Does it need a new damp proof course

[@TheIcebon]

Interesting video Ross, do old houses always need a membrane up against the internal floor, if there isn’t how would you get over it without ripping everything up?

[@completepreservation]

Cheers bud, and a good question 👍It does depend on the era and also the height of say the dpc in comparison to the height of the floor. Have a look at this video, where I think I go through some of it about the repair. kzbin.info/www/bejne/haPdf5aMe9api80

We had damp. Cavity wall insulation, high ground level, knackered drains, retro fitted concrete floor. Got rid of most of it, it was really bad on outside wall. Removed all insulation, lowered ground, sorted drains, re opened air bricks. Outside wall is bang on now. Just noticed a little bit on the side if the chimney breast. Not sure what to do about that. Considering drilling it and putting them rods in then a bit of tanking slurry. It must be rising, there's no other ace for it to come from! It's stressful.

Good for you for getting it sorted 👍 could be hygroscopic salts next to a chimney, with a bit of damp. Quite common to have damp near a chimney 👍 The area can be sampled to determine if it’s salts or and a moisture issue 👍

@@completepreservation I had all the plaster off when renovating the house and installing a wood burner. I treated all of the lower parts of the walls for salt. It looked like the house had been tanked years ago. I'm just wondering if the retro fitted concrete floor is breaching the dpc on the chimney stacks, or if the chimney even has a dpc. The rest of the house is an old felt type bitumen one. It had a wooden floor previously but I'm assuming it was removed because of rot and people not sorting the drainage out.

Have a read of this link, it explains it 👍 www.completepreservation.co.uk/what-is-bre-digest-245/

@@completepreservation thanks for that! Interesting read. I cleaned out all the cavities on the exterior wall and put in land drains around the house. Only thing I can think of from looking at that is the retro fitted concrete floor is stopping evaporation from the ground underneath the house and the old chimney breast is the place water is finding its way up. I'm not going to dig the whole floor up. I think I'll take the skirts off around the chimney, drill and inject it and then slurry the bottom 6 inch. If that doesn't work I might have to think about digging the floor up!. It's been a bit of a graft doing all this! I hand dug tonnes out from around the house to lower it and install land drains/ repair old pot pipes and u bends for the gutter down pipes. It's a million times better but this little bit that has appeared on the Chimney has really annoyed me! Thank you for taking the time to reply to me, it's much appreciated. Had a look through your videos, they're awesome BTW.

No probs bud... try and find the dpc initially. Remember hearths are typically laid to earth so are more prone to damp as no damp proofing was installed. personally I would never dig up a concrete floor for a small patch of damp..... the moisture content might only be 2%. It would seem somewhere along the way the damp repairs have been damaged in my opinion :)

Seems to always be drains

[@completepreservation]

Number 1 cause of damp at the base of the wall…. As you found out bud 👍
