ALVEOTER - Soil stabilization on slopes


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.


  • Erosion control on slopes
  • Installation on steep slopes (up to 1H/1V)
  • High stability over time
  • Flexibility and lightness
  • Perfect adaptation to the shape of the support
  • Easy to transport
  • Low volume packaging

To enable load bearing and earth retention to a depth of 15 cm for long-term revegetation, the ALVEOTER® solution was implemented on the slopes of an infiltration pond, with 45° gradients.
