Retaining walls are a complex hardscape element that require the right design to be built properly. They are designed to prevent upper level soil from collapsing and must be built with the correct footing and foundation to avoid failure. Unfortunately, retaining walls are often built incorrectly and this can have disastrous results. The worst outcome is that a wall can fall, which could damage your landscaping and even cause an injury on your property. The best way to avoid this is to hire a professional landscaper who specialises in building retaining walls.

To build a retaining wall, you will first need to dig a trench around the area of your wall. This will need to be at least eight inches deep, but no more than ten feet wide. Once you have dug your trench, use a shovel to cut away any material that isn’t part of the retaining wall. You should then tamp down the soil and cover it with a layer of gravel that is four inches thick. This will help to keep the backfill from becoming too loose, which can lead to a leaning retaining wall.

This can save you money up front, but it will cost you a lot more in the long run if your wall fails and falls down.
