Uniaxial geogrid is a type of geogrid made from a single, linear network of polyester or polymers. It is designed to reinforce soil when stretched lengthwise along the sheet. This geogrid is commonly used in civil engineering applications such as reinforcing roads, walls, and embankments.
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.
