Bontec® SG

Woven geotextile for separation and reinforcement

Bontec woven geotextiles offer the perfect cost-effective solution for separation, reinforcement and filtration. Bontec woven geotextiles are manufactured from polypropylene tapes.

Bontec SG is used in areas such as access roads and hard standings, roadways, car parks and coastal defence projects. One of its primary uses is in separation applications where there is a requirement to prevent intermixing of soft in-situ soils with good clean granular fill. A range of aperture sizes is available for Bontec SG woven geotextiles.

Compared to nonwovens, the Bontec SG range shows a greater mechanical strength per unit weight, providing a cost efficient and reliable solution for roads and temporary access roads.
