The stones under the windows and below the outside doors aren't concrete but natural bluestone. Belgium has been using its own bluestones since forever and Vietnam also has a good export of it, but of lesser quality (meaning easier to crack under stress). I work in construction in Belgium and currently have one that's soon to finish. I am the owner and also the builder so if you have questions I can always answer. And yes, my construction looks very similar to this too except a few minor details.

I'm an architect from Belgium. This is a very standard example of all details that are important in our trade. If you have any questions, feel free to ask.

Modern masonry uses a double wall separated by an isolated spigot avoiding cold bridges (so metal binding hooks are no longer used): an inside wall of prefab elements or half-bonded large quick-laying blocks (typically cemented rather than mortared) and an outside wall of decorative bricks, sometimes layed in decorative patterns (the more complicated the more expensive) or prefab brick-patterned plates.

And the removal of level crossings, replacing them with underpasses or bridges over the railways, so not impeding any motorist, and making train/vehicle collisions a thing of the past. The management of the excess water, and flooding, is light-years ahead of the rest of the world.

Hi, great piece. We lived in Belgium for 5 years. I was particularly impressed by each new building having a “grey water” system. All water falling on the roof was capturered and stored then recycled by using it to flush loos, water the garden and wash the car. I have always been amazed how much it must cost us in the UK to purify all water for drinking then we use it to flush the loo etc.. we need to change our building regs. and collect our grey water. We never had a water shortage even during a summer we had 40+ degrees.

I built my (off-grid) log house here in Finland. Pipe in pipe is common here and also in my place, and similarly, all electric wiring is in conduit. The house has underfloor radiant, but as it is a log house (with lots of windows) the walls don't have a high U value (even with triple glazed argon gas filled windows) compared to a regular wall. The ceiling and floor however are very well insulated. You may expect it takes a lot of energy to heat a place with essentially no insulation in the walls in a cold climate, but that's actually not the case. It's also fully off-grid, so I make all my own energy. Yes, a wood gasification burner and masonry fireplace is used, but the total amount of wood used is around 35kg per day when it's -30C outside. Outside of extreme cold weather, I make a fire every two days and this provides all the heating and hot water for four people - and the wife likes to keep the house at 23C or higher. Spring and early autumn is when a heat pump is used because at those times I generate enough electricity, while it is still very cold outside.

It doesn't take any heat from the body, it can conduct it .

Hi Roger, thank you very much for taking the time and trouble to investigate building methods in a different country with different expectations and standards. The first thing I notice on the one you show us is the height of the internal floor above the ground outside, that alone will mitigate the rising damp issues, much of which has always been cold wet external masonry draining heat form inside causing cold patches where condensation forms. What is most abundantly clear is that the erosion of standards in this country has lead to severe degradation of standards and quality, what little innovation that has come through has been entirely related to reducing costs to boost short term profits. Fifty years ago i was doing the roofs on a new build site near where I live that was run by an establish and well respected small company, the houses they built always sold at a premium both new and after a few years. The first ones I did had proper built roofs made with good quality sawn timber and the kitchens were all installed on asphalt floors that were throughout the whole ground floor. Over the next few months on of the bigger building companies took over and the next one I did had typical modern flimsy gang nail trusses and the floors were all just cement screed, the houses still looked the same when finished but under the skin were dreadful!. Still on sale at the same old price of course. Cheers, Richard.

In Belgium they use a strong 3/1 mortar mix to lay the bricks. At the end of the day, they rake/scrape the joints out for the pointing which is always done afterwards with a stronger (dryer) mix and a colour to choice. Therefore you don’t have any water absorption in your joints/pointing (because a a weak mix), your cavity stays dry and you don’t have any frost damage as water can’t penetrate through the joints. Unlike in the UK - a weak 5/1 mortar mix, damp cavity and every 10/15years repairing frost damaged bricks & repoint.

Wish I'd thought about it and asked my builder and plumber to do it for the house itself. Electric and data cables all in conduit or, when outside, inside barrier pipe. So much easier for modifications

One day I'll do a self-build so some I'm making a note of lots of these methods. I'm British but live in France. One thing I like is the pipe-in-pipe method, to individual shut-off valves. Also the separate fuses. We have a "Technical Room", basically a semi-external utility room, where the shut-off valves come to and all the electrical circuits as well. If only Building Regs would insist on Solar panels, a battery, and rainwater recovery storage (for flushing loos). All those things are cheap at the time of construction but prohibitive afterwards.

Raked out courses and separate pointing is the standard all over here, always wondered why it's done in one go in the UK.

Digging a hole (kruipruimte) almost down to water table is not helpful either.

Of course the building will get pointed by a color of choice. Pointing one house like this will take 2-3 days. The cavities in the brick work is to let the space between exterior wall and interior wall breathe. There is no contact between the two walls. There's about 10cm (or more) PIR insulation and an air cavity of a couple of cm's between the two. The black plastics will be taken out once the pointing is done. This is just to make sure the holes don't get filled with mortar. These are houses, not apartments. There's a water barrier in the brickwork and also underneath the complete concrete slab. The screed you are talking about is not screed but the concrete slab/foundations on which they put piping and electricity. Screed will be put on afterwards, then a final floor. 90% of the houses have concrete (first and second) floors since the sixties. Cheers from... Belgium!

Insulation is a different matter and typically the south worries less about thermal insulation albeit they should worry a bit more as it is warranted. Thank you for posting another interesting video

Nice idea re the manifolds for the domestic water supply (both hot and cold). I did some work (chlorination) at a fast food restaurant in New Brighton, the Wirral, around 5 years ago. The plumber told me the manifold was so all the pipes could be run in plastic to each area, so if there was a leak in one area, the water could be isolated at the manifold and then repaired or replaced. This also minimised the amount of joints needed in each area, joints which invariably end up causing leaks. The manifolds for the domestic hot and cold water supplies were located in an accessible cupboard near the incoming water main.

Britain used to lead the world in so many things. Have to say I'd be much happier paying for and living in a house built to these Belgian standards than our piiful excuses for a home. Well thought through and cost-effective, with a good dose of future-proofing. What's not to like? Thanks for shining a light on this.

I added DPC to a home aged over 120yrs . I added the DPC in sections of five feet each day at various locations of the home . Two days after adding a section water would run from the wall onto the floor. I would have to wipe it up every day . When you stop the walls sucking up the water it falls resulting in puddles. It's a wonderful sight to see .

It's worth remembering that damp also will track along horizontally... from a neighbouring wall 🧱 or yard wall etc. Into a wall that has a " rising " dampproof membrane below it. Another thing is many times rising damp is confused with condensing moisture from a warm atmosphere onto a cold North facing wall , especially in cupboards or units

The porotherm blocks have a capacity to carry between 10 and 20 Newton. So yes, you can just lay a concrete floor on top of them. These blocks are produced in Belgium. Putting that local clay to good use. These blocks also allow for 100% machine produced prefab walls. Produced on monday, loaded on tuesday, arrive for installation on the building site on wednesday. Takes about a day to install 1 floor (of your average house) They are prefab produced incl damp proofing, dooropenings, windowsopenings, isolating block in the bottom row, etc...

@@hoWa3920 Belgium has a big self-build culture, so quality is driven by a huge choice of materials from all over Europe, high training standards and smaller family builders. The basements and lofts that come as standard in Belgium, need adopting in the UK, but UK is the opposite, dominated by greedy cheap corporates and unskilled workers.

As someone with years of experience designing buildings like this on the continent, and quite a bit knowledge with water proofing these type of particular, I can confirm that extra bit of DPC hanging over there is a cover protecting the door where the mice can get in and out.

Thanks Roger, always interesting to see how our continental neighbours differ from our techniques, I've always liked those Porotherm blocks, lighter to handle than concrete blocks for sure, and quicker to set too ! Pipe in pipe seems like a great idea !

Ah, in the UK you got a Roger too? Nice.

My brother lives in Aubange and in a newly built property and i have to say credit to Thomas Piron in the sense the way they build properties unlike UK builders trying to cut cost in every single way and step of the build. No snags, house is energy efficient and triple glaze, external roller shutters/blinds to name a few. And bear in mind, im talking something that was built 10yrs ago!

Belgium houses had wooden roller shutters going back to at least WW2 ! Now PVC of course. Windows opening inwards and large strong doors with no bottom brace.

Thanks Roger! Very interesting. I think a lot of people could be interested in a detailed comparison of building techniques between different countries. In Europe it seems to be big differences. Partly due to national traditions and partly due to the circumstances. Here in Northern Sweden the cold is dictating a lot of things and demands a lot of the building resources. Many new houses are built on concrete slabs on top of eps insulation and a layer of macadam gravel. Only some factory produced module houses are built with crawl spaces. Crawl space is cheaper but moisture problems are extensive, problably due to cold ground under the houses causing condensation in the summer. So the building techniques have evolved and I think that they will continue to evolve since modern living standards with central heating and inside plumbing have not existed for that long. For many people only about 70 years, And that is only 2 generations to evaluate the building techniques if you consider that it takes 30 to 50 years to really know what is working well and what the advantages and drawbacks are. I am now working with replacing septic systems in the countryside, some you could say are 1st generation and some are 2nd generation. And from what we know now, and the procedure that we follow when selecting new systems, it is very clear why some of the older systems do not work anymore, and some stopped working very early on.

I live in Belgium. Not a professional builder but did build my own house. The slab you see over the foundation is a slab that runs through to the inner wall with a step-up. So moist and water is deviated towards the outside and not towards inside. Many things you name was logic to me, the way it should be done. Like pipe-in-pipe is very Common here

The pipe-in-a-pipe idea got me, that's the first time I've ever heard of the concept (and so inexpensive?). Here in Australia we have high construction standards with ventilation to the cavity via terracotta bricks that are double the height of a regular brick about the same length each with 15 square holes in it: but that lets insects into the cavity which can be stopped by buying industrial size "scotch-bright pot scourers" from the larger hardware stores cleaning sections, the industrial size allows essentially identical airflow but totally obstructs cockroaches and other bugs. This is a great channel definitely worth a tick and subscribe :)

District hearing is basically piping hot water coming to your house and you have heat exhanger in your home to reduce it to hot water and forvthe radiators. Charged by volume and temperature delta over your heat exhange(used kWh). Plus monthly basic fee to cover the upkeep of the district heat grid.

It's actually not even luke warm (waste) water which is used by the heatpump to condense into Hot water. I don't mean sewage water but water from industrial processes etc which produce excessive heat.

In Belgium and the Netherlands as well, the briscks are lais and at the end of the day they are scraped out. At the end, a specific separate craftsman sill do all the poinying in one go with a sepate mix, which can be adjusted in hardness, colour, depth etc. It's ver important not to have the pointing too hard or the bricks will freeze to pieces. If the pointing ever goes bad it can be more easily replaced as well, without damaging the bricks. The mortar is meant for building, the pointing for protection.

Many bricks are actually reused from former buildings, as they have Factories cleaning used bricks in Belgium! We of course also use moisture protection in the walls in low, Denmark. When walking in Belgium years ago, I liked looking at the solutions used in Belgian houses, also a single and tall, "Town House" with flat walls on both sides. standing in a Belgian field!!

In Germany, we used a wet cement-like dpc that we put on with a trowel. the 1980s

Some ways to get ground water out of your old building : sometimes ive seen in Belgium : every foot they drill a horizontal hole into the walls a bit above ground level and inject some kind of fluid , that creates a water repelling barrier . Another way but more costly :. Piece by piece they dig some stones at or even below ground level and underbild. It with a concrete layer + a moist screen . 3: I used to live in an old cottage , end of 18 century . Hardly no foundation , floor tiles one sand floor . The entrance silt was only half an inch high , and the street side of the house was actually a foot under street level ! One time there was a severe rain and flood warning . So I picked up some sandbags at the town fire department to be shure . I never got flooded . Maybe the only thing my landlord did good for the house , was to Fill the whole backyard up with stone building rubbish .so the whole garden collected the rain up very quickly … I discovered it because at some places in the garden the grass grew very little ..

The pre insulated pipe cannot be altered/replaced once installed, we usually buy it dual red/blue on 50 or 100 m roll in DYI. Still pretty handy though. The non insulated version is indeed two separate pipes but it would be very hard to replace if there are curbs and bents. I think it is there to protect the actual waterpipe from chemicals and frictions when it expands and retracts due to hot and cold water

I have a house in France that has copper pipe in plastic tube similar to what you are showing here. It is buried in a concrete screed over the floor similar (I think) that will happen in this house in Belgium. The copper pipe is impossible to replace without digging up the floor! Also since the evidence of a leak only shows at the end of the outer tubing, you have no idea where the actual leak occurs and where to start digging. In general I think that not sufficient consideration is given to future maintenance requirements, access etc. It's cheaper just to bury everything.

The pipework in this video is plastic in plastic, so possible to drag through (might need to pre-lube the outer pipe though). Obviously rigid copper can't be pulled out of a buried plastic sleeve. Perhaps copper in plastic is to offer a small amount of protection from rough treatment during construction.

Hi, Thanks for your interest in my comment. However while there is some plastic pipe used I think there is a lot of copper. Also if it were plastic in plastic you would never pull it through the tortuous bendy routes that they have used even if it was lubricated. Look at the following; 1:56 you can just see the copper appearing out of the outer red tube, also there seems to be some brazing on the red pipe, much favoured on the continent where they do not use flow solder joints (how this coexists with the adjacent white piece of plastic I do not know); 2:26 look at the bends you could never pull plastic through these, pre-lubed or not, also on the left hand side going up the wall there is uncovered copper: 3:26 here you can see some plastic pipe, pretty stiff not for pulling through any of the routes I refer to earlier; 6:46 look at the bend on the yellow pipe, I think copper with a taped covering. I have always thought that the use of an outer tubing or tape is to protect the copper from the covering concrete/mortar as a corrosion preventer, they do not co-exist well with each other. Also on the underfloor heating which is plastic there is no outer tube (normal) and is buried directly in the concrete screed. No corrosion problems but a repair nightmare!@@stephen-boddy

@@John-dp8ohDo a Google image search for "pex pip blansol" you will see pipe-in-pipe where the inner "red" is distinctly copper coloured. It looks an exact match for this stuff. The white bit looks like something similar to a sharkbite or push-fit fitting, although I don't recognise the exact brand. As to the ability to pull through? Have you tried it? To quote the Blansol manufacturer website: "Besides, the corrugated duct allows an easy substitution of the pipe if needed. Thanks to the use of corrugated pipes you will just take out the damaged pipe by pulling it out and introduce a new pipe with no need of major work." You mention the copper going up the wall. The pipe-in-pipe is for pipe that runs under a screed. They wouldn't need the ability to pull through on a pipe that isn't encased in concrete. That length of copper looks like it's a feed between two parts of a manifold system - one half feeding the cold supplies downstairs, the other feeding cold supplies upstairs, and the copper linking them. For the UFH, yeah, that stuff pops and you're in a world of hurt. It can't use pip, or you'll be waiting twice as long for a warm floor. The yellow pipe is completely different. Here in the UK that is for mains gas, and I'm pretty sure that is an internationally used colour coding, and that you must also use copper for gas (at least in the UK), not pex. So no, that one is not pipe-in-pipe, nor is it easily replaceable.

@@John-dp8oh the pipes used here in Belgium are called multi layered pipe and indeed contain both metal and plastic, replacing them is not easy and the outer tubing is more for insulation or expansion and contraction purposes. these pipes will never fail if placed correctly, any leaks will always present at couplings, wich should always remain accessible and in the floor only straight, uninterrupted runs should be used.

If you are interested in rising damp, come to Central and northern Portugal. It rains more than in the UK, that rain happens in half a year and many houses have no dpc or damp prevention of any kind. Concrete floors were often poured straight on gravel on soil. Traditionally, downstairs was for storage and the family lived upstairs.

We keep being told about Portugese damp so maybe I will take a look.

I've built in the Netherlands and Germany too. Damp proofing is critical in these places. As are details to shed water from the cavity.

Very interesting, thanks for sharing. I built a house with my dad in RSA, and was very surprised at the lack of effort put into UK housing when I came here. They seem to be built to function without anything not required by regulations added. I'm talking about the general housing, I'm sure the more expensive properties have better fittings, etc.

We really are backward in most general building techniques compared to Europe. When working in Germany in the mid-1980's I would marvel at the fit and finish of the local buildings and their plumbing, electrics and even carpeting and skirtings - if you know, you know.

Fantastic video. Ideal for all those American KZread videos about how easy it is to run extra network or HDMI cables in walls, not in Belgium. Our houses are made of stone and not plasterboard.

thats brilliant pipe in pipe easy fix

That pipe in pipe plumbing is a lovely idea

I learnt my trades in France, when I returned to the UK I was shocked at how antiquated our buildings systems were - the victorians knew more about damp avoidance than we currently do, and architecturally we rarely have anything of 'merit'. We are a country focused on low cost rather than quality.

Very nice build, should be done always and everywhere.

In South Africa all floors and stairs are done with concrete, they use scaffolding forms to lay the concrete over the scaffolding forms to lay the floors. Much better construction for sound proofing, they even use that in duplex construction, not just flats.

Same in Belgium, but we lay premade concrete slabs first, and top that off with a concrete poor.

Mother’s house had flat backed ogee cast iron gutters. Horrible things that rotted at the back. Plastic went up in 1970s. It’s still there.

In Naples I saw walls made from 'tufo' a volcanic rock. I'm told it is lightweight with great thermal properties. Trouble is, if you don't render it, the weather erodes it. I saw a lot of crumbly walls there.

We really need to learn new stuff like this in uk. And train builders better

Poland, for as long as I remember (50 years), walls are separated from foundation with a layer of thick tar paper, brushed with molten asphalt/bitumen/tar. I have never experienced any dampness in the buildings or seen any water deterioration.

The way you should build with these blocks is to install a concrete ring beam at the top course before you put the precast floor slabs, if the blocks are not structural - numerous benefits

as a belgian loss adjuster for insurance companies: yes rising damp very much exists in belgium. it's one of the big exclusions of insurance policies so we're always checking if the cause of the water damage is rising damp in order to deny damage claims... older buildings or add-ons against old existing garden walls don't have the damp foil in them, they always cause trouble with rising damp.

Fixing windows with cleats is quite common in the commercial window industry in the UK due to wind loadings

Nice description and there is actually even more layers underground. Unfortunately good builders are needed in combination with good techniques and we still see a lot of failures in new builds. Just one info about the tablets under the windows these are made of Belgian bluestone - Pierre blue du Hainaut a product we Belgians are very proud about and a stone you will find in a lot of heritage buildings also used for flooring, kitchen tops, bathrooms.

Fascinating how others do it , we could all learn and improve our own building practices to reduce waste ,time and increase efficiency and liveability

hi Roger the we have some great systems we can use the only reason we do not is cost simple as that the big builders lead the way and profit is king when we build we build like this ref ( bi -fold doors ) and membrane always will but look at new builds cheap shoddy in general mate , great vlog mate keep it up

The best solution for rising damp is ventilation under the flooring so plenty of air bricks allowing the air to circulate and keeping the brickwork dry under the floor. What I have found with most properties that are struggling with damp is lack of ventilation or blocked vents due to driveways going in and covering the vents and not being 6inch 150mm below damp proofing to prevent splash back, then you have broken drains leaking water under the house or even leaking gutters dripping rain water and not draining off.

In Belgium we start with a foil on the ground before we start building. Then you have the layer between the bricks (above ground level) and the first layer above ground is an insulation block. New houses never should have problems with moist when build properly. It is up to the architect to guard proper installation as he will be held responsible for 10 years.

Fascinating video!...interesting to see how things are done on the Continent. My Victorian ancestor was a property developer from Brussels, and settled in South London. The brickwork is stunning...I'm guessing that pattern of bricklaying is Flemish Bond?

Walls are cheaper than windows hence the push for "mews" houses in the UK with tiny windows, which I agree is a great shame. I live in a 30s semi because they (in my opinion) got the layout right and the proportions of windows right too.

Homebuilders spending a bit more to do things properly? LOL. That'll never fly in the UK.

I think we can all learn from looking at Best Practice in different countries. It would be great if there was a system to look at and recommend changes based on efficacy and cost.
