A strong support system is required while constructing roads in heavily trafficked areas, for example, parking spaces. These structures must have a maximum bearing capacity.
For this purpose, geogrids are installed in the middle of the base course and the subsoil. Geogrids are made up of flat bars and have durable welded junctions that are able to withstand a massive amount of pressure.
The soil is able to interlock with the efficiently designed geogrids, which develops a strong bond. Due to this interlocking, a horizontal force transfer occurs which dramatically expands the soil’s bearing capacity.
Even with low elongation, a significant amount of force is absorbed by the geogrids, improving the capacity.
If a structure needs a specific bearing capacity value, it can be achieved by adding multiple geogrids. It is a very cost-efficient way because you do not have to spend on expensive soil exchanges.
Geogrids and non-woven geotextile material are extensively used in Malaysian construction projects to act as an excellent filter. They impede the migration of small particles into the base course.
Many suppliers also combine geogrids and woven geotextile to create a combined product that will support the construction and improve bearing capacity. Multiple layers of geogrids should be used in areas where the soil is extremely soft.
