How To Install Cavity Trays

- Cavity Tray tutorial on a garage abutment. Cavity trays are easy once you understand the basics. One of the key requirements is a dummy truss/guide or ideally the actual truss that is going to be used to form the roof at the end of the job. No amount of guess work, experience of expertise is going to give you the correct positioning without the correct guide. You can download my Cavity Tray guide from my Shopify account, link is below.

Good video quick question how does anyone clean out the lead trays when you're building the gables and I have never seen water come out of a weep holes thanks
Before building gables a cavity tray should be installed so bottom of the tray is a minimum of 300mm above the bottom of the truss. With good cavity protection and cleaning trays in each lift the trays do and will work! Weep vents quite often need a poke to clean them out
Throw a bucket of water into the cavity before the mortar dries
@@lukeregan8260 Noooooooo 🤣
What wrong with cutting in lead when u have roof line cheers
@@walshblocklaying1251 It does not stop the water running down the back of the bricks and going into space below. Not so critical on a garage but if they room below is a living space, such as a bay window, porch or something then cavity trays should be installed
Old school can't beat doing trays with damp course 👍
I was never a fan of damp proof course trays! personally I don't think you can beat the leaded cavity trays 👍🏻
By far the most informative bricklaying tutorial on youtube .Thanks lads keep up the great work .
Thanks mate, we try our best 👍🏻
This really helped me, just about to do stepped trays, but didn't have a clue!😅
Glad it helped. You can download my guide, and others, from my store 👍🏻
Great video. All to detail 👍🏻
Thanks Alex 👍🏻
Nice video mate 👍👍 it’s acrually nice to see someone put them In! I still see many where there missed out and then the lovely brown mark(water stain) comes in on the ceiling below 🤯 if I lived closer mate I’d Defo come and work for you 💪💪 blokes like myself that actually want to do a decent job 🙌🏻
Thanks mate 👍🏻 we don’t get it all right but we do try 🧱👍🏻
oh your boys are spoilt!!! ive got one inside board 2 boards would be a dream!
Always two inside boys mate 😂
We keep it around 180mm above truss line!
Also cut a 25mm strip of expansion foam to put under the tray same level as mortar bed under the tray then the roofer pulls that out and slides his lead in!
We try to use the trays with the foam built in that the roofer can pull out when he comes to lead the trays but they aren't always available. 180mm seems quite a bit, does the lead man ever moan about the amount of lead upstand? Tile depth obviously comes into it and I don't know what tile you are using so not saying you are wrong 👍🏻
Superb mate another top notch video and explanation. That’s tidy work there on them trays respect. 🤟
Thanks mate 👊🏻👍🏻
Put them in last week but had no truss & joiner's wouldn't make me a pattern spar so had to follow the tray guide. Brick should go on tray dry as well not bedded.
Trays need to be bedded on and bricks bedded on tray mate, not dry bed the brick
Very informative 👍🏻
The aim of the game
Excelente trabajo 👍👌⚒️💪🧱
Thanks 🙏🏻
Great job 👏🏻
Thanks. What was your favourite bit?
Enjoy the videos, using template for cavity trays tomorrow worst luck, like to send you a few pics how we do it if that's okay works all the time
On to a winner if you have a template 👍🏻 email pictures to admin@aanddgroupltd.com and I will post them 👍🏻
Great video 👏
Thanks 👊🏻
Step trays quiet easy to do as long as your first one set right and like u say 150 to coner of tray each time u dead right keep smashing it mate 🧱 👌
Easy when you know how mate 👍🏻
Won't you see the closer you put upto the weep hole on the catchment tray?
Sometimes yes but the position of the catchment tray must come first unfortunately. You can normally get them to work bricks but not all the time
I use box sections, if you need a gang to offload that dori onto ;)
Will give it a review when we are using some box profiles mate, although Liam has got a couple of them. They are handy for when you have projections which we have coming up on a new job 👍🏻
If it’s blown in insulation, doesn’t it fill up the trays ?, great video 👍👍
It will do but they still do the same job 👍🏻
💪🏽
🫡
Thank you!! Now rather than arguing with people I can just show them this video.
👍🏻
How do you tend to do retrofit these stepped cavity trays? My builder is reluctant as it’s a lot more work than he had planned.
It’s actually fairly easy, only a few bricks need to be removed at any one time 👍🏻 I can understand the builders reluctance but they are quite easy
Are those brick ties, wall ties, stainless steel? They look shiny.
Yeah man
Where’s the dori from pal ?
Good tray guide ! I’m on a site where there isn’t profiles for many bays and garden rooms so it’s guess work and it’s not right or fair on us price gangs
The dori block is from BT Engineering but they aren't out just yet. George gave me a couple to sample, hence we didn't know what we were doing 🤣We do not build any bay windows, garage abutments or another other abutment without a dummy truss at worse, most of the times we try to get the real truss. If there is no dummy, the lift gets left until there is one 👍🏻
@@Tone_Team we have garden rooms attached after so the front is still and apex steel the. The joiners build to that so it’s hard to get the right tray form when there isn’t any dummy frames
@@TTV-blit Nothing worse when nothing to build to, virtually impossible to get them right! Can't you rack away until you at least have a guide? We have one particular house type like that, we have to rack away from a cat slide roof and then when the trusses are spread we drop back and fill in the trays
@@Tone_Team can’t rack back as the 1st tray is half a brick in from gable then about 15 bricks long to other side of garden room roof . Bad design (jones homes , barbridge)
@@TTV-blit I suppose when you have done one you can always look back at that for reference! I’ll have to remember not to price for them guys 😂
Where did you get that dori block mate? They would be mint for the job im on .
George from BT Engineering dropped them off when he was over from Oz, they aren’t available just yet
Sweet i will keep an eye out for them hitting the shop cheers 👍👍
@@Johnboy891 great bit of kit now we know how to use them 🤣
What are those type of dori blocks called?
Not sure of the name, they will be released soon 👍🏻 good aint they 👍🏻🤝
These videos are bang on ....following the pitch never works
👊🏻👍🏻🧱
That starter tray doesn’t work out right…to the other side of the lead you’ll have 3 straight perps to the left of lead only way it works is course higher or lower … unfortunately it didn’t work out did it only way that would of worked was reverse bond in the footings have had to do these things before to make things work right up above at least you’ll know on the next to set it out right
There is one straight joint where the starter tray is that can't be odds, one course up or down and the tray is in the wrong place. Important thing is the tray is in correct position, bond works it self out
Obviously it cant be course higher or lower …just saying the bond needed to be reversed for it to work and no bond works it’s self out its not on a fitness regime….it’s still set out wrong…. Let’s put it another way if you’ve got to build another house of them anyone in there right mind would reverse the bond from the house you’re building now and you know damn well there’d be no problem like you’ve shown
@@johngarthwaite4051 oh Jesus Christ you are trying to tell me that we need to work out the bond for the lead trays when the house is bought up to damp. I’m sorry mate but your way out.
@@johngarthwaite4051 honestly this is the most ridiculous comment I’ve had to date. We don’t even get them to damp. There’s a bay window on the front, what if reversing the bond alters that bond. I literally give up trying to put out educational content. You’ve beaten me.
A lot of it is down to the architects they know these problems and don’t let you know I’ve had it before where good ones have come to the job and explain and others let you find the problem yourself …anyway I still like your videos and they are educational…promise I won’t have any more problems ✌️
🧱
Just another brick in the wall
Hame them plaggy trays😂 do they even work🤷♂️😂😂😂
We find them alright mate, better leaded but everyone steals the lead 😂
@@Tone_Team yeah I can imagine they do😂
Have you ever seen a finished house with cavity trays work?
Or should I say have you ever seen a house without cavity trays have a problem with damp threw the head of a opening mate?
@@craigstyrin3453 They do pose us a few problems in all honesty but we are much stricter on them now, we have introduced a much stricter inspection process as they are a nightmare to fix retrospectively! Ive got bay windows on my own house that I'm about to start building 🤣
@@Tone_Team yeah I’ve seen your doing your own house, exciting stuff!
Be doing Flemish bond and loads of detail work 👍🏻👍🏻👍🏻
@@craigstyrin3453 I'm not good enough for that 🤣
Them plastic trays ain’t worth a wank, even yovil trays are shit, build them over bay window, and you get nothing but problems, only way is fully lead trays
I do prefer the leaded ones but every fucker nicks the lead 😂 you stand a fighting chance with leadless trays if they are at least installed correctly
