Retaining walls may look like simple stacked stone, block, or timber. But in fact, they’re carefully engineered systems that wage an ongoing battle with gravity. They restrain tons of saturated soil that would otherwise slump and slide away from a foundation or damage the surrounding landscape.
Retaining walls are designed to compliment the landscape as well as providing structural strength and drainage solutions.
These handsome barriers also make inviting spots to sit, and can increase usable yard space by terracing sloped properties, something that is increasingly important as flat home sites become ever more scarce in many regions.
Along with sloped landscapes where water runoff causes hillside erosion, ideal locations for a retaining wall include spots downhill from soil fault lines and where the downhill side of a foundation is losing supporting soil or its uphill side is under pressure from sliding soil.
Various soil loads and pressures require different treatment depending on the position of the retaining wall, the load it is designed to take and the use of materials in its construction.
Treated Pine retaining walls are the cheaper alternative providing the soil that is to be retained, and hence the soil pressure, is minimal.
Brick retaining walls and stacked concrete or stone block are stronger than treated pine and offer a choice of attractive finishes.
A retaining wall that is required to hold significant soil pressure should be constructed from reinforced concrete or core filled concrete block. In some situations it is advisable for a structural engineer to custom design a solution.
All Day Fencing install concrete block retaining systems and core-filled structural retaining wall systems made from faced concrete blocks. There are six colours currently available, Oatmeal, Bondi Blend, Sunstone, Port Blend, Charcoal and Fossil as shown below.

Fence designs such as picket, paling, and timber slat can all be located on the top of retaining walls.
