Types of Retaining Wall

Anchored
Anchored

Anchored retaining wall Anchored wall-is a wall that is usually pinned both top and bottom using cables, or other stays, which are anchored in the rock or soil behind it.Anchors are driven into the material and then expanded at the end of the cable, either by mechanical means or by injecting pressurised concrete into the hole.

Bored Pile
Bored Pile

Secant Pile Wall – Hard/Soft or Hard/Firm Where short term water retention is required this system offers the most cost-effective and rapid solution. The wall consists of interlocking bored piles. Primary piles are constructed first using a 'soft' cement-bentonite mix (commonly 1N/ mm2) or 'firm' concrete (commonly 10N/mm2).

Cantilevered
Cantilevered

Cantilever Retaining Walls. Cantilever retaining walls are constructed of reinforced concrete. They consist of a relatively thin stem and a base slab. The base is also divided into two parts, the heel and toe. The heel is the part of the base under the backfill. The toe is the other part of the base.

Gravity
Gravity

Gravity Retaining Walls. It is that type of retaining wall that relies on their huge weight to retain the material behind it and achieve stability against failures. Gravity Retaining Wall can be constructed from concrete, stone or even brick masonry. Gravity retaining walls are much thicker in section.

Mechanical Stabilization

Precast concrete retaining wall A diagram of a mechanically stabilized earth wall as it would be modeled in a finite element analysis. Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing.

Sheet Piling
Sheet Piling

Sheet pile walls are constructed by driving prefabricated sections into the ground. Soil conditions may allow for the sections to be vibrated into ground instead of it being hammer driven. The full sheet pile wall is formed by connecting the joints of adjacent sheet pile sections in sequential installation. Sheet pile walls provide structural resistance by utilizing the full section.

Soil Nailing
Soil Nailing

Soil nail components may also be used to stabilize retaining walls or existing fill slopes (embankments and levees); this is normally undertaken as a remedial measure. Since its first application using modern techniques in Versailles in 1972, soil nailing is now a well-established technique around the world. One of the first national guideline publications for soil nailing was produced in Japan in 1987.

Soil-Strengthened
Soil-Strengthened

Retaining walls are relatively rigid walls used for supporting the soil mass laterally so that the soil can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope).
