Geogrid for Retaining Walls



Geogrid for Retaining Walls is the ideal solution for stabilizing the soil behind structural retaining walls.

This geogrid is engineered for durability and is made of a woven multifilament polyester mesh, each fiber is reinforced with coated PVC plastic.  This mesh confines gravel and aggregate soil in the grid holes to limit the lateral shifting of rock and soil. By limiting horizontal soil movement, the grid acts to reduce the soil from collapsing and enables larger structures to be built.

Uniaxial and Biaxial geogrids are both commonly used by contractors, homeowners, and municipalities for retaining wall projects all over the USA.

3 Series – For wall applications up to 10 ft in height

5 Series – For wall applications over 10 ft in height

Utilizing Geogrid in a Retaining Wall Installation

Retaining walls are designed for landscaping and civil engineering to hold back soil and stop erosion. These structures are used in many different applications such as home gardens and large infrastructure projects. To increase the stability and longevity of these walls, geogrids are the chosen product.

In this article, we will go over the benefits of using geogrids, choosing the right geogrid for your project, and how to install and maintain geogrid-reinforced retaining walls.

About Geogrids

Made from geosynthetic materials, geogrids reinforce soils and other similar materials. Geogrids are made from polymers such as high-density polyethylene (HDPE), polypropylene, or polyester. Geogrids are designed in a grid-like pattern with openings or spaces allowing soil particles to interlock for reinforcement and stability in the soil structure.

The Benefits Of Using Geogrids

Increased Stability And Load-Bearing Capacity: Geogrids are the chosen product for stabilizing and providing load-bearing sizes of retaining walls. By reinforcing the soil, geogrids distribute loads more evenly. Geogrids will reduce the chances of wall failure and the movement of soil.

Save On Costs: Geogrids will cut back on the cost of fill material and allow for steeper wall designs by cutting construction costs. The increased stability offered by geogrids will lower the need for maintenance and repairs, giving you savings in cost over time.

Adaptability: Geogrids are a popular choice for different kinds of retaining walls including gravity walls, reinforced soil walls, and hybrid systems. This is a great product for both residential and commercial projects.

Improved Appearance: Designing steeper walls that blend in with the surrounding landscape, and geogrids can increase the attraction of retaining walls. This is significant in residential and public places where appearance is important.

Environmental Benefits: Geogrids will reduce environmental impacts caused by the construction of retaining walls because they require less concrete and other materials. Geogrid is a more sustainable approach for soil reinforcement.

Selecting The Right Geogrid

Selecting the right geogrid for your project requires several ingredients:

The Kind Of Geogrid: There are three kinds of geogrids - uniaxial, biaxial, and triaxial. Uniaxial geogrids are created to bear loads in one direction and are used for retaining walls. Biaxial and Triaxial geogrids offer reinforcement in many directions and are used in road construction and stabilizing the ground.

Materials: Because geogrids are made from different materials including HDPE, polyester, and polypropylene, each has different properties such as tensile strength, durability, and resistance to chemicals. Know the requirements of your project before choosing the material.

Opening Size: The size of the opening in the geogrid will affect how well soil particles interlock. The larger openings are good for ground with coarse soils. While smaller openings are best for fine-grained soils. Make sure the opening is the right size for the kind of soil you are working with.

Tensile Strength: The tensile strength will dictate the geogrid's ability to bear loads and reinforce the soil. Make sure to select a geogrid with sufficient tensile strength to meet the requirements of your project.

Maintaining The Reinforced Retaining Wall

Regular maintenance is important for the longevity and overall performance of the retaining wall. Follow these steps:

Inspect Regularly: Regularly inspect the wall for any signs of cracking, movement, or erosion. Early detection of issues will give you plenty of time to make repairs and prevent further damage

Drainage Inspection: Drainage is critical for the stability of the retaining wall. Check to ensure the drainage system is operating properly. Check the weep holes and drainage pipes ensuring they are operating properly and are free of blockage. If you find any issues affecting proper drainage, immediately make repairs

Retaining Wall Construction

Control Vegetation: Keep an eye out for vegetation growing near the retaining wall and prevent the growth of roots that could harm the wall. Remove any plants or trees that could add pressure to the wall or unsettle the backfill material.

Make Repairs: If you notice any damage like displaced wall units or geogrid damage, make repairs immediately. Follow up by checking to ensure the repairs are working.

Case Studies

One: Residential Retaining Wall:

The homeowner was faced with soil erosion on a sloped area of the property leading the owner to invest in a retaining wall. Using uniaxial geogrids, he was able to build a stable and visually attractive wall that successfully held back the soil. Geogrids offered the mandatory reinforcement by allowing for a steeper wall design and reducing the amount of backfill material required.

Two: Commercial Development Project: During a commercial development project, it was determined they needed a large retaining wall to create level building pads on the sloped site. Using geogrids in the retaining wall design would allow for the construction of a tall and stable wall. The geogrid-reinforced wall offered the required support for heavy loads required by the buildings for long-term stability while reducing maintenance costs.

Three: Infrastructure Project:

Geogrids were used to reinforce the retaining wall running along the road embankments. The geogrid-reinforced walls offered excellent stability along with load distribution in order to reduce the risk of wall movement and erosion. Using geogrids allowed for faster construction and reduced material costs, contributing to the overall efficiency of the project.

In Conclusion

Geogrids are adaptable and an effective solution for increasing the stability and longevity of retaining walls. Enforcing the soil and evenly distributing loads, geogrids helped prevent wall failure and reduced the need for extensive maintenance and repairs. When selecting geogrids, consider the kind of geogrid, the material, the opening size, and tensile strength to ensure you have the best product for your project.
