Extensions such as garage conversions will usually require additional damp proofing to be added through the conversion, as the existing garage will often have 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 added to walls and floors. Additionally, 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 performed by using a damp proof membrane. This membrane will 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 if the floor will be a solid or a floating floor. In a few garages, the walls have already been damp proofed, but this might have to be improved as part of the conversion in order to comply with 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 is accomplished by either making use of damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present in the garage. Damp proofing is a part of the building regulations that the garage conversion should comply with, therefore is it important to ensure that your garage conversion makes use of appropriate damp proofing methods.
