Geo-straps comprise of tendons made from high tenacity polyester yarns concentrated in ten separated bundles and encased in a durable polyethylene sheath. The polyester yarns are placed in tension and polyethylene is then co-extruded on to the polyester to form polymeric strap. While polyester is load-bearing element, polyethylene sheath protects the polyester yarns and provides the size and shape to the straps.

Geostrap is supplied in various strengths between 30 to 100 kN. The width of Geo-strap varies between 85 to 90 mm depending on the strength.
