- Big Rock Concrete
There are two popular construction methods for concrete retaining walls depending on the height of the wall. The first one is designed for walls under 2’ in height. This type of wall is typically anchored in place using pilings. The second method involves using a poured concrete footing to support walls over 2’ in height. The footing is normally offset so that the wall can withstand the substantial force of the soil that the wall is built to retain. In extreme circumstances other methods could be combined to deal with different situations.
Although permits are not always required for retaining walls under 4’ in height, it is always advised that the homeowners check with their local development department to ensure that their construction plan complies with the local bylaws for their area.
