Geogrid Reinforced Retaining Walls
Geogrid reinforced retaining walls are strategically engineered and comprised of:
- Geogrid reinforcement material
- MagnumStone concrete retaining wall blocks
- Reinforced engineered soils
- Effective drainage channels
Advantages of Geogrid Retaining Walls
Less Geogrid Layers, More MagnumStone Geogrid Strength
Our 2 feet tall (0.61 m.) standard blocks require less layers compared to shorter blocks and SRWs. This reduces the risk of wall failures caused by poor installation or inadequate design.
Superior Drainage Channels for Extra Protection
Safely and effectively remove rainwater and run-off from behind geogrid walls. This is made possible with the block’s hollow core offering horizontal and vertical internal drainage zones.
More Geogrid Tension & Resistance with Hollow Cores
Our system has a hollow core design filled with drainage gravel. This provides added connection between the geogrid, blocks, and internal drainage columns. The result is maximum drainage effectiveness for typical run-off and stormwater conditions.

How Do Geogrid Retaining Walls Work?
MagnumStone’s concrete blocks are used alongside geogrid layers. These layers are measured and placed between vertical rows of the blocks. The geogrid is installed securely between the retaining wall courses using precise techniques. The approved soil is then backfilled and compacted behind the wall for maximum tensile strength.
The blocks, soil, and geogrid complement each other to retain the earth’s structure. Certified labs carry out essential “Connection Capacity Testing” on geogrid-block connections. These tests are used for MagnumStone’s engineering software to help design secure retaining wall projects.
Common Applications for Geogrid Retaining Walls:
- Tall Walls – The sky is the limit, design and build taller wall heights can fit your project needs.
- Land Expansion & Development – Cut Walls & Fill Walls extend usable property space.
- Performance Under Pressure – Build strong, durable walls with heavy and active loads.
- Stormwater & Erosion Solutions – Contain, redirect, and manage any water applications.
- Bridge Abutments & Wing Walls – Ensure maximum strength, reinforcement and stability to support the weight of the bridge.
- Seawall Protection – Well-designed seawall protection prevents wall failures due to waves and tides.
When to Use Geogrid for Retaining Wall Designs
MagnumStone offers a free Retaining Wall Design & Analysis Software that examines essential, critical considerations. The software checks if geogrid is needed by analyzing heights, loads, soils, and seismic factors. If required, the software automatically determines the Geogrid length and strength. The retaining wall systems are engineered using various methodologies including NCMA, AASHTO, EUROCODE, and LRFD.
Retaining walls taller than 6 ft. (1.82 m.) typically need geogrid reinforcement. Geogrid walls cost less than cast-in-place concrete walls, which require extensive labor, massive footings, rebar and poured concrete.
Geogrid Retaining Wall Design Considerations:
- Integral Structures Within the Wall – Piping and Utilities
- Heavy Loads
- Slope Conditions Above and/or Below
- Soil Types
- Global Stability & Seismic
