Damp injections deliver long-lasting protection by penetrating the masonry deeply. Their effectiveness typically lasts for the lifetime of the building. What Is A Damp Proof Injection? In general, damp-proof injections are applied 150mm above ground level. This is the point at which you should start drilling horizontal holes 12mm in diameter and 10-12mm in depth. Do You Apply Damp Proof Injection on Internal Walls?

After a damp-proof injection cream has been installed, there are a few things you can do to help ensure that it remains effective: A damp-proof injection is a technique to prevent moisture from penetrating the walls of a building. This process involves injecting a specialised cream into the walls of a building to create a barrier against moisture, which can cause damp and mould to form. When it comes to damp proofing, you might find lots of jargon that can be perplexing. So, to help clear up any confusion, we’ll answer some frequently asked questions about the various types of DPC. What Is Membrane Damp Proofing?DPC should be applied to the joints between windows and doors to prevent precipitation from entering the building Multiple scenarios can result in this problem. As we previously mentioned, it could be because the pre-installed damp proof is worn out, but in other cases, poor drainage could be the culprit. In this article, we’ll go over everything related to this damp-proofing method so you can understand how, when, and why it’s used! What Is Damp Proof Injection? 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 Throughout our years in this industry, we’ve seen several cases where we had to fix failed projects that ended up costing more than if a professional had handled it from the start.

Once the damp proof cream has been injected into the walls of the building then re-plastering will then need to be carried out on the internal walls of the building. This process should be delayed for as long as possible to ensure there is enough time for the walls to dry out. When the rising damp case is severe, a physical DPM can be installed instead of a chemical injection. There are several things to avoid when injecting a damp-proof cream to ensure moisture penetration remains intact: Injection Cream (or other damp-proofing material): Expands horizontally inside the wall to form a water-repelling layerThese 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.

If this approach is not feasible the DPC must be placed at 150 mm above external ground level and the internal walls tanked below the DPC to prevent lateral migration of moisture/ salts. 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.

Insulate the walls: Proper insulation can help to prevent damp in your walls by reducing the amount of moisture that can penetrate the walls.No High-Pressure Injection Pump Required: Unlike traditional damp proofing methods, this injection cream doesn't require a high-pressure injection pump to deliver the solution. This helps speed up the installation process and minimize operator workload. This type of damp proofing has a lifespan of 20-30 years or can last as long as the building. Factors Affecting the Lifespan of Damp Proof Injection

To Avoid Health Issues: The dampness of a building can also cause health problems, particularly respiratory issues and allergies. 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. Once all the measures have been put in place then the damp proofing cream can be injected into the hole. The technician will first drill holes of approximately 12mm depth horizontally into the wall mortar joint. 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.

Inject damp-proof cream: A special injection pump injects the damp-proof cream into the holes. The chemical damp proofing cream should be injected slowly and evenly to ensure it spreads evenly through the wall and creates a continuous moisture barrier. To Prevent rot in the wood: Damp can cause wood to rot, weakening the structural integrity of a building and making it more susceptible to collapse. Injecting a damp proof course when there is a bridging of cavity walls. This will over time fill up with debris and can bridge the damp course, the moisture will pass through and cause damage.
