water penetrationn throuh stone wall

[calvert]

I have water penetrating the wall of my cotswold stone house for the length of the chimney stack, enough to mop up into a bucket. The wall is only about 5 inches thick at this point. Its recently been repointed with a sand/lime/cement mix. Can anyone suggest a cure please? This wall is taking all the wind and rain

you need this http://www.johnstonestrade.com/default_majestic.asp?section=14&product=7

better than thompsons water seal by far,

followed by plioloite masonry colour if your house is painted, its an oil based masonry paint.

If your house is not painted, the water seal will eventually break down with uv rays

please by all means look into tawelfryn's info which i have no knowledge or experience of.

i know that solid walls are a problem (both rising & penetrating damp). the only way i know to sort is to tank the internal wall.

Which way to go depends on your needs.

have a search on the forum and ask if you need any more info.

The dilema is that there is the argument that walls need to breath to prevent damp etc in the house. The traditionalist people reckon that any chemical application outside will never work 100%

This may be of help.

Is the wall really only 5 inches thick where the leak is occuring ?.
I have used the KD-2 reactive powder on its own and it has quite impressive sealing capabilities on the negative side.
It does exactly what it says on the tin.

both products what I have recommended are micro-porous, in other words they don't let water in, but allow to breathe and let moisture out

Thanks for your help. I think I'll try the Stormshield when the weather drys up. The KD system looks good but I really want to keep the water out of teh wall completely.
