A damp proof course ( DPC ) is a physical barrier inserted into the fabric of a building to stop water passing from one place to another. This can be on a horizontal plane, stopping water rising up from the ground by being sucked up by the dry masonry above, or vertically to stop water passing from the outside of a building, though the masonry, to the inside. DPC's have taken many forms through the ages and one of the earliest forms was to use a layer of slate in the construction. Slate is still used but the less expensive plastic version ( below right ) is now more widely used.

A horizontal DPC is usually placed 6 inches above ground level and used in conjunction with a damp proof membrane which stops water rising to any part of the ground floor from the ground. A diagram of a typical ground floor construction can be seen below and you can see how a Damp Proof Course works in conjunction with the membrane to stop any water rising up into the building above.

Damp Proof Course Cross Section

In many older properties a non porous stone was used to build the first few courses of masonry but over the years this stone in many instances has become porous allowing water to be soaked up through it. It is not practical in most cases, to remove a course of stone to place a plastic, lead or slate DPC in the wall and new methods have been found of introducing a DPC where there is either none, or one that is broken in some way. These methods generally require the injection of chemicals into the walls and, on a larger scale, are better done by specialists as there are many complications which can arise as a result of saturated plaster and the measurement of the chemical being injected.

Now you can make repairs or add a DPC to small projects using a unique DIY method involving simple injection of a specialised cream using a normal sealant applicator gun after drilling 12mm holes to inject into!

DIY Damp Proofing - An Easy Solution

At last it is practical for home and amateur users to insert a chemical Damp Proof Course reliably, even in thick stone walls. This is because ‘UltraCure Cream’ has taken over from the high pressure injection of liquid.

The old injection technique was hit and miss - even the ‘professionals’ struggled with blow backs, loss of fluid via fissures and the difficulty of getting a seal in crumbling masonry. Your only option then, as a private property owner, was to pay for a Damp Proofing Company to carry out the work, including the inevitable expensive replastering. Now you can even obtain your own Product Guarantee Certificate after injecting your own damp proof course.

The new generation of UltraCure DPC Creams have appeared and for the first time private individuals and developers, builders and DIY enthusiasts can reliably and cheaply inject their own chemical DPC. Small jobs are no problem – the cream arrives in clean, sealed plastic, disposable cartridges, ready to fit into a standard skeleton gun. Nothing could be easier to inject – drill the hole, blow out the dust, inject – it takes about 1 – 2 minutes per hole and anyone can do it!

Information and Main Features of Ultra Cure Cream DPC

  • QUICK & EASY TO INSTALL– drill the holes, blow out the dust, inject. No special tools required
  • NO WASTAGE – Comes in a standard 'mastic' tube, ready to use and fits straight into your skeleton gun
  • LOW HAZARD – not even rated as irritant
  • SPILLAGE & MESS ELIMINATED – no liquids to spill or stain
  • NO ELECTRIC DPC PUMP REQUIRED – No electric pumps to hire or messy, smelly fluids just simple hand pressure only
  • DIY TECHNOLOGY  – advanced emulsion uses active Silicone ingredient economically (Siloxane and Silane, for the technically minded) without running back out of the holes

British Board of Agrèment- BBA Test Certificate No: 02/3961 - as used by the professionals. The BBA is a Goverment Approved organisation which has been testing building materials for over 30 years. Not all damp proofing materials have passed these tests - beware of cheap imitations. click here to View BBA Certificate.

Typical usage rates:

4.5 inch thick (115mm) single leaf wall - 1000cc (1 litre) per 9 metres, inject from either side

9 inch thick wall (230mm) double leaf solid or cavity - 1000cc(1 litre) per 4.5 metres, inject from one side or from both sides.

18 inch thick wall (460mm) solid or random fill - 1000cc (1 litre) per 2 metres, inject from both sides

Applying Quick Cream
As used by the Trade - Quick Cream is inserted into 12mm holes (400cc mastic tube type illustrated - uses standard skeleton gun)

How to Install a Damp Proof Course

First, check for high ground levels, leaking gutters and down pipes, water leaks.

1. Drill 12mm diameter holes at 115mm intervals in the mortar course (or via the brickwork, angled down to meet the mortar course) selected to be at least 150mm above outside or abutting ground level

2. Fit the extension nozzle to the cartridge tube and load into the skeleton gun

3. Inject cream from the bottom of the hole outwards until the hole is full.

4. Holes can be capped with mortar or fitted with a plastic plug

Plastic Fixing Plugs
Plastic tapered plugs for filling drill holes.

Walls and Skirting Board

Don’t forget to check the walls and skirting boards for dampness. If you click on the damp meter images above you will be taken to a section of the Property Repair Systems site where you will find detailed information on how our Damp Meters work and you will also be able to purchase and view our extensive range of meters for a great many jobs.

Replaster to a minimum of 1.2 metres internally, to our specification, using sand and cement and Rendapruf integral waterproofer. This will prevent 'salts' damage to plaster finishes and decorations.

Replastering is an essential job after inserting a chemical damp proof course – see our Replastering Project for detailed information. In some cases you are better off using an Air Gap Membrane instead of sand and cement – have a look at Membranes and then give us a call for help with your decision.

Air Gap Membrane is simply fixed with plastic plugs
