Extensions including garage conversions will often require extra 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 built to be in accordance with building regulations for habitable rooms. This damp proofing will need to be put into walls and floors. Additionally, the roofing of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will often be performed by employing 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 might have to be improved as part of the conversion in order to meet current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This can be carried out by either employing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already present in the garage. Damp proofing is a 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 incorporates appropriate damp proofing methods.

Signs of rising damp tend to be close to the ground, usually no higher than a metre. It usually works its way up walls in horizontal lines. Penetrating damp usually develops in patches and can often be much higher up. For more advice, speak to a damp proofing professional.
