Biaxial Geogrids provide omni axial support to granular sub bases and areas of weak or varied soils. These biaxial geogrids ensure any problems with pavements are solved by reinforcing capping layers and railway ballasts. These layers are reinforced with granular particles compacted over the grids, which penetrate and project through the apertures to create a strong interlock. An exceptionally minimal maintenance system the biaxial geotextile is a cost-effective solution for pavement problems.

Applications
In the construction of port breakwater and cofferdam, the first problem to be solved is soft soil foundation. The soft soil foundation is usually treated by a combination of sand cushion and plastic drainage board, but due to the heavy load on the upper part, the uneven settlement and slip can be caused. Laying Geogrid 120 and filament non woven geogextile at the bottom will increase friction, reinforce subgrade and soft soil, greatly preventing uneven settlement and sliding movement, which plays an important role in increasing the overall stability of the port dam.
