Damp Proofing in St Agnes

Extensions including garage conversions will typically require supplementary damp proofing to be installed through the conversion, as the existing garage typically has a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing will have to be put into walls and floors. In addition, the roofing of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will in most cases be performed by using 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 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 might have to be updated as part of the conversion to be able to comply with current building regulations. The walls should be damp proofed in order to safeguard the brickwork from rotting slowly as moisture sets in. This is accomplished by either using 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 should comply with, and so is it necessary to ensure that your garage conversion employs appropriate damp proofing methods.
