Extensions including garage conversions will usually require extra damp proofing to be added as part of conversion, as the existing garage normally has a single skin design for walls and floors, which was not built to be in accordance with building regulations for habitable rooms. This damp proofing will need to be put into walls and floors. Moreover, the roofing of the garage conversion will require water proofing. The damp proofing of 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 put down either on top of the 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 some garages, the walls have been damp proofed, but this might need to be updated as part of the conversion to be able to meet current building regulations. The walls will need to be damp proofed to be able to safeguard the brickwork from rotting slowly as moisture sets in. This can be performed by either making use of damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present in the garage. Damp proofing is an important part of the building regulations that the garage conversion will need to comply with, therefore is it vital to make sure that your garage conversion makes use of appropriate damp proofing methods.
