Geo-nets are another group of geo-synthetics that are produced and supplied from polymeric materials, such as grid lines. These products were initially developed in the United Kingdom for the transport of agricultural products in stores. Various experiments on this the products and especially the geometric shape of the grids and the thickness of the wires used in them showed that these products have a high drainage capability. As a consequence, the use of geo-nets in various developmental activities, especially drainage of the soil became commonplace. Due to the drainage potential on their pages, they have the same property as other geo-synthetics geo-grid, geo-textile or geo-membrane used in civil affairs.
Geo-nets are usually used in conjunction with other geo-synthetics, such as geo-textiles or geo-grids. The use of geo-textiles in top and bottom of geo-nets causes to prevent the entry of particles and soil grains into geo-stained portions and guarantee the vents aren't blocked applications of geo-nets.
Usage of geo-nets:
1- Drainage of water behind the retaining walls and other technical buildings in roads and airports and railways
2. Water drainage in the gutter
3. Water drainage in rocks of building foundations
4. Water drainage in soils with freezing potential
5. Drainage of water in different layers of roads, airports, and railways
6. Water drainage below the sports fields
7. Drainage leakage of the gutter sides of the landfill site
8-Drainage on top of the waste landfill place
9-Drainage of leakage material between two sheets of the landfill (seated tracker)
10-Drainage of surface water in the closure of waste landfills
11-As a drain cover underneath an embankment layer
