Geogrids are used on civil engineering and road construction projects to provide strong and rot-free
sub base layers. For initial site access roads, or where the ground below has low or irregular load bearing capacity, or is sloping; a variety of different geogrids are available to reinforce the soil structure.
They have high tensile strength, so can tolerate a larger degree of compaction to the soils and aggregates placed above, thereby helping to create a harder, stronger upper layer. 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 and hardcore beneath; or hardcore, concrete and 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 and more cost effective installation of ground reinforcements.
Wallbarn can supply a large range of different geogrids; with thickness, material and mesh size depending on tensile strength, flexibility and filling material required.
Landfills & Reservoirs
For extra protection and water or vapour management in landfills and reservoirs, our mono-entangled mesh, with geotextile bonded each side can also be used.
This creates an additional filtration and water re-direction layer from above, placed above the waterproof membrane. Where it is laid on the horizontal surface to a fall, moisture will flow down through the geotextile and into the mesh, where it will form into droplets and run sideways into the drainage outlet.
Within a landfill, placed beneath the capping membrane, the mono-entangled mesh acts as an air gap, with vapour penetrating the geotextile (which prevents solids passing through) and flowing through the mesh structure sideways towards the vapour escape vent.
By using geogrids, contractors can ensure stable foundation layers use less fill material, smaller
excavations and have a longer design life, all of which lead to cost savings. For technical details on our products, please contact the sales team.
Wallbarn supplies a number of different types of geogrids designed to help soil filtration and stability for more heavy duty projects, such as road building, embankments, reservoirs and landfills.
