Damp Proofing in Truro

Extensions including garage conversions will often require additional damp proofing to be added during the conversion, as the existing garage will often have a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing will need to be put into walls and floors. Additionally, the roof of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will usually be performed by by using 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, below 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 been damp proofed, but this might have to be updated as part of the conversion to be able to comply with current building regulations. The walls will need to be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This is carried out by either using 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 important to ensure that your garage conversion incorporates appropriate damp proofing methods.
