Cement in old buildings 4Traditional constructed walls, or solid wall construction, typically used either a natural lime mortar and/or a clayey earth as the common binder. These mortars allow a degree of natural movement. When inflexible, cementitious materials are introduced to old walls, the underlying, historic building fabrics will continue to flex and move resulting in surface failings.

 Cement in old buildings 5Equally, an old solid wall constructed of brick, stone or cob needs to be able to breathe, and if cementitious materials are used, breathability cannot be achieved. In addition, excessive moisture content within the substrate will be trapped and can cause damp problems in old buildings in Cornwall.
