Damp Proofing in Stevenage

Extensions including garage conversions will typically require additional damp proofing to be installed as part of conversion, as the existing garage will often have a single skin design for walls and floors, which was not manufactured to be in accordance with building regulations for habitable rooms. This damp proofing will need to be added to walls and floors. Moreover, the roofing of the garage conversion will need water proofing. The damp proofing of the floor of the garage conversion will often be achieved by 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 if the floor will be a solid or a floating floor. In a few garages, the walls will have already been damp proofed, but this may need to be improved as part of the conversion in order to adhere to current building regulations. The walls should be damp proofed to be able to protect the brickwork from rotting slowly as moisture sets in. This can be performed by either making use of 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 integral part of the building regulations that the garage conversion will need to comply with, therefore is it important to ensure that your garage conversion employs appropriate damp proofing methods.
