How exactly does a damp proofing injection work in preventing damp in your property and what is the method involved? We discuss all you need to know. We offer chemical injections with a 20 year guarantee as part of our damp proofing service.
A chemical injection is the quickest method available to damp proof your property and involves injecting a damp proof cream into holes that are drilled into the mortar joints of your wall. The cream is designed to penetrate deep into the masonry and lines pores and capillaries with a waterproof coating in order to create a barrier against rising damp.
Both internal and external walls must be prepped properly before beginning a damp proof injection. If you are already suffering from rising damp, then you may see signs of a tide mark both on your inner and outer walls. It is important that you remove all damaged and contaminated plaster before proceeding with the chemical injection, as well as remove skirting boards and radiators in the area.
Holes must be drilled to specific specifications, otherwise the effectiveness of the damp proof injection could be compromised. Holes should follow the mortar joints in a line and you should never drill directly into brick or stone.
Holes should be 150mm above ground level with a 12mm drill bit to a depth of 10-20mm from the opposite wall face and 120mm centres. This step is extremely important and can often be done incorrectly. It’s therefore wise to employ the help of a professional such as ourselves before attempting it.
Finally, inject the cream using a low pressure sprayer into the drilled holes in the mortar joints and leave to coat the pores and capillaries of your masonry effectively.

Air bricks may seem like small, unassuming fixtures, but they play a vital role in the health and integrity of your home. Particularly in properties with suspended timber floors, these ventilation tools can help prevent serious issues such as damp, condensation, and even structural damage.
Rising damp is an all-too-common issue that can affect homes of all shapes and sizes, especially older properties. It can cause problems like damp patches, mould, and even structural damage - issues that can be both expensive and time-consuming to fix.
