Build a stronger retaining wall with these geogrids!SRW makes its geogrids with a high-end, multi-filament polyester yarn. They then weave this high-tenacity yarn into a stable network, place it under tension, and then coat it with PVC. Use the universal series geogrids for retaining walls of up to 6 feet in height. Choose the 3-series for retaining walls of up to 10 feet in height.
