Geocell Installation Guide For Slope Protection

Geocell Slope Protection System provides excellent protection for slopes against erosion through its designed expandable, strong, and cellular structure. It confines the desired infill and resists downward migration of material due to hydraulic flows.

The following are our installation recommendations for our cellular confinement system. A base installation crew is comprised of (5) laborers and (1) supervisor.

Step 1: Base Preparation

Prepare the site by removing all vegetative cover, debris, and any unacceptable soils from the area where the Geocell is to be placed. Replace any removed soils with acceptable materials and complete all earthwork, including going in trenches when required, in accordance with the job specifications.

Step 2: Geotextile Placement

If geotextile is required by the job specifications, installation should be accomplished in accordance with the manufacturer’s recommendations. Geotextile will not only protect the slope with filtration and drainage functions but also help the plants become strongly rooted.

For Projects over Geomembranes, make sure that the geomembrane or other geosynthetic material has been installed per the manufacturer’s instructions and that all earthwork has been prepared.

Step 3: Geocell Panel Prepare(Jointing)

Position the Geocell section along the slope direction. Panels will need to be either precut or joined depending on the length of the slope. Prepare precut or pre-connect panels at the top of the slope.

Join the panels, can use any kinds of our connectors. These keys are easy to install and made to last for a lifetime.

Step 4: Crest Anchoring

Anchor the upper edge of the Geocell to the top of the slope. Sometimes, the project may need anchor trench, which shall be excavated according to the project designs.

Step 5: Panel Expansion

Expand the Geocell panel down the slope to the panel’s specified length. Geocell panels should be stretched past the designed length and then allowed to settle back to the designed length.

Step 6: Toe Anchoring

Stretch the panels down the slope and stake every other cell at the bottom.

Step 7: Tendon(If required)

If the project design requires tendons, feed the tendons through the collapsed panel and attach one end to the dead man anchor in the anchor trench. Pull the tendons down the slope to the toe of the slope. With the tendons through the panel, tie each tendon to the cell wall every 3-6 cells, depending on the project requirement.

Step 8: Internal anchoring

On the internal of the section, install anchors in a staggered pattern with a spacing of 0.8-1.0m. For gentler slopes, the spacing can be increased to 1.5 m, and smaller diameter anchors or shorter length anchors can be used.

Step 9: Infill Placement

The fill material should be selected to meet the project and earth properties. Fill the cells with a front-end loader or dump truck (caution: Excessive drop height might hurt the cells. Drop height <0.6m is suggested).

Step 10: Overfill & Compaction

Infill material should be about 2-5cm higher than the cells to allow for settling and compaction. Finally, compact the Geocell system well in accordance with the design.
