A retaining wall can make your property more usable if it's on a hill. These walls can be used to create level areas that are easier to access, on which you could establish extra garden beds or a patio. Steps will let you get to all areas safely.

If you're looking for a material option, concrete block retaining walls are an excellent choice. You could opt for interlocking blocks that don't need mortar. Alternatively, contractors can use Besser blocks with hollow sections. They can fit steel rods through the hollows and fill the bricks with mortar. This more complicated structure is ideal for large walls that need bolstering. Besides choosing the material, you'll have other aspects to consider when planning a retaining wall. Read on for more information about what to consider when building a block retaining wall.

Structural Engineer

A retaining wall sometimes needs input from a structural engineer who can assess whether it's strong enough and structurally sound. Retaining walls hold back the weight of the soil on one side, so many calculations go into working out their capacity.

Often, walls of a certain height will automatically need the input of a structural engineer and council approval, adding to the cost. The wall's location is also relevant. Some walls require approval if they're close to the property boundary. Contact your local council to find out the regulations for your region.


Another aspect to consider when building a retaining wall is access to your property. If contractors can't easily move their equipment and materials into the yard, costs can escalate as the job will be trickier and take longer. Additionally, obstacles that may be in the way of the wall need to be removed, such as sheds or trees. These tasks will add to the cost of building the wall.


Retaining walls may be practical structures, but they're also decorative. One of the benefits of using concrete is having endless looks at your disposal. Interlocking blocks come in various colours and textures, some mimicking natural stone. Capping blocks create a stylish finish to the wall top.

Concrete walls can also be rendered in any colour to blend with the landscape. You could colour them the same hue as your home's roof or external walls. You should also factor in the paving and natural landscape when selecting the design of the wall to blend it with the environment. For example, you can build straight or curved walls, whichever is more appropriate to the setting.
