Global Synthetics geogrids are manufactured from the extrusion, weaving or welding of a polymer to form open aperture products of varying strength, strain and load carrying capability for applications of soil reinforcement.
Generally geogrids have a primary strength in one direction only (uniaxial geogrids) although in certain applications the strength may be equal in both directions of the product (biaxial geogrids).
Geogrids work by interlocking with the granular or soil material placed over them. The open apertures of the geogrid allows for confinement of the material within, thereby increasing the shear strength of such materials.
Geogrids are typically used in such markets as segmental block retaining walls, slope reinforcement, pile cap platforms and base reinforcement applications such as roads, carparks and rail line construction.
In applications of soil reinforcement and the use of geogrids in engineering structures such as slope stabilisation and segmental block retaining wall construction the geogrid to be used will be subject to constant load over long periods of time. The load will be exerted in one direction only i.e. at a normal direction to the structure face direction. Global Synthetics are able to offer ACEGrid® which is a uniaxial, polyester geogrid in a
range of strengths appropriate to this market segment and ensuring that the design strength of the geogrid may be maintained over very long periods of time (may be 100 years).
ACEGrid® has been exhaustively tested and used in a wide variety of soil reinforced structures throughout the world. Specifically ACEGrid® has been used in a significant number of structures throughout Australasia.
ACEGrid® is very easy to install and is available in wide width rolls to minimise wastage during installation.
A segmental block wall system was to be constructed to retain fill at the extremities of a proposed subdivision. ACEGrid® geogrid was used in conjunction with the block system to construct a soil reinforced wall.
