Damp proofing
Extensions including garage conversions will often require extra damp proofing to be added during the conversion, as the existing garage normally has a single skin design for walls and floors, which was not manufactured to comply 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 need water proofing.
The damp proofing of the floor of the garage conversion will in most cases be performed by utilising 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 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 some garages, the walls will have already been damp proofed, but this might have to be improved as part of the conversion in order to meet current building regulations. The walls will need to be damp proofed in order to safeguard the brickwork from rotting gradually as moisture sets in. This can be 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 a part of the building regulations that the garage conversion should adhere to, and so is it important to ensure that your garage conversion makes use of suitable damp proofing methods.

Damp proofing FAQs
You should make sure that all signs of damp have gone before you redecorate your walls. If you want to paint your walls with a water-permeable emulsion paint, you can usually do this after 1 or 2 months. For other types of decoration you should wait longer.
Signs of rising damp tend to be close to the ground, usually no higher than a metre. It usually works its way up walls in horizontal lines. Penetrating damp usually develops in patches and can often be much higher up. For more advice, speak to a damp proofing professional.
There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell. These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.
