Extensions including garage conversions will often require extra damp proofing to be added through the conversion, as the pre-existing garage routinely has a single skin design for walls and floors, which was not built to comply with building regulations for habitable rooms. This damp proofing will need to be added to walls and floors. Additionally, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will in most cases be achieved by utilising a damp proof membrane. This membrane can come in either solid or liquid form. The damp proof membrane will be put 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 some garages, the walls will have already been damp proofed, but this may 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 protect the brickwork from rotting gradually as moisture sets in. This is done by either utilising 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 necessary to make sure that your garage conversion employs appropriate damp proofing methods.
