In this video we bring you lots of progress from our extension build. We start of with laying the block and beam, showing you cutting concrete beams using a Hilti dsh 600x petrol saw, and then putting the infill blocks between beams and the slip bricks around the perimeter. There is more timelapse bricklaying from Alex as the walls are brought up to block level, and later Alex will fill wall cavity with 5 in 1 concrete mix so he can then get on with laying the ytong 7n blocks internally. John's main job is doing the groundworks which involves new drainage installation and he shows you how to move a manhole. Tony and John excavate with the Yanmar vio17 and break up concrete with the Bosch GSH27vc and Joe gets involved with his new ox pro mini round point shovel. The guys dig out creating a new manhole and lay new sewer pipe connecting plastic soil pipe to clay using a flexseal AC4000 connector with the new drain connection in place, John makes a temporary inspection chamber cover and all pipes are covered in pea gravel. lastly John has the job of digging concrete footing and adding a few rebar to form a concrete pad for the lintel over the pipework. Joe is mixing concrete for the footing and for John to flaunch pipes.
PLEASE NOTE: we’ll endeavour to answer questions and comments as soon as possible depending on our work schedules.

Installing an Underground Drainage and Inspection Chamber | Single Storey Extension #11
When you see a site that clean and tidy you know you have a quality builder. Absolutely bang on guys 👏👏
Hi denty32 much appreciated it’s the only way all the best Tony 👍
People just dont realise how much hard work goes into ground works .so much skilled hard work gets covered over never to be thought of again.
Glad you showed and a cracking job of it brilliant lads .
Justin Brickright 👍
Thank you for the kind words Justin, have an awesome week bud! 👍
Absolute pleasure to see videos like this, guys who know exactly what they're doing and doing everything properly, thankyou and continue the great service!
Thanks for watching, have an awesome week! 👍
First time on this channel and loved how you go to great length to explain some of the details, rational behind it, tricks of trade and of course building reg. Really supportive team and safe work environment you have there, as safe as construction can be! Thanks for sharing and all the best
Hi thanks for your kind words have a awesome week all the best Tony 👍
These men work as a team and are very, very employable. Fantastic work ethic and knowledge. This video says everything you need to know about this company.
Love seeing tony getting stuck in with all the lads. True boss!
Thanks for watching Andy! Have a lovely weekend 👍
Speaking as someone who has been a victim of the 'cowboy' builders these videos are a pleasure to watch.Fantastic professional work.!
Hi Andy much appreciated sorry about you experience hopefully one day this will never happen all the best Tony 👍
Have worked in the building trade all my life, now well retired at 82 but just love to watch your videos and work ethics, does the building inspector prefer not to appear in your videos. I can only think you have a good relationship with him, unlike many that I have met !!! Keep up the good work guys.
Epic. Love having a longer video 👌🏼🏴👍🏼
Thanks dude! Have an awesome week 👍
Best building channel on TH-cam I reckon and there’s some stiff competition. Loving the longer videos and meticulous as always lads!
Thanks for the kind words Ricki, have a great week! 👍
Those small shovels are great for sand castles at the beach 🏖. Especially digging the the moat. 😁
😂
@@BuildWithAE tried and tested, promise
You and your team do a very good job, some of the neatest groundwork’s and foundations I have seen, great series look forward to the next few videos up to roof level!
Hi Dan much appreciated glad you are enjoying the videos all the best Tony 👍
My bf saw your van outside a house in Virgina waters he's working on the went worth estate
Good to see progress on this one!
Great video Guys really appreciated the new inspection chamber install details. I'm about to knock an old one out and install new. Great heads up on that. Buying the correct fittings etc is just as difficult when you're a newbie to it. Great work you lads do.👍👍
Lovely work gents also a fan of the longer day by day log of the progress, keep up the good work.
Thanks for watching James 👍
Customer should get that lead water mains pipe changed at the same time.
sweet video ! makes you really appreciate all the thought and effort that goes into getting the groundwork right
Hi A&E, I own a small building company covering similar work to you but on a smaller scale. I have learnt so much watching your videos and you are as good at teaching as you are building. Keep up the good work and keep the videos coming. Stuart @ DPS Building Ltd.
Awesome job as always. I would recommend to the client to replace the water main for a bigger one 32mm which would improve flow, good opportunity to do it while you’ve got everything dug up.
Excellent craftsmanship all round
Nice work guys! Really coming along quickly now. Lucky with that water pipe when you were digging the trench for the inspection chamber.+++👍👍
Excellent.. professionals at work
Thank you!! 👍
Smashing it again ! Tony , next block n beam have a look into the polystyrene blocks . We’ve worked on a load of them , less weight , quicker no dust or noise when cutting and above all warmer 👌🏼🧱👍🏼
Hi Guys I keep toying with the idea but how stable are they underfoot last time I found them a nightmare 😂 I should give them a whirl again all the best Tony 👍
@@BuildWithAE just a bit a common sense really . ( don’t walk in the middle of the beams ) but youve got a great bunch lads there . We have it in our new build and it’s definitely warmer .
The speed it goes in plus no petrol saw , noise , no grouting . You end up with about 300 mil of insulation too . Not sure about cost difference but you it definitely save in labour 🧱👍🏽😁
what a great video! Thanks!
So much work 2 get out of the ground. Excellent stuff n look 4ward 2 the next vid.
👍😎
General rule is that a 3rd of the cost of a project is in the ground, obviously this doesn't apply if your fitting lavish bathroom suites and handmade kitchen etc. but gives a rough idea to the amount of work. And think most of the work will never be seen.
Amazing progress!! Looking forward to seeing the next video in the series
Loving the longer videos
Well explained and great thought process. You guys do a great job 👏🏽 👍🏼
Cracking work guys.
Thanks for watching Jeff! Have an awesome week 👍
Loved that! Just so much information 🤯🤯🤯❤️
Loving your work lads. Coming on nicely 👌
Loving all your vids guys. I'll soon be ready to start my kitchen extension and I've learned a lot.
Many thanks.
Hope the extension goes well for you Darren! Take care 👍
Awesome job as usual 🏴
Thanks Yorwerth, have a great week! 👍
I worked in a Mercedes body shop in the 90s and saw an instant decline in quality when Mercedes linked up with Chrysler . The Germans were persuaded to run the presses stamping out the panels much longer before they were re- profiled hence all the corrosion on the edges of the panels and an example I saw on the later facelifted E class 124 models was instead of 5 clips holding on the chrome bumper hockey stick they only fitted 3 clips so 5 pins on the trim but only 3 clips fitted to save money . That was the mind set in a nutshell . Hopefully Alfa will not fall into the trap of taking all the bad ideas from Stelantis ( France let's be honest )
And I would say no French company is going to have a Frenchman stood around with his hands in his pocket while an Italian is working and earning so if anyone is for the chop it will not be Frenchman.
Keep up the good work Jack
Best video yet!
Pardon my ignorance but why do you run the block and beam at an angle rather than parallel with the walls existing build etc? Many thanks, great quality work btw
Great bit of work lads technical bit of groundwork bet your glad to be out the ground
Thanks Steve,
It definitely was a momentous occasion!
All the best, John 👷🏼♂️
Not just any old groundwork, ......but Build With A&E groundwork.
Fantastic as usual, would love to work with you guys..... I may be a little too sweary for the channel though 😂😂
Haha thanks for watching Alan! Have an awesome week! 👍
I had zero faith in builders after being scammed and ripped off on numerous occasions, BUT, you guys have restored my faith. If only Carlsberg made builders #truepros
Great video once again boys 👌👍
Great video 🤜🏽🤛🏽 excellent info but no cooked breakfast on a Friday 🙀
Easily 50% of the job up to damp on this one. Must be a relief to get onto the superstructure
'Build with A&E boot gaiters available in the merch store now'👍
😂😂😂 I think your on to something there!
All the best, John 👷🏼♂️
@@BuildWithAE Top man John😎
Didn’t they want a new water main to get rid of what looked like a lead main while you
had it dug up.?
Hi r b,
The clients have had a new main installed since the filming of this video. It was planned to be replaced, but we had to wait for the fitter.
Hope this helps
All the best, John 👷🏼♂️
Awesome guys 🤩
Great workmanship again.
I do a lot of ground works and where we are in Suffolk you have to have 150mm clear cavity below the pot and beam floor this is a nhbc and building inspector requirement.
Mite be different where you are.
Keep up the videos.
Interesting! Thanks for watching Trevor, have an awesome week 👍
Great stuff as always lads 👌
Don't know anything about building in the UK but, in the US we would have put plastic sheeting under the floor with a little pea gravel to hold it down, to stop the damp. Really we would have poured concrete footings and maybe the whole floor
Nit picking here but the cavity fill should be sloped to the outer leaf 25:30. PS you love your slow mo shots of pea gravel 😂
Really enjoyable to watch and learn. Is it a really odd shaped plot? As they extension is off at an odd angle.
Just wondering why kitchen soil stack in middle of the floor didn’t go straight out to the path onto another i.c to avoid all those bends and make rodding easier
Hi Ron no worries on ridding, it so everything can be hidden all the best Tony 👍
thats a lot of work guys, well done
Is it okay to have those bends in the waste under the blocks? I thought that wouldn’t be allowed
didnt think you was allowed 90 degree bends on a soil pipe for change of direction?
A sewer riser under the kitchen sink? Is that right?
How much would a project like this cost
Arent you supposed to have an inspection chamber at any change of direction?
Another quality video I always avoid jobs with drainage how do you price for that work is that and extra on top of the build price
Don't mean to have a dig I enjoy watching these videos well done to the A & E lads but when you layed the concrete pad the steel should have been dowelled into the existing found or Masonry not the clay soil, if that was me I would have toed the lintle into the existing house so that pad found wouldn't have been needed,
Also your cavity fill in the cavity should be 150 minimum below the block and beam floor on this type of system not dpc, you treat the beam in the same way as a timber joist as the block and beam will suck in moisture, on foundations that deep normally a clay board would be fitted internally to the foundation wall for any clay expansion property's
Do enjoy watching your video content makes me want my own channel keep up the good work lads 👍
Great video guys and great work as always. Really good watch. Guys at what ratio do you install your underground pipes seems to vary so much. Some lay 1:40 some 1:80 or even more 🤷🏼♂️. Thank you in advance for the advice. 👍🏽
Hi Martin 1:40 to 1:60 depending on connecting pipes and qty of toilets all the best Tony 👍
Is doubling up the beams on the longer sections standard practice? At what length would you do this? Are the 150mm beams?
The beam company drawings all the best Tony 👍
What happens at the door threshold between the outer skin and the inner block and beam? Filled with concrete or would that bridge damp course?
Looks less than 150mm min void area mate
Love your videos. Question: why don’t you just pour a full concrete pad vs this block system?
Hi Mr.Flippy it’s more cost effective and a quicker process all the best Tony 👍
@@BuildWithAE ok thanks. Great work.
Have you ever come across this. I've been told it's a land drain. I can't add pic but they are clay pieces about 12 inches long and in a n shape just placed underground to divert water and it has flooded my oversite area where I changed the main sewer pipe and the ground in parts is really spongy. I've put blue pipe in for now but don't know how to stop or divert this land drain and I can't continue with my slab because even with 2 inch of type 1 wacked in there for now it's still moving under foot. Any ideas. Thanks
You sir and your team are effing legends! so enthusing to hear a contractor on site actually knowing what they're talking about! That's normally the structural engineer with degrees up to his butt cheeks. Excellent work guys, please take on apprentices and educate them the proper way. Major props to all of your squad!!!!
Thanks for watching the video buddy! Have an awesome week 👍
No goggles while using a grinder?
Great video but correct me if I'm wrong? I thought it was illegal to run rain water from gutters into waste water system. They should run into the stormwater system or a soakaway.
Hi Rob,
The existing drainage is a combination system, so perfectly fine to do what we're doing. We are also running around half of the roof runoff into a soak away, which was shown earlier in the series.
Hope this helps.
All the best, John 👷🏼♂️
@@BuildWithAE Thanks for your reply. Yes you're right I just found out that's fine if the house was built before 1970.
The new gully you fitted at point 18.25 on the video is that going to take rainwater off the roof as I thought rainwater and foul water had to be separated for building regs. Also it appears you layed some of the beams side by side and infilled the gap with concrete, why was this?
Hi Kevin,
In older properties they are dual lines not separate as of today.
Beams are side by side as Beam details required by beam company then gap filled all the best Tony 👍
@@BuildWithAE Keep up the good work you'll soon be on the 1st fix.
@@BuildWithAE what? dual? separate? youre putting rainwater in with sewage?
@@DICEGEORGE Puzzles me to mate
Great video as always. Question from an "enthusiastic" diy-er. Is there a reason for the gully at the bottom of the drainpipe? You went to the trouble of digging it all up so my simple mind thought the drainpipe could connect directly to the inspection chamber. Building regs maybe, or perhaps you wanted to keep the original drainpipe work?
I'm not 100% sure this is correct but i think it is due to there being an outside tap there so it would give excess water somewhere to go. There are also other good reasons to put gully traps in, the main one being that it stops a bunch of debris that comes of the roof blocking the pipe but also provides a nice water seal trap to stop the sewer venting nasty smells straight on to "leaky" gutter down spouts which do not have rubber seals.
@@Palo-jm7xc Thanks for the reply. All makes perfect sense now you have explained it. 👍👍👍
Love these longer videos guys! Any reason why the block/beam was installed at that angle? Cheers!
Most likely to get a beam tight up with the existing building, makes things a bit easier.
Hi David,
The floor was designed to run parallel with the existing building for ease of installation. It meant that we didn't have to make pockets in the back wall of the house, saving time on additional work.
Hope this helps.
All the best, John 👷🏼♂️
@@BuildWithAE Cheers John , thanks for taking the time to reply. Love the viseos!
@@stanevans9334 Cheers Stan, that makes sense. I think sometimes the camera angle made the angle of the beams look odd (not parallel). Or it could be my eyes! Appreciate your reply.
@@davidtaylor4975 - I think you've accidentally invented a better word for videos there, David.
I noticed in some of your other videos you backfill solid drain pipe with pea gravel where it’s not located near your drainage chamber. Seems like a waist not to just use that fill especially when I see you guys purchasing that aggregate by the cubic yard bag.
Where do you get your inspection chambers? Are they HDPE?
Online mate
Why u don't change the main its free
Why lay the block & beam at that 20-ish degree angle to the back wall? Seems like that created more work?
The floor was designed to be layed parallel with the existing house, as this meant we didn't have to carry out additional work creating pockets in the back wall to carry the beams.
I hope this helps.
All the best, John 👷🏼♂️
Ahh, okay; That makes sense, I guess; I was thinking as there didn't appear to be much cutting of the beams around the new wall, that you'd just leave the beams slightly short where it'd meet the existing building
@@thisismissem - the beams have to be designed and made each as one piece, not to be cut. The tension in the steel reinforcing bars has to be formed so as to loop backwards at the ends for strength of hold. You should get all beams at exact length with no cutting, as the hold of the rebar - and the tensile strength - would be compromised if you cut the return off.
Some say pea gravel to the crown of the pipe and others like yourself just throw it in who’s correct ?
Think its down to the building inspector, I seem to recall graded backfill is ok, but not 1/2 bricks/ lumps of concrete.
Just wana to ask you why have you gone for block and beam instead of your usual concrete work
The block and beam floor was specked, so that's what we installed.
Hope this helps.
All the best, John 👷🏼♂️
@@BuildWithAE
You could maybe do a video about this foundation vs your normal concrete work
I think it be interesting to know the cons and pro vs the two
If you can
Hi does the old soil pipe from the upstairs stay in and get boxed in.? Thanks great content
The soil pipe will be moved inside to a more discreet place, it's just there for a temporary solution.
Hope this helps.
All the best, John 👷🏼♂️
@@BuildWithAE Thanks John. Can you show us when you move it. Cheers
@@Oncewasdonka - we'll be waiting with bated breath for the moving of the soil pipe ! 😉
Any tips on finding good builders like yourselves?
Hi megaman2016 I would recommend using the FMB on line great way to source a good builder
All the best Tony 👍
@@BuildWithAE builders like you are worth every penny but unfortunately there are far too many cowboys and it's hard to know what type you are hiring until the job has started! Many thanks for the tip
One thing about UK building practices. Not easy to change your mind partway through. Things are literally "set in stone" as you go. Better have all the plans sorted before you begin. "We'll figure that part out later" really isn't something you can do,
👍🏾
👍
That burnt off the old fry up.........
Haha, thanks for watching Glen! 👍
Not enough tea and too much working. Sort it out lads.
Better way to keep your foot dry is put your foot in plastic sacks and tap the tops to your legs and it keeps tour boots dry as well
I can’t believe a building inspector would pass that with all those changes in direction.
Should of come straight out of the building with both lines and extended the main line up the side of the house to an inspection chamber in line with the farthest drain.
Thumbs down from me
