Types of Concrete Retaining Walls

Drilling deep in the ground to set a good foundation

Many people in the construction industry use retaining walls. They use retaining walls in the construction of masonry dams, hill roads, bridge wing walls and more.

The construction material for your retaining wall will depend on the type of material, the height of the wall, and the condition of the construction site. Thus, before making any decision on the kind of raining wall to construct, consult your contractor in Bay of Plenty. Here are options that you may discuss.

Gravity Retaining Walls

These massive retaining walls employ create proper stability. They are made of plain concrete or masonry. However, plain concrete should only be used for walls whose height is below three metres. They are often used during the construction of simple dykes or dams.

Cantilever Retaining Walls

These are constructed using reinforced concrete. They consist of a thin slab and a base stem, with the base divided into two parts known as the toe and the heel. While these walls use much less concrete than other retaining walls, they require professional designs to be functional. They can be constructed on the site or precast in a factory.

Anchored Retaining Walls

Also known as tiebacks, these retaining walls are suitable for projects that require high retaining walls. Wires or cable rods are deeply set into the earth, and their remaining edges are filled with concrete to create an anchor. They are best used in construction projects where there is a space limitation or projects that require thin retaining walls. They are suitable for most highway construction projects.

If you want to ensure the stability of the retaining wall, you must consider various factors. For example, the wall must be proportional to prevent overturning or sliding, and the structure should resist any pressure.
