1. Prepare the site by removing all vegetative cover, debris and any unacceptable soils from the area where the geocell wall is to be placed. Replace any removed soils with acceptable materials and complete all earthwork in accordance with job specifications.

2. If geotextile is required by the job specifications, installation should be accomplished in accordance with the manufacturer’s recommendations.

3. Partially install stakes or J-hooks, leaving a protruding length of the cell depth plus approximately 2 in [50 mm], along the top edge of the area in which the geocell is to be installed. A string or chalk line may be used to align staking locations and borders.

4. Envirogrid sections should be stretched past the designed length ((typically, 20 ft [6.1m]), the allow to settle back to the designed length. Set the end cells of the geocell sections over the previously installed stakes and complete installation of the stakes or J-hooks flush with or slightly below cell walls.

5. Adjoining sections must be level and flush with each other. Overlap the sides of the geocell sections and butt the ends together. Secure adjoining sections to each other using a pneumatic stapler, hot rings or other means as required by the job specifications.

6. Install the balance of the stakes or J-hooks as required by the job specifications.

7. When the geocells have been properly laid into place, the system should be infilled using the materials specified in the job specifications.

8. To prevent possible damage to the system, limit the drop height of the infill to no more than 3 ft [1 m].

9. When using sand, granular or top soil fills, overfill the geocell sections by 1 - 2 in [25 - 50 mm] to allow for settling and compaction.

10. Sand and granular fills should then be blade compacted to the top of the cells. Top soil fills should be compacted with the loader or back hoe or with a tamper plate. Concrete fills should be manually raked and machine finished.
