Retaining Wall Reinforcement Grid

The patented keystone compac a leading commercial retaining wall product features an open core design and a pin connection system.

Retaining wall reinforcement grid.

Retaining wall with reinforced soil cross section. Also taller walls need more layers of geogrid and stronger geogrids to internally hold the reinforced soil mass together and to properly connect to the versa lok units. 1 8 m tall as outlined in the table above. The first cylinder is just compacted material.

If you consider a simple gravity retaining wall the forces from the soil being retained must be retained by the mass of the wall blocks. Long 0 9 m and 1 2 m by 15 m and is best used for residential retaining walls under 6 ft. Geogrid is an open mesh grid structure that is placed in horizontal layers to reinforce retaining walls. Ab reinforcement grid is biaxial which means it has the same strength in both directions and can be simply rolled out along the wall.

Adding geogrid to a retaining wall recruits the retained soils as helpers in retention essentially making the retaining wall far more massive than the weight of the block or stone alone. When is geogrid needed in a retaining wall. Both wall systems are comprised of dry cast concrete keystone compac modular units and ntpep evaluated tencate miragrid xt polyester geogrid soil reinforcement by tencate geosynthetics. It is used to give added strength to the retaining wall by reinforcing the soil behind it.

As a wall gets taller it needs longer geogrid lengths to increase the size of the geogrid reinforced soil mass. Rolls and is 50 ft. Ab reinforcement grid is a high strength polyester mesh geogrid that is coated with a black protective film. It is manufactured using select grades of high density polyethylene hdpe resins that resist elongation or creep when subjected to high loads for long periods of time.

The sand castle test takes two cylinders of soil and applies vertical force to see how the soil performs. When you use geogrid with a retaining wall the mass of the blocks and the additional mass of the reinforced soil helps to withstand the pressures behind the wall. The geogrid acts as a tie back to resist the outward movement of the retained soil. Use the soil reinforcement chart to determine the size of ab grid you will need and how many layers your retaining wall requires.

The geogrid holds the soil in place to allow the retaining wall to function. When grid is needed depends on the wall building material but also the soils being retained. Earthlock retaining wall geogrid with tensar ux technology is designed to easily and efficiently reinforce soil slopes rss and segmental block retaining walls srws. Engineered for durability and long life versa grid geogrid soil reinforcement is a high performance soil reinforcement composed of high molecular weight woven polyester yarns with a polymeric coating.
