In many cases, it also involves aligning the blocks and stacking them on top of each other until the desired height and length are reached. However, there are certain factors that can add complexity to this process. Here are some considerations to bear in mind when undertaking the construction of a sandstone retaining wall.
Choosing the Right Blocks
Carefully consider the grade of block you are ordering. As the distinct characteristics of each grade can impact the construction requirements for your wall. For more information about each grade, please refer to our sandstone blocks pages.
Block Weights
Make sure that the selected block size is sufficiently heavy to withstand the pressure exerted from behind the retaining wall.
Approximate block weights
400 x 400 x 1000-1100mm approx 400kgs each
500 x 500 x 1000-1100mm approx 600kgs each
600 x 600 x 1000-1100mm approx 900kgs each
Footings
It is crucial to establish a sturdy foundation to prevent any potential shifting that could compromise the structural integrity of the wall. Therefore, the specifics of each case can vary depending on the site. It is important to consider the composition of the natural ground where the blocks will be also be laid. For basic soil/clay foundations. Especially when there is ground water present. We recommend using a compacted road base at minimum to enhance the stability of the footing.
Drainage
Make certain that your wall is equipped with adequate drainage to prevent water accumulation, which can lead to increased earth weight behind the wall, elevating pressure and potentially compromising structural integrity.
