both sides. The geonet is made from high density polyethylene (HDPE), the filter nonwoven consists of polypropylene (PP). Polyfelt DC is characterised by low compressibility, and is therefore used in situations where effective drainage under high overburden pressures is required.
