Abgrid biaxial geogrid can be used in a wide range of civil engineering applications such as basal reinforcement, ground stabilisation, aggregate reduction, piling platforms and foundation engineering for paved and unpaved roads and temporary works.
Grid structure provides soil reinforcement for all civil engineering projects including environmental and infrastructure applications.
Abgrid geogrid is manufactured from extruded polypropylene which is then punched and drawn to form a monolithic geogrid with strength in two planes (biaxial). Abgrid biaxial grid is manufactured to have equal or similar tensile strength in both perpendicular directions (the longitudinal and transverse axes). It is primarily used for ground stabilisation, subgrade reinforcement and distributing dynamic loads across broader areas.
The combination of ribs and the corresponding nodes within the geogrid allows loads to be transferred into the geogrid structure, whilst allowing a positive interlock of the reinforced materials through the apertures of the geogrid. When granular materials (like gravel or crushed stone) are compacted over the grid, the particles project through the square apertures, creating a mechanical interlock.
Abgrid biaxial geogrid offers high tensile stiffness at low strains, combined with excellent resistance against damage occurring to the geogrid during the construction process or from environmental exposure. The stiff structure of the grid spreads the weight of heavy, moving loads (such as HGVs or heavy traffic) across a wider surface area and restricts the lateral movement of subgrade and base soils, preventing rutting and foundation settlement.
Abgrid biaxial geogrid offers savings across the project and is quick and simple to install. The use of Abgrid geogrid also facilitates a reduction in the required fill, and by stabilising the granular layers the sub-base can often be reduced without compromising load-bearing capacity.
