Damp Proofing in Southwark

Extensions including garage conversions will often require supplementary damp proofing to be installed as part of conversion, as the pre-existing garage will often have 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. In addition, the roof of the garage conversion will need water proofing. The damp proofing for the floor of the garage conversion will most likely be achieved by employing a damp proof membrane. This membrane will 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 whether the floor will be a solid or a floating floor. In a few garages, the walls will have already been damp proofed, but this might need to be updated as part of the conversion in order to meet current building regulations. The walls should be damp proofed in order to protect the brickwork from rotting gradually as moisture sets in. This is done by either making use of 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 should adhere to, and so is it necessary to ensure that your garage conversion incorporates appropriate damp proofing methods.
