Damp Proofing in Dorchester

Extensions such as garage conversions will typically require supplementary damp proofing to be added through the conversion, as the existing garage will often have a single skin design for walls and floors, which was not manufactured to conform to building regulations for habitable rooms. This damp proofing should be put into walls and floors. Moreover, 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 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 have been damp proofed, but this might need to be updated as part of the conversion to be able 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 applying 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 will need to comply with, and so is it necessary to ensure that your garage conversion incorporates appropriate damp proofing methods.

How quickly can I redecorate my walls after damp proofing has been installed?
