Polyester Biaxial Geogrid
Coated high-tenacity polyester geogrid with equal strength both ways, for embankments over soft ground and heavy-duty base reinforcement.
Overview
Knitted from high-tenacity polyester yarn and coated in PVC, this grid has the same strength along and across the roll. Polyester stretches little and creeps slowly under sustained load, so the grid suits embankments on soft or variable ground, load-transfer platforms, and bases under heavy traffic where loads spread in every direction. The flexible rolls lie flat on uneven formation and are easy to cut and overlap.
Features
- Equal strength in both directions, from 40 to 200 kN/m
- Low elongation and low creep under sustained load
- PVC coating protects the yarns during installation
- Flexible rolls that follow uneven ground
- Rolls up to 5.95 m wide for fewer overlaps
