Damp Proofing in Sevenoaks

Extensions including garage conversions will usually require supplementary damp proofing to be added during the conversion, as the pre-existing garage normally 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 have 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 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 placed down either on top of the pre-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 some garages, the walls have been damp proofed, but this may have to be updated as part of the conversion in order to adhere to current building regulations. The walls will need to be damp proofed in order to protect the brickwork from rotting gradually as moisture sets in. This can be performed by either implementing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present 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 necessary to make sure that your garage conversion employs suitable damp proofing methods.
