Geocell Installation Guide For Soil Stabilization
The followings are our installation recommendations for our cellular confinement system. A base installation crew is comprised of (5) laborers and (1) supervisor.
Step 1: Subgrade Preparation
Excavate and prepare the subgrade according to the project engineer’s specifications. Ensure the correct depth and slope are achieved. Compact the subgrade in lifts as required.
Step 2: Geotextile Placement
A non-woven geotextile is placed directly onto the compacted subgrade to act as a separation layer, preventing mixing of subgrade soil with the infill material.
Biaxial geogrids may also be installed at this stage if specified.
Step 3: Geocell Panel Deployment
Determine where the first section of Geocell is to be placed and choose the direction of the expansion of the panels based on the geometry of the area.
Install a series of temporary stakes or pins over which selected edge cells would be hooked. Typical stakes are straight rebar, 3 times the depth of the cell. Once the Geocells are filled, the stakes can be removed and re-used.
Step 4: Panel Expansion
Fully stretch the panels to their standard expanded length, ensuring the honeycomb cells are open and uniform, and allow it to relax.
Step 5: Panel Joining & Securing
Join the panels, can choose any kinds of our connectors. These keys are easy to install and made to last for a lifetime. Each cell along the width and the length must be attached at the joints.
When first pulled open, the cells will have the tendency to open in an hourglass shape. When proper length is reached, pull the panel edges to ensure rectangular expansion. Then, stake the panels at each cell along the width at either end, and along the cell every other cell.
Step 6: Infill Placement
Fill the cells with the choice of infill material. An excavator can be used to push the fill material onto empty cells. When dumping fill material, keep the bucket as close to the empty cells as possible and limit drop height to no more than 0.6m above the cells.
Continue until all cells are filled. Never allow any equipment to drive over an unfilled area. Once filled, the stakes can be removed.
Step 7: Overfill & Compaction
Overfill the top of the Geocell by 50–75 mm for consolidation. Compact the infill using a 9-ton (or heavier) vibratory roller until the design compaction is achieved.
Once the cells are filled and the aggregate compacted, the Geocell-constructed base is ready to withstand heavy traffic loads.
