What is Damp Proof Injection?

Damp proof injection is a highly effective and reliable method for treating rising damp in buildings. This method involves the application of a chemical damp proof course (DPC) which works by the liquid silane and siloxane components spread by diffusion into the masonry and react with the available silica to form a waterproof barrier. This barrier prevents moisture from rising up the walls, thereby safeguarding the structure from the harmful effects of damp. 

While damp proof injection may not be suitable for all types of properties, it is the most reliable and cost-effective method of addressing rising damp when it can be applied. Our team of specialists is highly trained to assess whether this method is right for your home or business.

When installed by a professional company this process should be backed by a long term guarantee.

Rentokil Property Care’s damp proof injection solution has several advantages that make it the preferred choice for rising damp treatment:

Identifying the early signs of rising damp is crucial to preventing long-term damage to your property. Here are common signs that you might need a damp proof injection:

• Damp patches on walls: Often at the base of walls, appearing as patches of moisture.
• Peeling wallpaper or paint: If the paint or wallpaper is peeling off from the bottom of the wall, it’s a sign of moisture damage.
• Musty smells: Persistent damp odors may indicate rising damp.
• Crumbled plaster: When plaster begins to crumble or break off from the walls due to moisture infiltration.
• Black mould growth: Mould on walls, particularly at low levels, is a strong indicator of rising damp.

If you notice any of these signs, it's important to contact a damp proofing specialist right away to correctly diagnose the issue and confirm if it is in fact rising damp.

We use a specially formulated damp proof cream, which contains saline (silane) – the most effective and concentrated ingredient available in the market for damp proof injections. This cream is injected into the masonry and diffuses into the wall's capillaries, forming a long-lasting water-repellent barrier.

Once the chemical cream penetrates the wall, it lines the capillaries inside the masonry, blocking any moisture from rising through. This protective barrier helps stop moisture from rising upwards, ensuring your property stays dry and protected from the damaging effects of rising damp.

The length of time a damp proof course lasts totally depends on the building structure and building materials used. Over time a damp proof course can deteriorate where others in similar aged buildings are still working.

After the damp proof injection treatment, it’s important to let the walls fully dry to allow the cream to work its magic. Typically, you should wait at least 4 to 6 weeks before redecorating, depending on the moisture content of the walls and environmental conditions.

Our team will provide you with expert advice on how long to wait before plastering or painting your walls. In some cases, we may use additional products such as tanking membranes to help with the immediate replastering process.

The cost of damp proof injection will vary depending on several factors, such as the size of the area to be treated and the extent to damage to timber in the affected area and the amount of replastering needed.
