Geogrid Suppliers
Manufacturer and distributor of geosynthetic materials including geogrids. Products are chemical, UV and weather resistant and meet ASTM standards. Typical uses include base stabilisation and slope reinforcement.
Using a geogrid speeds up construction and reduces your overall project costs. They are made from polymer material that can be extruded, knitted or woven and heat-welded into grid structures. They have high tensile strength in both machine and transverse directions and strong junctions.

Polypropylene, polyester, polyvinyl alcohol and polyethylene are common materials used to make geogrids. They can be woven or knitted from yarns, heat-welded from strips of material, or made by punching a regular pattern into sheets of the material that are then stretched into a grid. They have high tensile strength, which means they hold together better than soil under stress, and are very resistant to strain, creep and natural chemicals.
Geogrids can be woven into a variety of applications, including retaining walls, steep slopes, highways and railroad embankments. They can also be used to support paving overlays. They can help to prevent the surface from cracking, and they also help to reduce the time it takes for a paving crew to install the asphalt.
Uniaxial geogrids have their tensile strength in the machine (roll) direction and are mainly used to reinforce the soil mass in a segmental retaining wall or steepened slope. They can also function as a wrapping to confine the aggregate in the wire forms of welded wire faced steepened slopes. Woven or knitted uniaxial geogrids are made from polyester industrial yarns and have a PVC or polymeric coating to protect them from biological degradation and resist strain, creep and natural chemicals.
Types
A geogrid’s characteristics are determined by the process used to manufacture it. The material can be woven or knitted, or made by heat-welding strips of polymer plastic to create a grid structure. The fabric’s thickness is an important factor in determining its performance, and the geometry of the ribs and junctions is also crucial. Creep strain, tensile modulus, junction strength, and flexural rigidity are also critical parameters.
Geogrids are available in uniaxial, biaxial, and triaxial configurations, each with its own specific strengths and properties. For instance, biaxial geogrids have greater strength in two directions compared to uniaxial ones. This characteristic allows designers to choose the best geogrid for the project they are working on, depending on its intended application.
One of the most common uses composites drainage network for geogrids is soil reinforcement. They help to stabilise and strengthen soil and similar materials, providing a solid base for construction. In addition, they increase the load distribution angle under roads and pavements, which reduces environmental cracking and other problems.
Roadways often need thick bases to support the loads they are designed to carry. However, increasing the thickness of the base is costly and time consuming. Installing geogrids under the roadway can significantly improve its stiffness, allowing it to carry more traffic and prolonging its service life. Geogrids are also used in slope and earth embankment reinforcement, soil stabilization, turf reinforcement, revegetation, and containment.
Applications
A variety of applications exist for geogrids, including retaining walls and embankment stabilization. These products help reduce project costs and schedules while increasing the structural integrity of structures built over soft soils. They also increase load-bearing capacity and decrease differential settlement.
The most common geogrids are extruded and come in uniaxial or biaxial designs. Uniaxial geogrids are oriented along the longitudinal, machine direction of an extruded sheet of polymer and have long, narrow ribs. These types of geogrids typically offer high allowable strengths at deficient strains and can be used in a wide range of wall and slope applications. Woven geogrids are a more flexible, textile-like alternative to extruded products. They are woven from polyester or polypropylene yarns and have flexible junctions that form apertures. They are available in both biaxial and uniaxial versions and can be given a protective coating of bitumen, latex, or PVC.
The aperture size and shape of a geogrid heavily influences its mechanical behavior and characteristics. For example, a study demonstrated that the smaller the aperture size of a geogrid, the less it interlocks with the soil. This causes lower pullout resistance and can lead to dislocation of the geogrid from the soil. Additionally, the shape of the ribs and junctions of the geogrid can influence its strength. Testing techniques like the uniaxial constant rate of strain (CRS) test and biaxial tensile tests have been shown to better capture the strength properties of geogrids than the conventional tension test.
