Damp Proofing in Purley
Extensions such as garage conversions will often require extra damp proofing to be installed through the conversion, as the pre-existing garage will typically 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 should be put into walls and floors. Furthermore, the roofing of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will most likely be achieved 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 some garages, the walls have already been damp proofed, but this might need to be updated as part of the conversion to be able to adhere to current building regulations. The walls should be damp proofed in order to protect the brickwork from rotting slowly as moisture sets in. This can be accomplished by either utilising 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 ensure that your garage conversion makes use of suitable damp proofing methods.
