Retaining structure can be the main measure of stabilization of landslides, alone or in combination with drainage, relief of the upper slide mass of the landslide, geotechnical anchors etc. It directly or indirectly increases the resistance to slipping at the footing bottom, either by increasing the weight or by introducing new forces.
Prefabricated RC walls (crib walls) can have more constructive shapes. The basic type consists of two types of prefabricated RC elements. These are longitudinal and connecting (or transverse) elements that form a sort of a cage and thus form a space for filling with coarse material. The fill can be made of sand, gravel, or crushed stone, without the greater proportion of fine particles, in order to provide water permeability.
