Did this to my house just over a year ago now. Has stopped our kitchen wall crumbling from the bottom up on the inside. I agree with comments that there is often a "root cause" to also deal with. But I didn't fancy tearing my driveway up so if this sorts it for at least a few years until I can then sounds good to me! (I have no reason to believe it won't last much longer). Cheap and easy to do.

[@geoffhunt6646]

Most modern damp proofing chemicals work in theory and this is a very good demonstration of how some can be applied by any non qualified person to walls with no plaster finishes or floor and wall joint problems. I do feel that for balance Roger should clarify how he determined the wall was actually suffering only from rising damp as this is the main reason why so many applications and interventions go wrong because of misdiagnosis. I think Rogers assessment is probably right but he has years of experience. The take home is this: once you have accurately diagnosed rising damp it is relatively easy to resolve but the cost and assessment to know it can only be rising damp is a bigger issue. I agree that Dry zone is a great product in the right hands and is a good remedy if only rising damp on bare walls is confirmed by proper assessment.

[@thomasalexander1277]

Hi. Thanks for the video. A few questions. Does this work for brick wall only, i.e. can the same technique be applied to a breeze block or a cinder block? If yes, do you still need to drill at 120mm intervals - into the block itself and not the mortar joint as it may be? Can you fit these from the outside of the house? Also, if there's an old failing waterproofing membrane, should I drill above or below it? Cheers.

There will be more on damp soon. This chemical is well proven to stop the passage of damp through the mortar course. In stone you have to find a mortar bed and because of the non uniform line it is a question of putting in a couple of lines.

Hi Roger, I am doing my wall right now. However, I m bit confused regarding hight above the ground. My wall is bit on slope. So, I decide to do it above 300 mm to maintain the same level throughout. Do you think it does have any effect on its functioning? Thanks for your response

[@MattsNerdWorld]

Hi Roger. Why did you start so high internally. Surely the 150mm dictates above external solid ground level not internal. If the external is the same this needs to be lowered to 150mm below internal and the dpc inserted just above internal solid floor level. This is also the case indicated on safeguards site. Also any bridging external render would need to be altered.

[@SkillBuilder]

Matty This is a wall we used as a demonstration and it was intended to show the rods and how they work. The ground on the other side was high and there is nothing we can do about it. Every single wall needs to be assessed on its merits. In this case the access is from one side and it is solid so placing a rod so low would mean it was less than 150mm above ground level. If it had been a cavity wall I would have tried to drill from both sides at different levels. I think sometimes you have to accept that the situation is less than ideal and in this case drilling and filling two courses may be the best solution. The guidelines from Safeguard cover a lot of variation. Back in the days of silicone fluid we used to drill and pump under pressure and a lot of the fluid finished up in the cavity. It was far less effective than these rods.

[@MattsNerdWorld]

Ok buddy sorry. Didnt want someone just copying and not getting the outcome they wanted. Good content as usual mate.👍

[@officedotie]

Thanks Roger your video mentions a cream at first then you inserted rods so i presume its the rods ill use ,also you said to drill every perp joint and the vidoe appears to show you drilling shorter than that, the manufacturer suggests every 120mm 6 inch , so i am a bit confused any chance of a clarification please ,

[@theondebray]

Firstly I would go around outside to see the possible reasons for the damp, & what could be done to alleviate the ingression, as I have done on a number of properties.

[@theondebray]

@Akshay Mhatre Sure. Check ground drainage all round, are there areas with standing water? Any blocked drains or soakaways? Has the damp proof course been bridged i.e. cemented or built over? Then I would dig a French drain all round, as necessary, dig a trench at least 15" deep Fill the lower half with shingle, the upper layer with gravel. Also, with a large fence post borer, bore a deep hole & see if you find the water table (water level in the ground). I have successfully bored a 3' deep hole, filled it with a perforated 4" plastic pipe; water drains into that & can evaporate in summer. If the water table is too high, you may have to construct an underground drain from that to take the water away from the house. If you are on a flood plain, well, move or buy a boat!

[@GavinLawrence747]

Absolutely love this channel and Roger, but personally I wouldn't be using these types of products to deal with damp. Do we know what the cause of the damp exactly is in this case?

[@gdfggggg]

The damp is there because there is no damp course. In period houses with solid floor, evaporation relied on airflow. This wall looks painted but maybe limewash (which is ok). The paint will aid the rising of damp. Modern living tends to facilitate damp as people want to keep vents shut to keep the warm in. There’s two ways to prevent this damp: 1. Rip up the concrete floor about 2 feet below ground level on the inside and outside, install a wooden floor in its place with lots of ventilation underfloor to outside; this will allow the rising damp in the wall to evaporate before it gets to inside floor level or 2. Install a injection damp course like roger is doing here. So 10-15 grand or a 500 quid injection course..

Yes, absolutely Stormdry is the same stuff

[@SkillBuilder]

Here is an interesting blog to balance out the argument. Rising damp is a myth, some say. Not many really think so; that would be stupid, but those who believe this nonsense seem to have the ear of the press and the ear of RIBA and RICS too. So instead of being drowned out by howls of derision from the those who really know about these things, they gain publicity and even a bit of notoriety too. Yet every day - yes every day, rising damp causes damage to our housing stock. It causes salting of brickwork, wet rot in floor joists bearing into affected walls, perishing plaster surfaces and even increases heat loss at the base of walls. Now then, you may disagree with me. Perhaps I’m just spouting an opinion too, like the ‘myth pushers’, but no, I state facts, facts proven time and again by me and importantly, by people who have really studied the phenomena scientifically. The internet is full of papers which detail various trials and careful studies done, in an effort to quantify the nature of the problem and analyse the effectiveness of treatments. They are being ignored. Who cares? Well we all should be worried, because when people read something in the papers they tend to believe it. If building preservation ‘experts’ generally agree on something and one or two of them suddenly start babbling an unsupported view, with no proper evidence, the papers like to publish it; conspiracy and corporate culpability sells so well. Unfortunately the readers get the information in an unbalanced way. They then become prey for all sorts of crackpot ways of dealing with their ‘mythical’ rising damp problems. As a result, I see people turning away from proven chemical damp-proof courses, just at the point when the technology of these systems has begun to deliver much better results. You see, chemical DPC’s have a bad press, because too many were installed improperly, by badly trained and sometimes quite iffy installers. Often no plastering was done, so the nitrate and chloride contaminated plaster just sat there; soaking up more humidity and the walls never dried out. Many DPC’s were installed for the wrong reasons; they can’t eliminate condensation or penetrating damp, or rising damp; if the cavity is blocked. This is not the fault of the material or proof that rising damp does not exist - it is the fault of the installer or the surveyor involved - or both. Now that we have better training and the advent of DryZone DPC injection cream, standards and success rates are far higher. This is good - but because of the bad and completely unjustified attacks on the whole premise that damp rises - customers are being bamboozled into trying unproven, unreliable and generally more expensive ‘cures’. So this is where the MMR scandal link is. The scandal was caused by poor and unproven opinion being disseminated as science fact. Before long, others jumped on the bandwagon and thousands of parents (many of the them middle class Sunday paper readers), decided that young Rupert and Felicity shouldn’t have the nasty jab. This directly caused the severe illness of many other children and eventually those who had promoted this were shown for what they were - the main doctor was struck off the medical register. In my opinion RIBA and RICS members who seem to support this current ‘myth’ nonsense should have a read of some proper evidence. As professionals we have a responsibility to give good advice to clients; advice based on facts; advice based on knowledge. Opinion is no substitute for fact; experience is no substitute for knowledge. Dry Rot.

There has been numerous scientific tests to show that rising damp is impossible however, using a chemical in the brickwork will usually correct the damp issues.

Looking for a house in Northern Spain. I feel like 3/4 of the houses have shown signs of rising damp. Glad to know it isn't necessarily something that should scare me away from certain houses in my search.

[@SkillBuilder]

Rising damp seems to be a very common thing in Spain. They don't always incorporate damp proof courses and they build with Porotherm blocks which are porous clay

[@TravelingBuildingGrowing]

@@SkillBuilder I had no idea what I was looking at until I researched "can you fix wet walls" basically. That's when I read about rising damp and DPC. As you state it is incredibly common. Thankfully the house I have settled was refurbished in 2004. Not sure they included a DPC. It doesn't seem to show signs of rising damp, fingers crossed. Though I can at least find comfort now knowing it's treatment seems to have a good track record.

Thanks Roger. Would you not damp membrane above the rods aswell, just doing some in my home dont want to do the finish and find the moisture re appears. Would it be ok with just rods?

The rods work but if there are salts in the wall they will draw moisture out of the air. A tile backer board dot and dabbed will help a lot.

Brilliant video. Is this method suitable for breeze block by any chance?

[@completepreservation]

Hi Roger I love your channel but this advice isn’t correct. Green algae stains are not from rising damp, and what happens to the wall below the damp proof course.... it will stay wet! So what is the point putting in a dpc? A more suitable solution would be to remove the modern paint to allow evaporation so the wall gets to dry down. All damp diagnosis and repairs should follow BRE DIGEST 245, and BS 6576 2005.... and this doesn’t.

[@gdfggggg]

Ross Charters your argument is a contradiction. You say the green algae is not from rising damp, but you also tell him to remove the paint to allow evaporation so the wall drys down. You’ve been watching to many Peter Ward video’s....

I have a cinder block wall on concrete foundation, can this product be used still or does it only work for brick wall structures?

[@nigelsansom2407]

But... number one priority MUST be to find the source of the damp and remove it. Below a certain moisture content there is no mould that can survive. The great majority of cases of decay and deterioration in old buildings are down to either neglect or bad alteration which has at some point facilitated water ingress. There is a massive industry around ‘rising damp’ and ‘wet rot’ but nothing works as well as identifying and removing the problem, reducing the moisture content and keeping it so. It’s as true for timber buildings as it is for brick built. Do check out literature by Brian Ridout or basically any KZbin video by Pete Ward. Sorry, this is not an attack on you. I really like your videos, especially the ones with that little chippy in... 😀

[@SkillBuilder]

Nigel No problem at all and in the longer video we discuss all this and more. The fact is that this building has no damp proof course so that is an immediate and obvious reason for putting one in. The other thing that people overlook is that decay is the natural and default status of anything and everything.

[@KennyEvansUK]

If you've not got a damp course, it will be the ground, that's the number one cause of damp bricks below 30cm.

[@Honeycrumblesmum]

Hi Rodger, I’ve just brought my first home, there is loads of rising damp and salt issues. Apparently this has been done at the property (1987 and 2002) is it worth me doing this again?

[@SkillBuilder]

Octavia I think two attempts to solve the problem is probably enough. The salts often draw moisture in from the air. It is one of the reasons why they tank the walls but if the tanking is not salt resistant there will be problems. Often it takes years for the salts in walls to find their way out. Can you send me lots of pictures of the inside and outside so I can have a look. Show me the bits which aren't damp as well as those that are. Here is an extract from a document relating to this problem To begin to examine the scope of this problem and the effectiveness of various treatments, 24 historic buildings in Adelaide were examined, with a focus on the building materials, historic interventions and current treatments applied to treat rising damp and salt decay. Analysis of 90 samples found high levels of sodium sulfate, sodium chloride and sodium nitrate in cellars, ground water and building materials, suggesting a clear example of rising damp. Samples of disintegrating masonry, depth profiles acquired by drilling, poultices and damp proof courses (DPC) were analyzed by Ion Chromatography (IC) and Environmental Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy (ESEM/EDS). Mercury Intrusion Porosimetry (MIP) and capillarity test were carried out in the building materials and DPCs showing that porous materials with high porosity, small pores and low strength are more prone to salt weathering. The City of Adelaide is a natural laboratory for comparing and analyzing different treatments of salt-laden masonry, with hundreds of treated buildings of the same age, in the same environment, and with similar building materials.

[@LukeStratton94]

Roger, I’d be interested if you could do a video or podcast with your thoughts in relation to Peter Ward’s opinions. He’s not an idiot and to be honest I’d rather side with him than a damp proofing contractor, but I think we’d all like to hear your opinions in response as he makes a lot of good points.

[@SkillBuilder]

Hi Luke I actually made a programme for BBC Watchdog around 18 years ago all about the misdiagnosis of damp and the mis selling of remedial treatments. I concur with a lot of what is said about looking for other courses but there are cases where a remedial damp proof course is exactly what is required. This house with no dpc is a case in point. Where is has been extended it has a dampproof course and the walls are not damp. I think that the problem we are looking at is really one of polarisation. People think that you have to side with one particular camp which is ridiculous. My view is a lot more balanced than that of Peter Ward or Geoff Howell. I understand the need to make controversial statements and to take a stance to get yourself recognised but the truth is often a lot more nuanced. In my teens I worked for a master bricklayer who told me that the worst thing that ever happened to the building industry was cement and we used a lot of lime mortar in the restoration of London's historic buildings so I know the arguments. I will tackle this subject in the very near future but, for now, I will say that the introduction of the damp proof course was a change for good and anyone who tries to suggest that it was a retrograde step and that a building without one is somehow better off is talking nonsense. Unfortunately there are many such people running around. You even get people who say "Look at Venice" they don't have damp proof courses. Anyone who has been to Venice and spent time looking at their buildings will see and smell damp. It is also no accident that some of the leading experts in remedial damp proofing are Dutch.

[@stevenmurray6359]

@@SkillBuilder most old building throughout the country are now suffering damp issues. Houses built in genuine lime mortar need to have a complete lime cycle. If they don't moisture builds up very rapidly. Buildings in Venice have been messed about with as much as ours. The skills your old teacher taught you are quickly vanishing. As is the understanding. I can assure you once you take away modern materials from a building the damp goes away. At a rate of an inch per month. I truly hope this practice stops very quickly and old buildings are returned to how they once were. Not for my bank ballance, but for home owners bank ballances.

[@SkillBuilder]

@@stevenmurray6359 There is a degree of truth in what you say but make no mistake there was damp in old houses. Anyone who reads Pepy's and others of that era will know that houses were cold, damp, inhospitable places and the only respite to a lifetime of living in such conditions was strong drink , to which a great proportion of the population succumbed.

[@stevenmurray6359]

Yeah they didn't have glass in the windows and straw on the floor. Victorian houses had green shield wallpaper that was made arsenic we know all that. Draughty well maintained old houses last. We can now introduce draught through controllable electrical units. We can allow moisture control of building fabric through hot lime mixes and clay paint. We can control heat. We can lower external levels keep on top of maintenance the linseed oil paint is amazing. If you and others keep using cement and chemicals home owners will have to pay me lots of money to reverse it. You guys are excellent modern builders. I watch you and Rob all the time but unfortunately on this one you are very wrong. Not just you, there's that god awful man from core conservation going round selling all sorts of nonsense.

[@propertymaintenancesouthwe3111]

Like your videos Roger, I’ve learnt some useful tips from you, I’ve got a couple of questions regarding this video : If there was no dpc of any description already in place why didn’t the property have a damp problem in this location from when it was originally constructed, surely it wouldn’t take capillary action over a hundred years to get to this condition ? (Unless of course the other side is external and floor level has been raised causing a bridge of original dpc). Also, you drilled 2 courses of brick up from internal floor level and dpc injections work vertically along the wall, so what’s to stop damp rising/forming visibly on wall below your newly injected dpc ?. I may be missing something but don’t see how you wouldn’t have the same damp strip 150mm or so below your liquid dpc injection. And I agree, I think peter ward is wrong about capillary action too...

[@pageboy1974]

Exactly, totally agree with your point about damp below the new injection point. I suppose it is more damaging to a lime mortar than a cement mortar wall.

[@ealingbadger]

@@SkillBuilder Controversial or not, it's hard to argue with his piers in the cellar. There were others involved at the time as well (slaves, um, I mean students) to help build the piers for example and who presumably were also pressed into service to take the measurements and write up the results as a part of their studies. One would have to be peculiarly self-deluded to get away with claiming results contrary to the reality of what actually happened in the face of all of those extra pairs of eyeballs. I'm not just trying to be awkward. It annoys the hell out of me that, despite many dozens of hours of study and personal (bad) experience at the hands of the so called "damp wallies" I am still very much struggling to decode just who is telling the truth, the whole truth, and nothing but the truth in the whole dampness thing.

Even after watching Peter Wards videos i had to use this stuff in my house because there is a water source that Thames water claim is a "water table" under my house that regularly fills my basement. And guess what, it's been tested as chlorinated water!!! .. Thames still deny a leak. In the meantime my 130 year old house is rotting away. No amount of ventilation or repairing mortar with lime mortar will ever stop the water ingress or the damage it's causing. So I called damp wally and he said 10k to do what I did myself, just as Roger shows in this video, at a cost of about £300 to cover the perimeter of the house and for the first time in 3 years I have dry walls!!! At least above the floor level...

Legally speaking you do need approval from your neighbour before drilling into a party wall as the wall is owned by both parties. There have been a few cases of legal disputes where one side has drilled, it has forced damp up the wall of the neighbouring property and they have ended up with a big problem. It is very important to understand the legal situation before drilling into a party wall. you can see the potential for porblems when the wall is being drilled a long way but not the whole way, there will still be a section not treated. Then what if neighbour does same, you end up with dozens of holes in the brickwork! It is obviously better to get it treated from both sides on a party wall.

I am sure that two neighbours with rising damp in a party wall will both want a solution. I love the idea of forcing damp up the wall by treating half of it. I wonder what the 'rising damp is a myth brigade' have to say about that.
