Damp Proofing in Diss

Extensions including garage conversions will often require extra damp proofing to be installed through the conversion, as the pre-existing garage routinely has a single skin design for walls and floors, which was not designed to conform to building regulations for habitable rooms. This damp proofing should be added to walls and floors. Furthermore, the roof of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will usually be achieved by by using a damp proof membrane. This membrane will come in either solid or liquid form. The damp proof membrane will be placed 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 a few garages, the walls have already been damp proofed, but this might need to be updated as part of the conversion in order to comply with 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 accomplished by either implementing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is an integral part of the building regulations that the garage conversion should comply with, therefore is it important to ensure that your garage conversion incorporates suitable damp proofing methods.
