Uniaxial-geogrid has a high tensile strength and modulus( the ratio of stress to strain in a material under stress). Its tensile strength is 100-200 MPa, providing soil with an interlocking system for force bearing and diffusion.
Structure and functions:
Uniaxial geogrids are popularly made of high-density polyethylene (HDPE) with oblong hole meshes that are stretched and pressed into thin sheets. When laid in the soil, their interlocking effect creates an efficient stress transfer mechanism, allowing local loads to spread quickly and effectively over a larger area, reducing local damage stress and prolonging the project's service life.
Uniaxial mesh geogrid provides high tensile loads in one direction, can be used for the reinforcement of walls and slope.
Uniaxial Geogrids of HDPE Mesh
Uniaxial Geogrid of high density PE for soil reinforcement and paving overlay reinforcement, one-way tensile geogrid support for reinforced asphalt and cement pavement: Laying uni-axial geogrid on the bottom of asphalt or cement pavement can reduce rutting depth, increase the pavement's fatigue life, and also reduce the thickness of asphalt and cement pavement, leading to cost savings.

Application
Uniaxial Geogrid is commonly used in embankments, tunnels, docks, roads, railroads, construction, and other fields. Its primary functions are to strengthen the roadbed and effectively distribute diffuse loads, withstand heavier alternating loads, prevent deformation and cracking caused by roadbed material losses, increase the self-supporting capability of fills behind retaining walls, combine with spray-anchored concrete construction methods for slope maintenance (saving 30%-50% in investment and construction time), reduce bending and sinking of road bases and surfaces and delay crack formations (3-9 times), lessen structural layer thickness (up to 36%), and enable simple, fast construction (greatly reducing costs).
