Rising damp

Sounds like bollix. Rising damp is a lot less common than some people would have you think. Condensation is far more likely. You can't tell the difference with your damp meter. And there are several things to look at before injecting a damp course.

The equipment can be hired to DIY it from tool hire shops too. Sometimes you don't even need the pump.

At 5 oclock in the morning I've just been watching one of those daytime property programs that is repeated in the TV teleshopping hours.



The property had a damp problem in one small area under the stairs. The expert comes in with his little damp meter and after a claim that it was worst reading ever seen a quote of £2K was forthcoming.



Cut to the next shot of someone hacking off the plaster and injecting some fluid into drilled holes in the bricks a couple of inches above the floor level. Judging by the colour of the free flowing dust on the surface of the exposed bricks and the colour of the drilled holes there was no damp in the bricks.

Drilling holes above floor level, funny I thought damp started at ground le vel

Porous brickwork absorbs a hell of a lot of liquid, and nobody ever seems to check how much (and of what concentration) they're pumping in. I've no doubt it can be effective in some situations if done properly, but mostly it's a waste of time and money.

You need the pump in certan circumstances.

The chemical is moisture repellent. It's pretty obvious when to stop.

They could always drill into the brick and see what colour the dust is, and whether it flows freely ... Simon.
