ALVEOTER - Earth retention on slopes


During construction projects, the stability of slopes, natural or otherwise, and with varying gradients, must be guaranteed.

ALVEOTER® has a permeable three-dimensional structure that allows the soil to be confined and stabilized in the cells. When used on slopes, it effectively holds the soil in place to naturalize sterile surfaces with steep slopes.

The structure of ALVEOTER® and its composition in non-woven needlepunched geotextiles make it very light and easy to install (reduction of the accordion effect). It adapts easily to the irregularities of the support and to the geometry of the slope.

ALVEOTER® allows the use or reuse of a wide variety of materials, thus offering an efficient, economical and ecological solution.

This product is suitable for steep inclines (≥ 1H/1V) which are problematic for some geosynthetics. It can be implemented on slopes, SOMTUBE® FTF geocomposites and waterproofing layers (combined with the reinforcing geosynthetic).


  • Great long-term stability
  • Controls erosion on slopes
  • Installation on steep slopes (up to 1H/1V)
  • Flexibility and lightness
  • Adapts perfectly to the shape of the substrate
  • Simple transport
  • Relatively compact packaging

To stabilise slopes and drain water in a context of torrential rain, the solution implemented was a combination of the SOMTUBE® FTF geocomposite with an earth retention system, ALVEOTER®.
