Retaining Walls – Are they necessary?

Whilst recently undertaking a Structural Appraisal Report on a block on flats in the Croydon area, we noted that around the boundary of the flats was a retaining wall. Retaining walls are usually designed to prevent soil on an unnatural slope falling.

Whether or not to erect a retaining wall will usually depend on the soil type. Usually, retaining walls are used in conjunction with softer soil such as clay. Here, the property is on sandstone and a retaining wall is not necessarily required.
