Damp can be a persistent issue in many homes, especially in regions like Bournemouth, Poole, and across Dorset, where damp conditions and rainfall can make properties more vulnerable.
Preventing damp is essential for maintaining the health of your home and protecting it from issues like mould, peeling paint, and even structural problems. Choosing the right damp proofing method can make a huge difference in keeping your property safe. We help you understand the best damp proofing methods available, from traditional to modern approaches, to keep your home dry and comfortable.
Why is damp proofing important?
Mould and mildew growth
These can harm air quality and trigger health issues, especially respiratory problems.
Damage to walls and plaster
Damp can lead to bubbling paint, peeling wallpaper, and deterioration of wall materials.
Structural weakening
Persistent moisture can weaken a building’s structure, which may lead to costly repairs in the long run.
Top damp proofing methods
Here are the most recommended methods for damp treatment, each suited to specific types of damp issues.
Damp Proof Course (DPC) Treatment
A Damp Proof Course (DPC) is a long-established method for controlling rising damp. This involves adding a barrier layer within the walls of the building to prevent moisture from travelling upwards through capillary action.
-
- How it Works: A DPC is usually installed at the base of the walls, where a barrier – typically a thick plastic or bitumen layer – is applied. This barrier stops water from rising through the wall materials.
- Best for: Rising damp, especially in older buildings that may not have an original damp proof course or have a deteriorated one.
- How it Works: A DPC is usually installed at the base of the walls, where a barrier – typically a thick plastic or bitumen layer – is applied. This barrier stops water from rising through the wall materials.
-
- Installation: DPCs can be installed during construction, but if you are retrofitting an older property, a specialist can inject a chemical damp proof course. In areas like Bournemouth and Poole, where many properties are period homes, this is a common solution.
Injection Creams
Injection creams are a popular, modern approach to damp proofing. These creams are easy to apply and can be effective in homes with rising damp.
- How it Works: A specialist drills holes along the base of the affected wall and injects a damp proof cream into the mortar. The cream spreads and creates a water-repellent barrier, preventing moisture from moving upwards.
- Best for: Internal walls with rising damp issues, especially where a traditional DPC isn’t present.
- Advantages: Injection creams are minimally invasive, making them ideal for properties with intact interiors.
- Best for: Internal walls with rising damp issues, especially where a traditional DPC isn’t present.

Damp proof membrane
- How it works: These sheets are installed on the wall or floor surface to act as a physical barrier, preventing water from moving through. In addition, they can be combined with other waterproofing solutions for basements and cellars.
- Best for: Walls, floors, and below-ground areas, especially useful in basement waterproofing.
- Advantages: Damp proof membranes offer effective moisture control, and their durability makes them a long-lasting solution.
Waterproof Coatings and Sealants
Waterproof coatings are liquids applied to surfaces to create a seal that repels water. While not a full solution for damp-proofing, these coatings work well as an added layer of protection.
- How it Works: A waterproof coating, such as bituminous paint, is applied directly to walls or floors, creating a water-resistant surface.
- Best for: Supplementary protection for areas already prone to damp.
- Advantages: Ideal for areas that need extra reinforcement and quick drying protection.
How to choose the best damp proof method for your home
The best damp proofing method will largely depend on the specific issues you’re facing and the type of property you have. Here are some things to think about when selecting the right approach:
- Identify the type of damp: Rising damp, penetrating damp, or condensation each require different treatments. Rising damp typically benefits most from DPC or injection creams, while penetrating damp might require a damp proof membrane.
- Consider the property’s age and Location: In areas like Bournemouth and Poole, older properties are more susceptible to rising damp due to their original construction, which may lack modern damp proofing. Newer homes may only need waterproof coatings for minor damp control.
- Consult a professional: A professional damp survey can accurately diagnose the type of damp and recommend the best course of action. They can also ensure the right installation, especially for more intensive methods like membranes or DPCs.
FAQs
1. How do you know if you need damp proofing?
Common signs include damp patches, mould, musty smells, or bubbling paint on lower walls. If you notice these, it’s wise to get a professional assessment.
2. Is damp proofing worth it?
Absolutely. Damp proofing not only protects your property but can also save you money on expensive repairs caused by untreated moisture.
3. Can you damp proof without removing plaster?
Yes, some methods, such as injection creams, allow you to damp proof without removing plaster. However, severe damp may require plaster removal to treat the wall thoroughly.
4. How to damp proof a wall from the inside?
Injection creams and damp proof membranes can be applied to interior walls to block moisture effectively.
5. Can you put a damp proof course in an old house?
Yes, and many older homes in Dorset benefit from adding or replacing a damp proof course. Retrofitting a DPC is a common solution for older buildings affected by rising damp.
