Stabilizer Grid Installation

Stabilizer Grid can be installed quickly and easily with a small crew of semi-skilled laborers without any specialized equipment. Grid panels are delivered to the job site in a collapsed form, when expanded they cover an area measuring 13' x 13'

Excavate and shape the sub-grade soil to the appropriate depth based on the cell depth of the stabilizer grid and the finished product being installed.
Note: If the infill material is different from the sub-base material, a geotextile should be used as a separator. A woven or nonwoven fabric is selected depending on whether strength or permeability is important. Simply unroll the geotextile directly on the sub-grade, overlapping adjacent panels by 18" (minimum).
Place stakes in the four corners where the first stabilizer grid is to be placed.
Stretch the stabilizer grid section beyond its intended length and allow it to relax. Place the section over the embedded stakes. Additional stakes may be required along the perimeter in order to get full expansion of each cell. Adjacent sections are installed in a similar fashion and butted or stapled together to achieve continuous coverage.
Fill the first row of cells using a loader, dump truck, wheelbarrow and push the fill into the cells using a shovel or a smooth blade of a loader bucket.
Note: Be careful when using a tooth rake or tooth bucket not to snag the cell material. This can cause the grid to pull out of place.
Create a ramp of fill material in order to allow equipment to climb onto the stabilizer grid. Continue until all cells are filled. Overfill top of cell by approximately 1".
Note: Never allow equipment to drive over unfilled cells. Always overfill cells to allow for consolidation and compaction.
It is now necessary to compact the stabilizer grid system. This process can be done using multiple passes with a tracked equipment, vibratory plate compactor or roller. Water can be used in order to achieve the specified level of compaction.
Once the cells are filled and the system is compacted, the stabilizer grid base system is ready to withstand heavy loads.
