Embankment wall for building - has dressed top to take roof timbers and concrete footing to reduce subsidence

摘要

The wall is of low cost, inert and stable earth, gravel or small stones, or is artificial such as foundary slag, while the base of the wall is wider than the top and the height is sufficient to support the roof timbering. The wall has openings for doors and windows, with internal drains, and if the material is susceptible to substantial later settlement, a masonry capping or concrete footing is placed on top of the wall to take the roof of the building.
