Woven Geoflax geotextile
Woven geotextile is formed by directly weaving polyolefin strips produced by cutting extruded ribbons. Due to its structure, woven geotextile provides reliable separation of layered materials, and due to its composition, it is resistant to chemical and biological environmental exposure.
It can be used on limestone, karst or alkaline, clay soils. The reinforcing properties of the interweaving thread method used in woven geotextile allow using hardly suitable soils for earth foundation, motor and rail road embankments.
Advantages of woven Geoflax geotextile:
1. Compared to the non-woven geotextile, woven geotextile has higher strength and smaller elongation at break, which allows the material to take the loads faster.
2. Due to the uniform distribution of a load over the web surface, woven geotextile contributes to better strength, higher shear resistance of layers and has proven itself as a reinforcing material for soft bases.
