Is damp proofing a legal requirement?
Building regulations say that all new buildings should have damp proof courses to prevent rising damp and in some cases courses to prevent penetrating damp. Damp proof courses in walls should: Be at least 2.25cm above the bottom of a cavity wall cavity unless a cavity tray is installed.
Is damp proofing an air barrier?
While vapor barriers generally keep interior moisture from getting into walls, damp proofing keeps exterior moisture out of buildings. A damp-proof course is a barrier designed to prevent moisture from entering the structure through capillaries in concrete and masonry.
Can damp proof course fail?
A DPC may fail because it was not fitted properly or may fail due to deterioration, localised damage or bridging. If the DPC fails then your property may be suffering from rising damp. Rising damp is moisture which defies gravity and moves upwards through walls as a result of capillary action.
Is damp proofing toxic?
Damp-proofing chemicals should not be swallowed. In case of accidental ingestion:- Drink plenty of water, Seek medical advice, Do not induce vomiting. Solvent will remove natural oils from the skin, resulting in reddening and cracking with the risk of dermatitis.
Can you do your own damp proofing?

Can you do a damp proof course yourself?
Twistfix supplies its DIY damp proofing kit with everything needed for a do it yourself damp proof course to stop damp walls.

What is difference between damp proofing and water proofing?
Damp proofing is not a process that is intended to keep all the water and moisture out. Waterproofing is the most effective treatment as it keeps water in its various states from crossing a surface, therefore moisture from the soil, water vapour and water under hydrostatic pressure is efficiently barred.
How effective is damp proofing?
When correctly installed they are 100% effective. They do not suddenly fail. So never accept the option of installing a Chemical Damp Proof Course in one of these buildings – some simple investigation will almost certainly find a water leak, usually internal, and these are usually covered by your Building Insurance.

Stephen Boniface, former chairman of the construction arm of the Royal Institution of Chartered Surveyors (RICS), has told the institute’s 40,000 members that ‘true rising damp’ is a myth and chemically injected damp-proof courses (DPC) are ‘a complete waste of money’.
How long does damp proofing last?
Typically, a physical damp proof course lasts for 20-25 years and can fail due to it not being fitted properly or deterioration. If a damp proofing course has failed then this could potentially lead to rising damp.
How do you damp-proof a wall yourself?
The most common way to damp-proof a wall is to apply a damping resin, epoxy, or spray to the surface of the wall. You can also use plastic sheeting to cover exterior wood walls, or silicone to fill in gaps in masonry and keep dampness out.
