ABSTRACT:
The invention relates to a device, especially for stabilizing soil material and other moldable compositions such as uncured concrete or the like, comprising a substantially elongated web sheet mounted on a support which forms a plurality of cells or pockets which can be manufactured from inexpensive raw material, which possibly can easily decompose, and requires a minimum transport volume. The device provides favorable anchoring in the ground which is to be soil stabilized and forms pockets or cells having walls extending vertically independent of the slope angle of the ground for stabilizing the soil even during heavy rain. The web is constituted by an initially relatively thin, substantially flat web sheet, preferably of flexible plastic, which in a first direction is provided with rows of consecutively arranged slits which are so staggered relative to each other that the web by the stretching thereof in a second direction forms oppositely undulating strips which upon mounting of the web on a more or less inclined hill, define side by side arranged cells or pockets which can be filled with soil or other material being stabilized by the device. Due to the lower edges of the undulating strips, the device in stretched condition may easily be pressed down into the ground for anchoring in the ground and the various degrees of stretching can be harmonized to the various angles of inclination of the ground.
