Basement Tanking, Windows and External Door Fitting

[@scottvirgogp]

This content is getting better and better - smashing it chaps.

[@steadfastandyx4947]

I've commented before on your damp proofing. I'm convinced that there would need as much water falling, or rising, as when Noah built a boat. No water or damp is going to penetrate the structure. Still fantastic seeing the brilliant work.

[@Mr_A_Builders]

No one here can disagree with that Andy but because we are below ground on two walls it’s more of a belt and braces approach and with a warranty it keeps the customers mind at rest

[@w.o.o.d.y]

Behind the scenes proper building. Nice one guys, and thanks for the "warts and all" approach to the project. Opening the eyes of many a client here with what could be needed with a building project.

[@Phil.I.Am1]

QQ fellas - how would the tanking drain exit the building in a true underground basement? Would it have to run to a soak away or would it need to find its way to the sewer/surface water line? Love the in depth way you cover every aspect - keep it up chaps 🎉🎉🎉❤❤

[@Mr_A_Builders]

Hi Phil. In a proper basement they would fit a sump pump at the lowest level normally in a hole and run a pipe to outside from it. The pump would pump water vertically to an exit point outside the basement. Hope this answers your question

[@Phil.I.Am1]

Perfect. Thanks so much for your reply ❤️❤️❤️

[@25zerotwo]

Was it just me who has audio slightly out of sync with video? Great watch though, was good to watch the process without the stress of my own basement being tanked a while back.

[@Mr_A_Builders]

Right at the end was a bit out of sync but I didn’t realise that until it was too late. Not sure why it happened. At least I know somebody watched the whole of the episode

[@chrislangridge8370]

Great video. One comment about outer frame being wider than window/ side panel outer frame. Ask suppliers to use heavy duty outer frame so outer frames are the same, makes it easier for Matt.

[@Mr_A_Builders]

Thanks for the advice 👍🏻

[@tkthebear984]

Great video Rich, I’ve never really understood tanking apart from that it is a moisture barrier and I didn’t realise that you had to install a channel to take any water entering away. Great explanation and I have a better understanding. Great stuff 🙂👍

[@s.wilson5675]

The only thing to say here guys is...... Tank you so much! 😁

[@Mr_A_Builders]

👏🏻👏🏻👏🏻😁

[@ir7868]

Brilliant video

[@brianlochrie3958]

As always superb. Weekend complete for me. Cheers Rich and Mat. What a job.... the Wednesday episode. Too look forward to from the other job now. Cheers 🍻

[@timherlihy5785]

Top drawer video.

[@simoncarney9944]

Nice video Rich, well explained about the damp proofing! Exciting times when you can be waterproof and crack on! I’m looking forward to next week. 👍🏼

[@drsmith6595]

That was a great point you made Rich on ‘following’ trades. So many times having to put right and/or compensate for poor work done by a prior ‘so-called’ tradesman 🤦‍♂️😠

[@donoconnor4204]

Basement is looking great already! I’m glad the door opening got sorted quickly. Must coast a small fortune all this, but certainly worth it. Cat flap looks great white! At least the cat will the route in!!

[@SBODevelopments]

Great insight as always gents & I’ve gained some knowledge on tanking that will no doubt come in useful in the future. Thanks again for sharing the content & have a great week all 👍🏻☀️

[@davidquirk8097]

When I installed Newton 300 lath at house refurb I did I went round with yellow line marker prior to the install and marked dots where I needed to put the 'nails' in. This meant that I could ensure centre of brick for every nail and speeded up the install ( which was good because when I did it the instruction from Newton was drill the hole, squirt in Newton mastic, put a ring of mastic on the dry side of the lath then drive the nail in, all pretty time consuming). We've been really happy with the result, twelve years later and not the slghtest hint of damp.

[@jayboo8495]

missed this by 4 minutes but have to cut the lawn. i will grab a cold beer and watch this in a bit. love having a new ep from the boys

[@Guig96]

Great video as always guys. Interested to know how they fixed the aqua channel together especially at the mitred joints.

[@noelkenny7504]

Fantastic work as always by all your team

[@DocteGaby]

Very interesting stuff! One question: it wasn't clear to me how the draining channel went in. I assume holes were punctured in the black vapour barrier that seems to wrap around them? Otherwise not sure how the water would get in.

[@stevenlivesey-lu8qh]

Looks like good episode guys have a great weekend guys

[@tonymarshall740]

Great video as always. Do you know how the mesh connects to the aqua channel? Or does it just sit next to it? Also how are the aqua channel section / mitres connected? Thanks.

[@PertinaxPertinax]

Richie re the tanking unless I missed it you haven't shown how they have jointed the ducting around the perimeter? when we last saw it it was laid in place, mitred and butted but not jointed, regards Nick

[@xcel3353]

Why not external wall tanking,sealing? External tanking acts as a barrier between the ground and the outer layer of masonry. It prevents moisture from forcing its way into the masonry through weak areas such as wall floor junctions

[@jjfarrell9349]

Good stuff. Would have liked a bit more detail of how the tanking gets penetrating water into the channel. In some places the channel appeared tp be behind your under-concrete DPM so water could flow behind the tanking sheet into the channel. In others your DPM appeared to be attached to the tanking sheet, then the channel placed inside it - I don't see the point of the channel in that case, no water can ever get to it. The floor tanking sheet is apparently now going to go over the top of the channel, so perhaps the assumption is that your DPM sheet under the concrete can (or will) fail in which case it doesn't matter where it is with respect to the channel.

[@davidharding3058]

Yer it's unusual to that conversation happen to be honest. As normally the person behind as normal got sort the other person's crap out. And what your doing is to your benefit for you to the quality. Sound job lads 🥂🏴󠁧󠁢󠁷󠁬󠁳󠁿

[@includenull]

You've left a few windows in place in old walls rather than removing and bricking them up. Is there any particular reason, I would have imagined filling them in would have been quick and made things easier.

[@stevemull1673]

Always a top vid and job.👍

[@Stormin_Mike]

Is that Dave Gilmour in the yellow trousers?

[@ir7868]

Hi rich How they joint basement water drain mitre joint ? Some kind of glue ?

[@Mr_A_Builders]

On all joints they use something called Butyl rubber tape. It was mentioned in the video 👍🏻

[@smithbrownjones]

Silly question....but why don't you put the tanking\sealing on the exterior of the wall....? I've really only seen videos of how they do this in the States..... 🤷‍👍

[@Mr_A_Builders]

You can’t get to the walls to tank externally 👍🏻

[@smithbrownjones]

@@Mr_A_Builders Cheers. I must have missed that episode... 🤦‍♂️

[@Onhere6381]

Big old job this is - thx for videos

[@paulf2529]

Interesting seeing the tanking process, not something I have ever been involved with. The tape backing paper strewn around at 28:03 though would have driven me crazy, i like to have a empty one ton bag to hand for this sort of waste and put it straight in rather than having to pick it all up later.

[@Mr_A_Builders]

Sometimes you just have to get on and tidy up at the end. It’s only paper so doesn’t cause any major problem I’m a person that loves a good tidy up so it wasn’t there long 👍🏻

[@clivelockwood3236]

Looks like any water coming through the wall will end up under the concrete floor so what's the job of the plastic chanel .

[@m0nk3yl0v3r]

15:24... somebody fed Gizmo after midnight!

[@rossdiggle]

Proper coming on now.

[@paulf2529]

With the cat flap, sand it lightly with 180 grit sandpaper then a coat of zinnser bullseye followed by a coat of dulux trade satinwood in the closest grey you can match too. The satinwood finish is close enough in sheen to the pvc foil, I have done this several times now.

[@leeedwards9994]

hey fellas hope you all had a good week .....

[@willlister9825]

Looking great! Never knew that tanking was so involved after watching the garage conversion episode! Did the vertical channel you cut in the blockwork on the utility room side ever get used for something? Can't remember what the purpose of it was now, sorry! Keep up the good work!

[@michaelbolt4530]

Daft question, can you drill through it if you need to fix stuff to the wall without ‘upsetting’ the tanking

[@Mr_A_Builders]

You can’t no. We have to put walls in front of it but you’ll see that next Sunday 👍🏻

[@michaelbolt4530]

@@Mr_A_Builders nice one

[@HarleyN93]

How is the water going to get into the channel when the dpm would stop it or am i missing something? Shouldn't the plastic drain/channel be behind the floor dpm to allow it to carry water away from the walls the way you seemingly have it would just let the water build up behind the membrane with nowhere to go

[@buzzkillington3354]

Interesting ive never seen tanking done before

[@stu9070]

👌✌️👍

[@Swwils]

Why are the windows and doors so far forward in the reveals? Your boards are jsyt going to reach the outer blockwork.

[@lestercranmer2631]

Matt I do walk round with a level, I have an App 😀

[@karlj8418]

Shouldn't the tanking drain have been inside a channel in the concrete floor to collect the water? The way it is installed water will flow under the insulation, Any attempt to flush will pump water under the insulation as well.

[@25zerotwo]

Think the aqua duct is sealed at each join, so it will stay within that channel. There are trench versions, which include a sump, but given how this floor will be built up, the system seems wiser.

[@clivelockwood3236]

that's what i was thinking, surly the channelling now is doing nothing.

[@RS-ei3yt]

I hope the team can comment n clear this up

[@karlj8418]

@@25zerotwo Maybe but the water will go to the lowest point and the floor I assume is level. This means the water needs to get up to the exit drain height which is at least 10 -1 15 mm. I would have nice to see the flush demonstrated before the insulation was placed down

[@karlj8418]

After watching again, he says they will put the membrane all around it. That did not happen the membrane went behind the dmp. This means all the water will go behind the dmp. I don't think the drain has much of a purpose apart severe flooding mitigation. If the insulation gets wet will it dry, will it affect the performance?

Don't need a spirit level, just let the wife in the room. She will soon find what's level and what's not. Your voice is out of sync at the beginning.
