Extensions including garage conversions will usually require additional damp proofing to be installed through the conversion, as the pre-existing garage routinely has a single skin design for walls and floors, which was not manufactured to be in accordance with building regulations for habitable rooms. This damp proofing should be added to walls and floors. In addition, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will most likely be performed by employing 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 if the floor will be a solid or a floating floor. In some garages, the walls have already been damp proofed, but this might have to be updated as part of the conversion to be able to adhere to current building regulations. The walls should be damp proofed to be able to safeguard the brickwork from rotting slowly as moisture sets in. This can be accomplished 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 an important part of the building regulations that the garage conversion should adhere to, and so is it vital to ensure that your garage conversion employs appropriate damp proofing methods.
