Browse Forums General Discussion 1 Sep 29, 2019 10:34 pm Ok quick question, I need to damp proof a concrete floor in a circa 1980s house (bedroom). Short story we had a damp smell issue and moisture on the one wall - have established it’s a drainage issue outside so plan a massive job in digging out drainage running the corner of the house out to both sides (ground slopes towards that corner), we ripped up the carpet in the stinky room only to discover concrete has not been sealed and there is staining indicating moisture has been getting through. Which is probably why the underlay and carpet stunk! My question is can anyone recommend a damp rise/ damp stop or membrane paint from bunnings please (bunnings because we live rurally and that’s really the only place convenient). I don’t care if it stinks or takes a few days to cure (or whatever) l just want something that has good reviews and works. Bunnings sell a few and l want the best or second best option. Also there are some small (2mm -3mm cracks running along the floor in two areas) l suspect l need to fill these but with what - again recommendations are welcome please. If anyone has experience using any and can post please do. Re: Rising damp - concrete floor and slopes exterior 2Sep 30, 2019 9:41 am If your water ingress stops your slab will dry out and the mould growth will stop. You can wash down mouldy slab with vinegar and water and then dry out with a heater blower. To assist with smell removal you can buy and place packets of charcoal. Good ventilation and air changes are essential.

The exterior drainage job will be larger and therefore will be throwing money (the very little we have) at any labour we need there. Thanks for the responses, I am assuming the bitumen technique (waterproofing) is for the exterior when we dig out the ground around the two sides of the house to rectify the water pooling to the corner of the house - down from a slop hitting the corner. We hadn't considered this and I'll be looking at this now as it looks like it would be highly effective. As for photographs, here are photos of the interior floor post carpet rip-up interior. I need recommendations https://adobe.ly/2movGEs
So suggestions on what to do with this floor - as in filling cracks and painting or damp proofing would be greatly appreciated. Context here I am completely clueless on this kind of stuff. This is also was our nursery room so we have child in a makeshift spot the sooner I can recitfy the better please. ALL HELP GREATLY APPRECIATED Re: Rising damp - concrete floor and slopes exterior 5Oct 01, 2019 9:48 am Thanks for the photos At a quick glance you will need to locate the root cause of the water ingress outside or beneath the slab ie Broken agri or Stormwater pipes? and tackle that first With reference to the cracked slab use a level and check the deflection eg Sagging and hogging in a slab To be honest it's a job for a licensed plumber, search your community Council website, if there is a plumber nearby they might reply and assist with a free/quick coffee site visit.
