Geocell Installation Guide For Channel Protection

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 cross-section of the channel direction. Precut or pre-connect panels at the top of the slope to cover the slope if the slope is the only section being lined, or calculate length based on the full cross-section of the channel.

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. Anchoring will be based on channel geometry, area lined (full channel or only slopes), and flow velocities. Sometimes, the project may need anchor trench, which shall be excavated according to the project designs.

Step 5: Panel Expansion

Stretch the panels down the slope and stake at the bottom of the slope every other cell, or if the full channel is lined, also across the bottom and up the opposite slope area.

Step 6: Toe Anchoring

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

Step 7: Tendon(If required)

If a tendon system is being used, feed the tendon through the collapsed Geocell panel and attach one end to the dead man anchor in the anchor trench. Have enough tendon to reach the opposite side anchor. Enough tendon will be needed to tie to the cell walls. A single tendon length should be used along the full cross-section of the channel.

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 1.5m, 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.
