If yes then you do not need to go anywhere as you are already in the right place. Cropper Bros Retaining Walls & Fences is a fully insured family business you can trust for such ventures with complete peace of mind. You must opt for a concrete retaining wall if your house is situated on a slope and the foundations are at risk of soil erosion. We build such walls in sloped yards as a prevention measure against erosion. A concrete retaining wall can hold back the soil, resisting erosion and thus making landscaping of the yard possible.
