@markmarshalllsh: Retaining walls are useful structures that form a transition between areas of different elevation. Retaining walls allow steep, unusable slopes to be avoided. A retaining wall will make use of the vertical forces from the wall itself and any soil above the wall’s footing to resist the lateral forces from the soil being retained. This balance can be upset when additional lateral forces act on the wall. #landscaping #retainingwall #sleepers #garden #woodworking
