Retaining walls enhance all kinds of gardens, both flat and sloping ones. Concrete blocks will make the construction of these walls easy. You could opt for hollow blocks filled with mortar and reinforced with steel rods for extra strength. A more straightforward way to set up the wall is by using interlocking concrete blocks that click together without the need for mortar. Here are several ideas on how to use concrete block walls in your yard.
Create a Feature
Level gardens can sometimes be bland and lack focal points. To add interest, you could build a circular retaining wall around an elevated garden bed in the middle of a flat garden.
You might assume that concrete blocks only have a smooth, grey finish. But they offer many more options than this. The concrete is set in moulds during manufacturing to give it shape and texture. And it's coloured with pigments and dyes, often to look like natural substances. Thus, you'll have plenty of choices. Create a beautiful centrepiece with golden blocks that mimic sandstone or opt for charcoal-hued blocks.
You could build a rustic, circular retaining wall in blocks that emulates cobblestone surrounded by the lawn. If you want to create a more elaborate design, you could create loose gravel or paver paths leading up to the focal point.
Hide the Backyard Fence
Does your backyard consist of grass that reaches the fenceline? Or is the fence lined with non-descript garden beds? If so, you could build raised terraces along the fence line using concrete block walls. You could construct one tier or a multi-tiered effect. Two levels will showcase the shrubs and flowers you plant, as they'll be higher and closer to your eye line. These perimeter garden beds will also soften the fence line so that it's not too abrupt. Plus, they'll help keep pets off the garden to prevent them from digging it up.
Concrete block retaining walls are also ideal for creating multiple levels in a sloping garden. You could build steps leading to an outdoor patio and add a table and chairs to relax on while enjoying the view. For such a complex structure, you'll need a structural engineer's advice on how the wall is built to ensure it's strong enough. Local council regulations will specify the rules.
Levelling out a property in this way also increases its health as the rain won't run down the hillside and tear off the nutrient-rich topsoil. Instead, the water will have a chance to soak into the earth and provide nourishment. Plus, you'll be able to access all parts of the garden more easily. The multiple levels will give the garden an appealing sculptured look.
