Slope Protection Geocell

The Geocell slope and shoreline protection system confines. reinforces and restrains the upper soil layer and infill controlling down-slope movement and slippage due to hydrodynamic and gravitational forces.

• Provides effective slope protection and structural confinement of topsoil/vegetation and granular materials suchas send, gravel and larger rock or stone.
• Becomes a flexible concrete mat with built-in expansion joints when cells are infilled with concrete.
• Creates additional stability by integrating tendons on steeper slopes and shoreline embankments or when a geomembrane or hard soil/rock surface prevents anchoring with stakes.
• Allows embankments to be steeper than when unconfined, reducing use of valuable land space.

Subgrade Preparation

• Excavate and shape foundation soils.
• Insatll a geotextile underlayer on prepared surfaces.
• If required, install geogrid underlayer on prepared Surfaces.

Geocell Panel placement and tendon fixing

• First calculate the length of the slope in order to determine the number of panels required and the length of your tendons.
• Allow approx. 200 mm for each securing anchor to be tied off plus an additional 1 m per tendon run for anchor placement. The number of securing anchors and tendons used will depend on the gradient of the slope. (i.e the steeper the slope the more anchors and tendons required.)
• Position collapsed geocell panels at crest of slope. Secure tendons at the crest of the slope with galvanized anchors.
• Feed the tendon through the first collapsed panel. Secure subsequent panel / s with connecting studs and continue to feed tendon through each individual collapsed panel.
• Once the tendon has been fed through all panels, fully extend tendon down the slopw
• Drive a rebar J- Pin trough every perimeter cell along the crest of the slope to secure the top edge of the geocell panels in place.
  Begin to expand the panels / s down the slope, securing the panels as you go with J-pins (according to suggested laying pattern) in their fully expanded postion.
• Once the entire matrix has been positioned, return to tendons working from the crest down, drive in anchors tight against the cell walls in line with tendon.
• Take the slack from the tendon and wrap it aroung the central column 3 or 4 times before repeating the process on the next anchor.
• Tie off the tendon securely on the last anchor at the bottom of the slop, drive a rebar-J-Pin Through every perimeter cell along the final row.

Infill Material:

• Infill expanded panels with chosen material working from the bottom of the slope up towards. the crest (for less exposed slopes seeded top-soil is suggested, adding small shrubs will give improved protection).
• Limit Drop height to a maximum of 1 m to avoid damage or displacement of the cell walls.
• Compact infill material per engineer's specification.

Typical applications

• Cut or fill embankment slopes
• Shoreline revertments
• Abutment protection
• Stormwater / Waste water lagoons
• Containment dikes and levees
• geomembrane protection
• Landfill linings and covers
• Dam faces and spilways
