Preparation: The surface of the affected area is cleaned and prepared for the injection. This may involve removing any loose mortar or debris. If you suspect that your property is suffering from rising damp, you should have it inspected as soon as possible before it worsens. You can use Document C as your comprehensive guide for damp-proofing-related regulations, and some of them are as follows: In some cases, the DPC injection is distributed at a faster rate than in others. To help you understand why, we’ve listed the primary factors that affect how long the process takes and even how well it works:

They don’t need any particular setup and are widely utilised to keep moisture from rising through the walls and generating dampness. The DPC cream that you use will have detailed instructions which you should follow. These should include information about the depth to which the chemical damp proof should be injected, but if not the above guidelines will suffice. What is Needed to Inject a Damp Proof Course Products and Tools Required In some cases you are better off using an Air Gap Membrane instead of sand and cement – Information and advice on these membranes and how to use them can be found here.At Timberwise, we have seen past work from local tradesmen, without the right damp proofing training, that have made common mistakes that have led to property owners having worse damp problems than they originally had before.

If you are in any doubt about how you should inject DPC cream for an effective damp proof course then you should consult a specialist damp proofing company. The removal and replacement of internal salt contaminated plaster is an important part of an effective damp-proof course. Salts left behind by rising damp are hygroscopic and can cause future staining independent of any issues with structural dampness. Seal the injection holes: Once the cream has been injected, the holes should be sealed with a suitable filler to prevent the cream from leaking out.Nonetheless, as you might expect, this method causes more structure distortion than DPC injection. Lower External Ground Level Regularly monitoring the walls to remain dry is important to ensure that the damp-proof cream is effective and to identify any issues as soon as they arise. Damp-proof creams proved to be one of the most effective materials for dealing with rising damp. Although it requires low pressure, it’s developed to travel deep inside capillary pores in the walls to form a strong horizontal barrier.

Drying: The damp-proof creams dry to form a water-repellent barrier that prevents moisture from rising through the capillaries in the masonry.Dryzone Damp-Proofing Cream is a water-based silicone cream that spreads through, and bonds with, sand;cement mortar. Any continuous sand;cement mortar line that has been properly treated with Dryzone becomes a damp-proof course. Due to the fact that it is a high strength cream, Dryzone delivers over 5 times more active ingredient to a wall, over a wider area, than other low strength competitors, making it longer lasting and more effective. How Dryzone is Applied These factors can affect the remedial work that is necessary – with your own meter and some technical advice you can minimise any costs involved in successfully injecting a new DPC.
