Historic building fabrics do not perform in the same way as modern building materials. Repairs to historic buildings using impermeable applications can lead to deterioration of historic substrates.

Cement in Old Buildings Cornwall

Traditional 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.

Inappropriate Cement Pointing

Equally, 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.
