Polyester Uniaxial Geogrid
High-tenacity polyester geogrid with its strength in one direction, for reinforced soil walls, steep slopes and embankments on soft ground.
Overview
Warp-knitted from high-tenacity polyester yarn and protected with a polymer coating, this geogrid carries its strength along the roll direction. It combines high tensile capacity with low elongation under sustained load, which is what reinforced soil walls, steep slopes and basal reinforcement of embankments need. The coating shields the yarns from installation damage and from the chemistry of the fill.
Features
- High tensile strength along the roll, from 50 to 200 kN/m
- Low elongation and low creep under sustained load
- Polymer coating protects the yarns during installation
- Resistant to biological degradation in the soil
- Flexible rolls that follow the contour of the ground
