Damp Proofing in Darwen

Extensions such as garage conversions will often require extra damp proofing to be installed during the conversion, as the existing garage routinely has a single skin design for walls and floors, which was not designed to be in accordance with building regulations for habitable rooms. This damp proofing will need to be put into walls and floors. Furthermore, the roof of the garage conversion will require water proofing. The damp proofing for the floor of the garage conversion will in most cases be achieved by utilising 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 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 have already been damp proofed, but this might have to be updated as part of the conversion in order to meet current building regulations. The walls will need to be damp proofed in order to protect the brickwork from rotting slowly as moisture sets in. This can be performed by either applying damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are already in the garage. Damp proofing is an important 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.
