DAMP PROOF INJECTION

We often get asked by various people "does damp proof injection actually work?". The answer is always yes, but in the correct conditions and circumstances. We use two systems of injecting, depending on the fabrication of the wall concerned. We do everything that we can to not inject from the outside, as some companies do, leaving unsightly holes in the brick work. We wont perform damp proof injection, for the sake of it, or in the wrong circumstances. Just ask us, we wont charge to have a look......


This wall had previously been injected from the outside (very badly) where the person had not taken into account the adjoining internal walls. We were able, from the inside, to seperate the areas with rising damp problems from the rest of the internal walls to ensure a stable environment. The area was then painted to restore the area back to how it should be.
 
This is a good example of the damage that can be caused by salts being carried by rising dampness from the ground. We cleaned the paint off the wall, treated the brickwork with our antisulphate chemical, injected the mortar course with injection cream then painted with anticon paint to ensure no condensation issues arose in the future due to the lack of air movement, being a cupboard.
In this situatuon, the physical damp proof course had been badly tied in when the new door had been fitted.
We injected a vertical Damp Proof Course against the archetrave and tied in chemically to the existing horizontal physical damp proof membrane. This required hacking off and re-enstating the render and plaster, treating the wall with antisulphate, then decorating.
 
The external ground area outside of this property was up against the side of the property. We were able to inject a damp proof course eight bricks high from the inside before tanking the entire wall to ensure no moisture could penitrate through to the decorated surface. We also installed good drainage to keep any rain water away from the building in the future.
