Extensions such as garage conversions will typically require supplementary damp proofing to be added as part of conversion, as the pre-existing garage will often have 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. Furthermore, the roof of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will most likely be performed by utilising a damp proof membrane. This membrane can come 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 some garages, the walls will have already been damp proofed, but this may 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 in order to safeguard the brickwork from rotting gradually as moisture sets in. This can be carried out by either utilising 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, and so is it vital to make sure that your garage conversion employs appropriate damp proofing methods.
