The original 'hollow walls' were developed to provide as much protection from the elements as possible. Consisting of two separate leaves of brickwork with space between them, held in place with metal ‘ties’, they became known as cavity walls. Bricks become saturated, and are then damaged through freeze/thaw action, or where salts come to the surface and cause flaking and decay.Ĭavity walls can suffer from many of the same problems as solid brick walls. Crumbling of very soft or under-fired bricks over time.Structural issues, where movement can cause bricks to fracture.The later machine-made ones are more even in shape and colour.īrick walls may need repairs for a wide variety of reasons. Solid brick wallsīricks were originally made by hand using local clays and sands. This is especially important if your home is listed or in a conservation area (see Who Do I Contact?). If you want to make repairs to the walls of your home you may need to get permission and should seek advice. Most houses of traditional construction are built with brick or stone, or a combination of the two. Some of our earliest houses used timber framing, which was often a cheaper - and in some areas a more readily available - alternative to masonry.
