What are Geogrid Reinforced Retaining Walls?
Geogrid reinforced retaining walls are load-bearing composite structures. These walls consist of compact soil backfill materials and geogrid layers. The geogrid layers provide reinforcement to the unreinforced soil.
Their integrated system includes big block retaining walls. These walls protect against soil erosion and support heavy or active loads above. They reinforce soil and further strengthen the wall.
These retaining walls expand land development projects. They also stabilize pressures caused by parking lots, civil structures, roadways, or bridges above the wall.
Geogrid retaining walls are cost-efficient for large walls. They use geogrid material, an engineered fabric made of polypropylene, to aid in soil reinforcement.
Geogrid reinforced retaining walls are a methodically engineered system comprised of:

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 crucial for engineering software programs to design retaining wall projects.

Designs
MagnumStone offers a free Retaining Wall Design & Analysis Software that examines essential factors. 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 like NCMA, AASHTO, EUROCODE, and LRFD.
Retaining walls taller than 6 ft. (1.82 m.) need geogrid reinforcement. Geogrid walls cost less than cast-in-place concrete walls, which require massive footings and rebar.
