Geogrids are used on civil engineering & road construction projects to provide strong & rot-free sub base layers.

Geogrids belong to geosynthetics materials that fulfil a reinforcing function in a ground structure. They are formed by a flat polymer structure, namely by a system of mutually perpendicular longitudinal & cross drawn elements which can be bonded continually by weaving, welding, gluing or binding in the points of intersection thus usually creating apertures with sizes between 1 and 10 cm.

This allows penetration of particles of soil/rock or other geotechnical materials through mesh apertures and formation of particle interlocking. It is good for this reinforcing particle interlocking effect when the grains are able to push through the mesh with at least a half of their volume into the substrate layer.

Geogrids have high tensile strength, which means that they are able to tolerate a larger degree of compaction to the soils & aggregates placed above, this means that a harder & stronger upper layer will be created. The net shaped grids help to hold the filling material together (on horizontal and sloping surfaces) which prevents erosion of the fill material above and subsidence of the soil below.

They can be used on many types of filling material – be that crushed earth & hardcore beneath; or hardcore, concrete & tarmac on top. By using geogrids, contractors can build base reinforcements in areas where traditional earth structures would be difficult; such as moorland and waterlogged land, steep slopes and soft ground.
Geogrids lead to easier, faster & more cost effective installation of ground reinforcements.

Wallbarn can supply a large range of different geogrids; with thickness, material & mesh size depending on tensile strength, flexibility and filling material required.
