Weaving high strength woven geotextiles
High Strength Woven Geotextiles are ideally suited for subgrade separation, reinforcement and applications where extremely high tensile strength with low elongation is required. Woven on Karl Mayer warp knitting machines, these high tenacity polyester yarns with high molecular weight are strong and creep resistant. The geotextile strength and polymer can be varied to suit particular applications. The influence of creep effects on varying polymer types is well understood and will have a marked influence on the load carrying capability of the geotextile selected.
Applications
A wide range of projects use high strength woven geotextiles including:
- Road & rail embankments
- Reinforced earth structures on poor foundations
- Slope stabilization
- Piled foundations
