Bontec HF

Woven geotextile for separation and filtration

HF woven geotextiles are an exclusive range of high-flow textiles with considerable mechanical strength and outstanding waterflow and pore size characteristics that will satisfy even the most demanding hydraulic applications. These products were developed for use in applications where a high permeability is critical together with a requirement for good filtration.

The HF (High Flow) range of geotextiles can be used as a filter wrap, an erosion control layer, a filter or separation layer or for load transfer. The geotextile will allow the passage of fluids without the uncontrolled passage of soil, as well as enabling the rapid removal of any excess water through its surface even in fine particle soils.


The HF range should be used where the rapid flow of water is critical and where reverse flows may be encountered. The unique characteristics of this high quality geotextile is down to its composition of polypropylene and polyethylene yarns.
