Retaining Walls 

A retaining wall is used to block soil and hold it from getting at the area behind the wall. It can be constructed using any of several materials, such as concrete, timber, or boulders. A retaining wall may be a long-term structure, or even something temporary, depending on its purpose. In most cases, they connect two levels of elevation and help protect the landscaping on the lower level. Landscaping Ninjas is the retaining wall experts, and will make sure that the construction is not only durable and long-lasting but that it also adheres to all safety standards and by-laws. 

Gravity Retaining Wall

A gravity retaining wall is installed using its own weight for support. They tend to be shorter in height than other types of retaining walls and are usually installed using an interlocking technique that creates a setback for more support. A setback helps to protect the wall against the pressure from the soil that is pushing on it from behind. A gravity retaining wall is most often made of reinforced concrete. 

Piling Retaining Wall

Piled retaining walls are created by screwing large piles into the ground at lower depths to provide support. They are then lined to prevent soil or other materials from sliding back through. This type of wall is often used during excavations so that the newly released soil will not tumble back into the hold. They are often temporary, but can also be permanent, depending on the location and if there is a continuing need outside of excavation. Piles can be steel, concrete, or wood, and are very secure, owing to how deep they are placed into the soil. 

Cantilever Retaining Walls

Cantilever retaining walls tend to be made of reinforced concrete. They are more heavy-duty than many other walls and are for large projects. They can be up to 25 feet and are constructed with a base and stem design. The base acts somewhere like a door stopper that is placed under the backfill. It provides the weight to keep the wall and the soil in place. Landscaping Ninjas will carefully calculate the size of the cantilever needed to properly protect against water and soil so that the wall does not fail. 

Anchored Retaining Walls

As the name would suggest, these retaining walls are held in place by cables or other supports that are anchored to a sturdy structure. In most cases, this structure is rock or even deep into tightly packed soil. The anchor is held in place using pressurized concrete that is injected into the anchor hole and then expands to secure it. This type of wall is known to be able to withstand great amounts of pressure. It is a perfect option when the wall needs to be thin to fit into a certain space, and would otherwise be too flimsy to hold up. The anchoring provides tremendous support, even with heavy loads. 

What a retaining wall is used for your landscaping or excavation project will depend on several factors, such as the nature of the backfill, the angle of the soil levels, and the type of soil or other material that it will be holding back.
