Damp Proofing in Penryn

Extensions including garage conversions will typically require additional damp proofing to be installed through the conversion, as the existing garage normally has a single skin design for walls and floors, which was not built to conform to building regulations for habitable rooms. This damp proofing will have to be put into walls and floors. Furthermore, the roofing of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will in most cases be achieved by by using a damp proof membrane. This membrane is available in either solid or liquid form. The damp proof membrane will be placed down either on top of the existing concrete floor, underneath the new floor, or as part of both, depending on whether the floor will be a solid or a floating floor. In a few garages, the walls have been damp proofed, but this may need to be updated as part of the conversion in order to adhere to current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This is performed by either making use of damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to adhere to, therefore is it necessary to make sure that your garage conversion employs suitable damp proofing methods.

There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell.
