What is a damp proof course injection and Silicone?
Damp proof course injection and Silicone is a technique for damp proofing, wherein a silicone-based cream is inserted after holes are drilled into the masonry of a property because of capillary action. The aim of this process is to prevent rising damp.
Such an injection is ideal for brickwork properties where a DPC or damp proof course has never been installed earlier. It can also be used when a failure in a prevailing damp proof course is detected.

Rising damp can be stopped by using damp proof injection
One of the costliest forms of damp to be fixed is rising damp. At the same time, since it is a severe issue, you should get the job done in a proper fashion. The process should be started with a proper professional diagnosis so that possibilities of other kinds of damp can be ruled out entirely and also to ensure if the installation of a new DPC or damp proof course is really required. The problem can usually be fixed by installing a fresh damp proof course.
A damp proof course can function similar to an impermeable barrier, as well as prevent the property from getting damp due to the increased groundwater level. Re-plastering according to an accurate specification is required for the treatment of salts and also to stop the reappearance of damp issues.
Treatment for rising damp
Injecting a chemical DPC is undoubtedly one of the most effective, cost-efficient, and fastest treatments to cure rising damps. A silicon-based cream is injected into drilled holes in this process. Thereafter, the chemicals pass the masonry and also form a barrier to repel water. A major merit of this kind of damp proofing technique is that the injection is also effective in walls which have been under the attack of severe water saturation.
Damp Proofing Can Help Prevent
- Rising / Penetrating Damp
- Ingress of Water
- Salt Crystallization
- Plaster Breakdown
- Damp Staining
- Wet Rot / Dry Rot
Find out whether there is a damp-proof course or not
This is the first step that you should take. The presence of a damp-proof membrane and DPC to stop the groundwater from soaking into the floors or walls of ground-level should be checked. Also, check whether your existing damp-proof course has been damaged or not.
Insert or repair damp-proof course
A damp specialist or a builder has to first drill into the wall and inject a cream which is damp-proof so that it can function as the new course. It is the most widely-used remedial action for the damaged or missing course. In fact, these days you will come across a number of gels and chemicals which can be injected into your walls so that an artificial DPC can be created.

How damp proof injections work
These injections have been designed in a manner that it can be inserted deep into the walls. Also, the chemicals used in a damp proof injection is highly consistent in nature so that silane, its active component, can be absorbed properly before drying. It is precisely this that creates the barrier to repel water. Silicone or DPC creams can take a maximum of six weeks to cure the damp fully and then create a fresh DPC.
Re-rendering and re-plastering after injecting silicone
When the damp proof cream is injected in the affected area, it is just the beginning. Re-plastering should be done internally. Also, it is advised that the re-plastering works are delayed so that drying occurs for the longest possible period. At the same time, it may not be possible always. As such, products such as the PermaSEAL tanking and damp resistant membrane kit may be used to re-plaster.
Additionally, re-rendering should be done according to a particular specification so that salts can be stopped from getting transferred into the fresh plaster. The boreholes should be made good externally with cement and sand.
Purpose of re-plastering after injecting a chemical DPC
Groundwater constitutes chemicals like nitrates and chlorides, which can rise through the masonry wall’s pores. Huge quantities of these salts can start getting accumulated over time within the plastered surfaces and masonry. These salts stay even after the elimination of the water source.
Such ground salts are hygroscopic in nature, meaning that they have the moisture absorbing capacity from the air, particularly when the weather condition is humid. The salt makes the contacting decorations and the walls to stay damp even after a new DPC has been provided.
Hence, it is a necessary requirement to replace the wall plaster in case you wish that the rising damp treatment adheres to the practice code BS6576: 2005 to install chemical damp-proof courses.
