Extensions including garage conversions will often require extra damp proofing to be installed during the conversion, as the existing garage normally has a single skin design for walls and floors, which was not designed to conform to building regulations for habitable rooms. This damp proofing will have to be added to walls and floors. In addition, the roofing of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will most likely be performed 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 pre-existing concrete floor, below 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 will need to be damp proofed to be able to safeguard the brickwork from rotting gradually as moisture sets in. This can be carried out by either applying damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present in the garage. Damp proofing is an important part of the building regulations that the garage conversion will need to adhere to, therefore is it vital to ensure that your garage conversion incorporates appropriate damp proofing methods.
