________________________________________
Building techniques reflect the practices, materials, and methods employed in the construction of buildings.
These techniques vary significantly across countries due to climate, available resources, cultural influences, and technological advancements.
Construction Materials
Belgium's construction materials have historically included brick and stone, similar to the UK. However, the use of local natural stone is more prevalent in Belgium, especially in regions with rich stone quarries. In recent years, Belgium has seen a significant rise in the use of glass and steel, particularly in urban areas, facilitating the design of buildings with more natural light and innovative forms.
Construction Methods
In Belgium, traditional masonry remains a standard construction method, strongly emphasising craftsmanship and detail. However, Belgium is also at the forefront of adopting passive house standards, which require highly efficient construction methods that minimize thermal bridges, ensure airtightness, and incorporate super-insulation to reduce energy consumption.
Architectural Styles and Influences
The architectural styles in the UK are diverse, ranging from the medieval Gothic to the modernist and contemporary. British building techniques have adapted to accommodate these varied styles, focusing on preserving the historical character of buildings while integrating modern amenities and efficiency standards.
Belgium boasts a rich architectural tapestry that includes Romanesque, Gothic, Baroque, Art Nouveau, and Modernist styles. Belgian building techniques have evolved to support this diversity, with a particular emphasis on integrating modern construction technologies without compromising their architecture's aesthetic and historical integrity.
Innovations in Sustainable Building
The UK is actively exploring innovative building techniques that promote sustainability, such as green roofs, living walls, and sustainable materials like bamboo and recycled plastics. These techniques aim to reduce buildings' environmental impact, enhance energy efficiency, and support biodiversity in urban areas.
Similarly, Belgium is pioneering sustainable building techniques focusing on energy efficiency, renewable energy integration, and water management. Innovations include using phase change materials for temperature regulation, rainwater harvesting systems, and geothermal heating and cooling systems, reflecting a commitment to building in harmony with the environment.
While there are similarities in the building techniques used in Belgium and the UK, reflecting shared European architectural traditions and challenges, the differences underscore each country's unique response to its specific environmental, cultural, and technological contexts.
From the materials they favour to the construction methods they employ and their innovative approaches to sustainability, these differences highlight the dynamic and evolving nature of the construction industry in both countries, driven by a continuous quest for efficiency, durability, and harmony with the natural and built environment.

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.

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.

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.

We, the Dutch, take our hats off to the Belgian builders. I think it has to do with their urge to build their own home. Not renting it. Every time I visit Belgium, I'm amazed by the level of finish. A trick: a few years back, a company built an annexe to our house. I bought a teachers' blackboard ruler (the large white/red ones) from the internet and every evening when the builders went home, I took tons of pics of their work: the plumbing, electrics etc with the ruler next to it and a reference point that would still be visible when the floor and walls would be finished. In a way: mapping out the routing.

@upnorthandpersonal 2 месяца назад

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.

Wood is a very poor conductor of heat , the heat you generate remains in the home . Put your arm to a concrete wall, it's cold . It will remove the heat from your body until it heats the entire wall , which can not happen. Put your arm to a wooden wall , it is instantly hot . It doesn't take any heat from the body, it can conduct it .

@richardharvey1732 2 месяца назад

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.

Lots of things are done a bit different here on the continent, but strangely enough the Poroton blocks also didn't take off in the Netherlands, instead like the UK aerated concrete is mostly used for the inner leaf. Dutch houses in general have more details in common with the UK than in other continental countries. But we do the damp courses and pipe in pipe/wire in pipe like in Belgium and others. Raked out courses and separate pointing is the standard all over here, always wondered why it's done in one go in the UK. The building you are in isn't a flat, it's a 2 story house, at 6:00 you can see the opening for stairs in the ceiling, concrete first story floors is standard here, timber isn't used anymore for floors because concrete offers better fire safety. Older houses pre 1960 often do have timber floors still. Mine from 1932 does.

The blocks are actually only used in small projects. If they do a series of (connected) homes the inner walls will be concrete. For me the amazing part is the city heat pipe running over the ground floor to the distribution point inside the house. Guess that must mean that it is a low temp system. In The Netherlands you will usually see these pipes running through the crawl space underneath the floor, carrying temperatures exceeding 70⁰C.

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.

@gurglejug627 Месяц назад

'A battery' - you need loads of batteries to come anywhere near having the electrical capacity to run a 'normal' household. Less where you are of course in France than in many places, but remember that no matter how good your charging system and inverter, they will degrade. I do think water heating solar panels should be standard (or at least the house built for an easy retro fit at any point) as well as a double-coil heat exchange boiler: The issue is probably possible liability for Legionnaire's disease.

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.

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!

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.

I've been lucky to visit the area for work a few times and have hired a bike for some exploring in my spare time, and no matter where you go you'll see it. I don't know if I'm just luckily always in premium areas or if they just generally have better design.

@louis-philippearnhem6959 Месяц назад

Belgians are "born with a brick in the stomach". The saying "een baksteen in de maag hebben" is often used in a humorous way, but it also reflects the deep-seated desire of many Belgians to own their own home. Greetings from Leuven!

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 .

@mikapeltokorpi7671 Месяц назад

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.

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.

@stephen-boddy 2 месяца назад

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.

@John-dp8oh Месяц назад

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

@stephen-boddy Месяц назад

@@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.

@joris188 Месяц назад

@@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.

@larion3296 2 месяца назад

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.

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.

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.

@alanyoung7532 Месяц назад

Very interesting video. Always useful to consider practices in other countries as this is a good way to learn from one another. The pipe in pipe appears to be a win win situation. Having a raised floor level is also highly desirable as this both prevents rain splash-back striking the wall above DPC level and also allows any damp that is rising to be able to freely evaporate sideways at low level. Disabled access can and is accommodated by designing in ramps, mini-bridges and other forms of appropriate landscaping, which just needs a touch of imagination and a good designer. I cant recall anyone suggesting that new buildings should not be provided with DPC'S myself as such buildings by design incorporate barriers to moisture (eg cavities, DPCs, cavity trays, sealants etc). The debate about rising damp and the go-to fix of injecting chemical damp-proof courses and applying brittle cement rich impermeable renders revolve around old lime based solid walls- water always takes the line of least resistance and will therefore evaporate sideways, rather than rise, if it can freely do so. I do not wish to rule out the option of introducing a retrospective DPC in older walls but this must be one which will provide the required degree of long-term protection and any remedy should of course follow a reliable diagnosis - damp is a symptom. Always wise to keep an open mind when investigating building defects of course.

Proud of myself. I have already done pipe in pipe of my own back, only one radiator tho. I was running 15mm in short wall channels from just below skirtings to a couple of inch up behind radiator to then feed 10mm plastic through to valves, to get a floating radiator as I call them. But on the living room I decided to run from under stairs all way way to other side and up two cannels to back of radiator, insulated the 15mm, then put the floor down. When it was time I just pushed 10mm from rad until it popped out under the stairs to connect. Idea is if I get a problem the the plastic pipe I can just feed a new length thru without taking up the floor. I am planning to run cold to and hot from the boiler the same way, under concrete when I do the kitchen floor, 22mm plastic so I can feed 15 mm plastic through and again easily swap out if I have any probs down the line.

@gavster89 Месяц назад

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 ..

@johnny71c 2 месяца назад

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.

@ronnysocquet3297 9 дней назад

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.
