Damp Proofing in High Wycombe

Extensions including garage conversions will typically require extra damp proofing to be installed during the conversion, as the existing garage typically has a single skin design for walls and floors, which was not manufactured to comply with building regulations for habitable rooms. This damp proofing will have to 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 by using a damp proof membrane. This membrane is available in either solid or liquid form. The damp proof membrane will be put down either on top of the pre-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 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 should be damp proofed in order to safeguard the brickwork from rotting gradually as moisture sets in. This is accomplished by either implementing 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 suitable damp proofing methods.
