Damp Proofing in Romford

Extensions such as garage conversions will typically require supplementary damp proofing to be added as part of conversion, as the existing garage will often 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 will need to be put into walls and floors. In addition, the roofing of the garage conversion will require 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 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 a few garages, the walls will have already been damp proofed, but this might have to be improved as part of the conversion in order to comply with current building regulations. The walls should be damp proofed to be able to safeguard the brickwork from rotting gradually as moisture sets in. This can be performed by either employing damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls that are 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 important to make sure that your garage conversion makes use of appropriate damp proofing methods.
