How to stop rising damp, easy DIY solution

[@CherDele]

Had damp and mouldy smell in my launge for years. After a lot of replacing plaster and keeping a window open all through winter months, I decided to rip up the floor boards. My DPC was old-fashioned slates. Broken and missing motar from joints and some of the slates had deteriorated. Thorough cleaning, then replaced broken and deteriorated slates. Repointed, then cleared a whole lot of damp dirt from underneath the suspended flooring. Let the area dry out for approx 1 month. Yeah, it was a long, hard, and messy job, but it was worth it. Replastered wall. Replaced damp skirting and floorboards. Sanded and varnished wooden floor. Damp walls and smell gone. Oh, I also had to dig up the concrete paving under the windows outside as it was higher than the airbricks. I replaced the rotten makeshift airbricks covering with clay airbricks. My launge has remained damp free and smells great for over 3yrs now. And i'm a woman in her 50s! I learnt almost all I know from these DIY videos. My thing is, have a go. You never know what you can achieve. The best thing is, you save yourself a fortune.

Damp will come through that plaster I promise you, there is no special coating to stop the damp, the coating will just peel and bubble off. In an old house (mine is 250 years old), the only sure way is to take out a section of the wall at floor level say 4 bricks length at time at ground level either one brick or two bricks thick, then with the hole clearance available dig out as much below ground which was under the bricks you have taken out, a breaker drill will do the job beautifully especially if you can break up the adjacent floor say 3 inches out and that will enable you to sideways dig out the old damp foundation rubble causing the rising damp. Having dug out your new foundation trench you have , now you have to put in there what you would use as if was a new house you were building, ie impervious materials, quality concrete, DPC and blue clay impervious bricks. This might sound like hard work but it's worth it. The best thing is that the layer you put in say 2 bricks high when dried off, will be totally dry and the damp brickwork above it will dry out at about an inch or 2 a month, even quicker if you want to use a fan on the wall continuously. A 4 brick section of the wall taken out at a time and it won't take long and in the end you know it's been done right and any plastering done above that new brickwork you know it will be good and dry.

Just put dry rods in the house I am renovating. It has a mixture of solid walls and cavity walls. I found many problems before installing the rods, and consider them "belt and braces!" There were redundant vents below floor lever that should have been removed when concrete floors were installed. Ground levels well above old slate damp course, slates on roof that didn't reach gutter, drainage pipes underground that were held together with parcel tape, damp courses bridged inside. Also concrete right up to house walls (my pet hate.) I dug 10 inches down and put a gravel trap around the house. Poor house has been sat in a moat for years! That was just the beginning, I could write a book.

Has it dealt with the symptoms, what about the cause. The damp will still be there behind it. I spoke with someone who did this and damp reappeared further up 4 or 5 years later. Hope it works for you.

[@popandu1170]

My guess would be gypsum plaster sealing-in the moisture causing the build-up of the wet. Solution: Remove all the gypsum plaster and replace with an appropriate BREATHABLE plaster and problem solved. It's amazing that people do things and are completely oblivious to what is actually going on around them.

You did a nice job. Be interesting to find out why that wall was getting damp, must be some water source underneath there.

The house is 90 years old so I think whatever damp proof course they used if any is now failing so damp is beginning to rise in a few places

[@slyteen2197]

The electric socket has been moved at some point and the affected area filled with bonding coat which is unsuitable for low levels where salts can be present. All that was needed was the affected area be chopped out and then patched with the dryzone express system or salt resistant render.

[@BrainFizz]

Just two points. 1. If you have to remove the plaster back to brick on a solid 9” wall anyway. Don’t waste money on an injection system, just get it plastered in lime. NHL3.5 will do the job, and dry in a similar tins to gypsum (which is trapping your moisture inside the bricks. 2. Rising damp doesn’t exist. Water travels down, either your ground level outside is too high (dig it out and lower it), idd red your gutter is overflowing.

[@spendtimesavemoneydiy]

But it is an internal wall, both sides are in my house, one side in living room and the other in the hall with no water or pipes anywhere near. The mortar behind the skirting boards was like damp soil and smelt like damp soil. A lot of people have said rising damp doesn't exist so why does every new building require a dpm and dpc?? I'm no expert that's why I sought advice from safeguard.

It’s a decent system but Sika also do an impregnating compound the appropriate holes are filled with the use of an ordinary caulking gun. A little bit of advice when using SBR as a bonding/sealing coat, damp the substrate firstly. The SBR is more easily absorbed into the substrate. Unfortunately gypsum is very water soluble, very. Better to use a lime based render as it’s also breathable.

​@@spendtimesavemoneydiy I've had a similar issue, internal wall, absolutely no way of water getting in apart from the ground allegedly.

Now moisture is low in the house and the issue has disappeared despite high rainfall. Likely same thing happening here... those bricks look dry similar to ours, even if the mortar is saturated, doesn't mean it's coming from rising damp, likely the moisture pooling on that wall is seeping into there.

This sorry excuse for a human is selling you snake oil! He does not have a clue about damp! AVOID AT ALL COSTS

[@adrienne7513]

Total rubbish.!! The damp is obviously being caused by the gypsum plaster layer that has been placed over the old original lime plaster. The lime allows moisture to breath out of the wall - the gypsum was locking it in. All that is needed here is for the gypsum layer to be removed or all taken down and the lime reinstated. Everything you did here is utterly pointless and has made the situation much worse. That wall will be saturated behind all that waterproofing in a few years.
