TENAX RIVEL System installation procedures

1. Precut the geogrids, shape the steel mesh formworks and prepare both the hooked bars. After the levelling and compaction of the foundation soil, place and line up the formworks connecting each other by mean of a steel or plastic wire.

2. Place the reinforcement geogrids in horizontal layers perpendicular to the face and along the internal face of the steel formworks, anchor the grids to the soil by means of "U" shaped staples and temporarily leave the last portion of the grids outside the formworks. The last portion of the grid shall correspond to the total wrapping length (about 1.5 m).

3. Place the biomats on the internal side of the geogrids at the face and place the hooked bars to fix the formworks.

4. Place the soil on the geogrids in approximately 0.30 m lift and compacted it until reaching a compaction not lower than 95% of Standard Proctor; for about 1.00 m close to the face the compaction shall be carried out by using light hand-held compactors, like vibrating plates, while the other part of the reinforced block may be compacted with heavy rollers.

5. Wrap the final portion of the grids, previously kept outside the formworks, toward the inside; slightly stretch it and anchor it to the soil by means of "U" shaped staples.

6. Repeat the phase 1-5 until completion of the work. Then hydroseed the face and, in case, place on the face a further biomat so as to hide the synthetics and metallic elements and to protect the hydroseeding.
