Restoration and reinforcement of a scarp, comprising of the following: surface of scarp to be restored is prepared; the prepared surface is filled with soil; a retaining wall is erected, which is covered with a protective layer, a drain layer is installed in the scarp, characterised in that - below the foothill of the scarp a pit for the retaining wall is created, filled with a layer of mineral soil with coarse-grain granulometric composition, which is compacted to the subsoil as a foundation for the retaining wall, with a minimum downward gradient of two per cent away from the scarp; - a horizontal protective filter formed of compacted draining mineral soil and surrounded by pre-tensioned draining geotextile is installed at the foothill of the scarp, wherein the horizontal protective filter comprises soil sections with different seepage coefficients; - the soil sections of different seepage coefficients contained in the horizontal protective filter are separated from one another by means of a pre-tensioned geotextile; - a geogrid of inert material is installed on the surface of the regressed scarp and is anchored to the firm soil layer of the scarp by means of tensile ropes; - a draining geotextile is installed under the geogrid; - a rigid support is created on top of the horizontal protective filter, under which batter piles that act on pull and pressure are sunk, supporting the piles on a firm soil layer in the subsoil; - the batter piles of the rigid support are sunk or driven, intersecting at the horizontal line of the vertical plane that runs through the centre of gravity of the rigid support, while the horizontal line is parallel to the front edge of the scarp; - a retaining wall is created, which contains layers filled with compacted mineral soil, which are surrounded by pre-tensioned geotextile; - the soil layers of the retaining wall are formed of soil layer sections with different granulometric composition, while the soil layer sections installed on the external side and internal side of the retaining wall are formed of draining mineral soil, wherein the soil layer sections constitute vertical protective filters of the scarp, and the middle sections of the retaining wall are formed of fine-grain soil; - the retaining wall is covered with erosion control mats, which are secured to the geotextile of the soil layers of the retaining wall by means of clamps of inert material; - the foot of the retaining wall of the scarp is supported by means of a counterweight; - the foundation of a building located in a slip-prone area of the scarp is supported by means of batter piles to a firm soil layer located underneath. - below the foothill of the scarp a pit for the retaining wall is created, filled with a layer of mineral soil with coarse-grain granulometric composition, which is compacted to the subsoil as a foundation for the retaining wall, with a minimum downward gradient of two per cent away from the scarp;

- the foundation of a building located in a slip-prone area of the scarp is supported by means of batter piles to a firm soil layer located underneath.
