EARTH RETAINING STRUCTURE

Retaining walls are structure used to hold soil, rock or other materials in a vertical situation.

Therefore they provide a lateral support to vertical slopes of soil that would otherwise collapse into a further natural shape.

 Most frequent materials used for retaining walls are:
- Wood sheets;

 - Reinforced concrete sheets;

 - Wire-mesh boxes (gabions);

 - Precast concrete elements (crib walls and block walls);

- Narrowly spaced in-situ soil-cement piles;

 - Steel and plastic interlocking sheets;

- Anchors into the soil or rock mass (soil nailing).
