Damp Proofing in Portland

Extensions such as garage conversions will typically require supplementary damp proofing to be added through the conversion, as the existing garage routinely has a single skin design for walls and floors, which was not built to comply 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 of the floor of the garage conversion will usually be performed 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 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 a few garages, the walls have already been damp proofed, but this may need to be updated as part of the conversion in order 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 is done 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 should adhere to, therefore is it vital to make sure that your garage conversion incorporates suitable damp proofing methods.
