What is Geogrid Used for?
Geogrid is a type of geosynthetic material, which is designed to reinforcement and stability improvement. Whether used for road, railway, embankment or retaining wall, geogrid can offer safer and longer-lasting solutions.
How is Geogrid Formed?
The shape of geogrids is generally a mesh-type sheet formed by polymer ribs in different directions. On the production line, a complete and thick-pored polymer sheet will be stretched along one or two intersecting axis directions under the machine, with the middle holes being pulled to become larger, forming a geogrid with evenly distributed ribs and holes.
How Dose Geogrid Work?
Geogrid presents a crisscrossed grid rib pattern on the horizontal plane. Its grid structure can fill engineering materials or backfill soil. These materials, confined by the grid, become more stable and less prone to sliding, which ensures a balanced proportion of filling materials per unit area of the entire foundation or road surface. This structure can evenly distribute the road load, greatly enhance the service life of various road surfaces and reduce the risk of cracking or collapse.
What Are Geogrids Used For?
-
Roads, Highway, Expressway and Pavements
Installed beneath various road bases to reduce rutting and extend their lives.
-
Slopes and Embankments
Holding soil in place to prevent erosion and reduce the risk of landslides.
-
Retaining Walls
Reinforce soil behind retaining walls to allow walls to be built higher with less material for maintaining
-
Railway
Strengthening the substructure to ensure smoother operation and reduce maintenance costs.
-
Landfills and Environmental Projects
Used as lining systems, capping layers and erosion control for environmentally sensitive projects.
Types of Geogrids
Geogrids come in different types, each designed for specific applications:
-
Uniaxial Stretch Geogrid
It is stretched in one direction and provide strength primarily along the roll length. Thus, it is commonly used for retaining walls, steep slopes and embankment reinforcement where strength in a single direction is critical.
-
Biaxial Stretch Geogrid
It is stretched in both directions and provide balanced strength in two axes. It is ideal solution for soil stabilization under roads, parking lots and foundations where loads come from multiple directions.

Nowadays, geogrids have become an essential geosynthetic material. Thanks to their excellent physical structure, our projects become more economical and more sustainable. Among them, uniaxial and biaxial stretch geogrids are commonly used as two of the best solutions. According to different construction environments, we can choose proper geogrid to ensure the safety and durability of projects.
