Polyfelt® Drainage composites
TenCate Polyfelt® DC is a drainage composite consisting of a geonet bonded with nonwoven geotextiles on one or on both sides of the geonet offering a combination of drainage and filtration functions. The geonet is made from high density polyethylene (HDPE) while the nonwoven filter geotextile consists of polypropylene.
TenCate Polyfelt® DC is characterised by low compressibility, and is therefore used in situations where effective drainage under high overburden pressures is required.
Benefits of TenCate Polyfelt® DC drainage composites:
- Reduced space requirements and excavation costs
- Controlled quality
- High compression resistance
- High chemical resistance
- Ease of installation
- Significant time and cost savings
Functionalities of Polyfelt® DC

Drainage
The major function of draining is to evacuate water or other liquids towards the structure’s outlets.

Filtration
The equilibrium soil-to-geotextile system that allows for adequate movement of a liquid across the plane of the geotextile to prevent clogging and limit soil loss over the service lifetime of the application.
Typical Applications of Polyfelt® DC
