Damp proof injection

[chriselevate]

Hi guys,

Thinking about giving my kitchen a good treatment of damp proof injection. I've heard the internal render has to come off to 1.2 metres. Are the bricks then drilled and injected?

Is it easy enough to inject then? What is used?

I guess after this done then it's re-rendered and plastered?

Thanks any help you can give on this.

Thinking about giving my kitchen a good treatment of damp proof injection

Is this because there is actually a confirmed case of rising damp?
Or just because there is some other totally different damp problem?

It's a solid constructed wall with no damp proofing on atm. It seems to be rising.

Is there a way to confirm that something like dryzone injecting will sort it?

Thanks

Hi,

As Flameport has indicated, just because you have some low level wall dampness, you should not automatically assume it is rising damp. I would avoid doing any injection DPC work until you are are quite sure the dampness is from no other source including condensation. DPC's can take different forms. The apparent absence of one does not automatically mean that must be the problem.

Replastering to 1.2m is totally unneccessary unless the plaster has been damaged or affected by dampness. It is sometimes used by "specialsts" as a "catch all" solution to avoid call back problems if they miss an affected area of plaster.

I would suggest you dig deeper into the subject and explore all other reasons first. Get help from some-one recommended and experienced in dampness problems would be sensible, failing that, at least get a report from a specialist, but note that if the report seems over the top , it probably is! - It is not an area where you can easily get impartial advice.

Thanks for the helpful advice.

When we moved in we had a remedial report done and as a result they came and did the front room, around the bay and a few places on the front. A damp meter on that 5 yrs later and it's not come back.

The ground level of the kitchen (which is where I'm having current problems) is very similar to the inside level. A damp meter showed the room to be damp in the lower parts of the Walls and it looks like someone has used synthapruf to try and solve it.

A general builder said "I'll come in, chop it all away, inject it, render and plaster it".

Hmmm... not sure what to do.
