Additional Support with a Retaining Wall
Constructing a retaining wall serves three main purposes – to support sloping earth, to drain any water and to reduce hydrostatic pressure. The most common type of retaining wall is the cantilever wall. A cantilever retaining wall is constructed with a free-standing barrier which does not have any lateral support at the top. The retaining walls tend to cantilevered from a footing which reaches up past the grade on one side. On the other side, it holds back a higher level grade.
It is important to hire a piling contractor who has specialist knowledge of retaining walls. Planning is key to an effective, stable retaining wall as they need to be constructed so as to resist the pressure of both soil and water.
Another common retaining wall design is the anchored retaining wall. Anchors are placed deep into the ground to support the retaining wall from behind. The method of soil nailing is then often used to reinforce the retaining wall. Soil nailing involved drilling into the ground and installing steel tendons. These are then grouted to create a composite mass which is similar to a gravity wall.
