Just a link to a site I quite like.

Humbled me in several areas after I thought through what was said and what the reasoning was behind it.

Hope it helps.

Also, if the house is built correctly you don't need a DPC.
It would appear so! The web page said how they couldn't replicate the 1m rising damp; it appears the damp reached the first course and then exited through the lime mortar. Interesting stuff.

For balance a website from another consultant RTS

Some interesting points on rising damp http://buildingpreservation.com/images/stories/pdf...

I've been on a couple of training courses with him.

He, quite reasonably IMO, points out that a newly built lime wall will not act the same way as a carbonated 80 year old wall.

Ground salts are interesting (If you're interested in old buildings!)
Read it but got a bit lost a after a few pages with his bashing of the lad Jeff. What does he suggest as his cures?

Spent the day taking external concrete render off a 200 year old brick work today. We also dug out the usual offending soil level to below the internal floor level.

We patched an internal piece of brick work with lime last week to support it in preparation of todays activities.

It had stayed visibly damp since application but within an hour of removing the external stuff, the water level had dropped at least an inch!

Can't believe Im excited to see how far its dropped tomorrow.

Our 1700's solid slate walled cottage had been rendered both internally and externally with cement based products

I spent all of last week with a jackhammer removing the cement plaster and this week i have the plasteres in re-doing it all in Lime

Hope it works and is woth it

If I see an improvement i will be doing the same on the outside asap
Check out Anglia Lime Company, if you're still looking for stuff to apply. Im using their Thermalime product for a lot of my walls.
