Retaining Wall Reinforcement Grid

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. 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. When grid is needed depends on the wall building material but also the soils being retained.

Retaining wall reinforcement grid.

Retaining wall with reinforced soil cross section. 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. It is available in 3 ft. The geogrid acts as a tie back to resist the outward movement of the retained soil.

Long 0 9 m and 1 2 m by 15 m and is best used for residential retaining walls under 6 ft. The patented keystone compac a leading commercial retaining wall product features an open core design and a pin connection system. Ab reinforcement grid is a high strength polyester mesh geogrid that is coated with a black protective film. 1 8 m tall as outlined in the table above.

Rolls and is 50 ft. When is geogrid needed in a retaining wall. It is used to give added strength to the retaining wall by reinforcing the soil behind it. Ab reinforcement grid is biaxial which means it has the same strength in both directions and can be simply rolled out along the wall.

As a wall gets taller it needs longer geogrid lengths to increase the size of the geogrid reinforced soil mass. 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. 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 geogrid holds the soil in place to allow the retaining wall to function.

The first cylinder is just compacted material. Lock retaining walls in place with ab reinforcement grid. Geogrid is an open mesh grid structure that is placed in horizontal layers to reinforce retaining walls. 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.

Properly designed versa lok walls with versa grid soil reinforcement can be constructed to heights of 50 feet or more. 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. Use the soil reinforcement chart to determine the size of ab grid you will need and how many layers your retaining wall requires. The sand castle test takes two cylinders of soil and applies vertical force to see how the soil performs.
