Geo-grid for reinforcement

The high tenacity polyester geo-grid; Betonap ® is manufactured with a unique technology called woven-knit-screening. This technology and the resulting high-tensile stiffness makes the geo-grid ideal for use with both structures and in earth stabilisation works.

Tension is uniform on installation with no rippling. This enables a direct correlation with the published criteria, with no compromise.

betonap features

The geo-grid creates good skin-friction with soils structure enabling a continuous anchorage to be mobilised. It will also vent hydro-static pressure helping to avoid the build up of water within ground or behind structures.

Durability: The results for Betonap ® after 10 000 hours of accelarated whole life testing at varying load coefficients are consistent with a durability of approximately 100 years. This assumes sustainability of the original design criteria on a given project.
