Geogrids, Tensar Geogrids, Geogrid, Geogrid Technology

Farm Plastic Supply offers a full line of punched and drawn polypropylene geogrids. Geogrids can be used in base reinforcement applications to reduce aggregate base, extend roadway life, and reduce construction timelines. Punched and drawn geogrids offer superior junction strength and efficiency, thus achieving a more reliable aggregate interlock and stabilizing subbase sections more efficiently.

Our wide variety of Geogrids are strong and durable and are great for stabilizing soil and increasing its load-bearing capacity as well as improving its overall stability. We have a wide variety of Geogrids which include our Tensar NX850™ Geogrid and our Strata Grid 3 & 5 Series Geogrids.

    What are Geogrids?

    Geogrids are geosynthetic materials used for reinforcement and stabilizing soil structures. They have a very high tensile strength and a higher elastic modulus than soil, which allows them to distribute loads more effectively and evenly and provides better reinforcement in construction applications than they otherwise would. Geogrids can be used in soil reinforcement, reinforcement of retaining walls, slope stabilization, etc. Geogrids are formed by intersecting grids of elements extending in two directions, one in the machine direction (longitudinal) and the other in the transverse (or cross-machine) direction, forming the shape of the apertures. These apertures vary depending on application and manufacturer’s specifications. Geogrids are made of different materials such as polyester, polyvinyl alcohol, polyethylene, or polypropylene.

    How deep should geogrid be?

    For retaining walls take 10% of the wall height and bury it at that depth. For road stabilization, it is often a depth of 6″ to 12″. This is a general answer, always determine exact requirements from a civil engineer or the certified professional that is overseeing your project.

    When should you use a geogrid?

    Geogrids can be used in base reinforcement applications to reduce aggregate base, extend roadway life, and reduce construction timelines. Geogrid can also be used for any retaining walls over 6 feet in height. Geogrids are also great if you are putting a new driveway or gravel driveway or road. They are very versatile and can be used in many different circumstances.

    How are geogrids used as a soil reinforcement?

    Geogrids reinforce soil by interlocking granular material within their open, grid-like structure, which confines the soil particles and prevents lateral spreading under load. This process creates a more stable, unified mass that can withstand higher loads and distribute them over a wider area. This improves soil strength and reduces deformation. By providing tensile strength and stability, geogrids are used to construct durable retaining walls, reinforce roadbeds, stabilize slopes, and control erosion.

    Can you overlap Geogrids?

    With retaining walls you should avoid overlapping geogrid without following proper procedures for overlapping materials. There must be at least 3 inches of soil between geogrid layers to avoid movement between geogrid materials. With road stabilization projects you can overlap geogrid to accommodate wider roadways but only overlap 1 to 2 feet. Also, make sure the bulldozer blade avoids catching that overlap/centerline by pushing the aggregate the correct way across the overlap. This is a general answer, always determine exact requirements from a civil engineer.
