Tile layout problem?

[Dan]

OK....

So the links you lot need are

www.tilersforums.com/scanl.jpg and www.tilersforums.com/scanlorig.jpg for the original (I tried to tweak it to get the numbers a little clearer).

The problem(s) why it didn't upload: 1, the file was the wrong type. It was .tif, always try to save image files as .jpg or .gif if you're uploading to the forum and 2, the file was HUGE - like 20 times that the limit of the forum attachment size. So those that can, please decrease the image size and compress the files if you can (good software will compress when you save the file automatically). Just for future reference guys and gals.



Feel free to email me any photo's though if you can't do it for whatever reason.

hi mick..where the two pillars are..if that is where the new floor meets the old.. you will need to put an expansion joint there mate......sqaure the tiles to the kitchen and work from there....good luck...

Many thanks for all your help in getting the scan on the website. I'll sort it out a better way next time.

The top part of the drawing ( where the kitchen is) is the new extension and as noted by yourselves the bottom half of the drawing ( between the 2 pillars and back) is the older 1960s part of the house where the kitchen and lounge have been knocked through together.

All the old floors are sound concrete and the old kitchen part ( bottom left of drawing has been latex screeded as it was about 5mm lower than the lounge when the wall was removed. Hope this makes sense !!

The new screed floor in the extension is the same height and level with the old build.

Slight panic, due to my somewhat problems with my earlier 5m attempt, I have had some quotes in to do the 50 metre l shaped area, None of them have mentioned an expansion joint !! Now I am worried cos these are pro tilers ?? Help......

Get yourself on www.findtrustedtradesmen.co.uk and get a couple of quotes from the tilers on there, which are tilers from this forum.

Though they may have siply not mentioned it to you as they wouldn'y want you to go off and do it now would they? - Although I would have done myself as it could have clearly secured the deal there.

Could be a nightmare if they tiled it as one though, needing at least that area pulling up and re-tiling with an expansion gap in it.

mick..Whwere you have a break in the substrate be it a new floor or an old floor meeting a new.. you have to put an expansion joint directly over this point as the two floors will expand at different rates thus causing the tile to de-bond.....

I think this will be another late night for me.
Thanks god for you guys, hopfully another disaster avoided.

Am I assuming that there needs to be an expansion joint between the new build screed and the original house concrete floor..
Are we ok without an expansion joint where we knocked down the wall between the old lounge and the old kitchen .
What is an expansion joint, and does the tiler do it. Should the builder have done it?
Gosh i really dont know what I'm doing now

Tried that forum but nothing found under my postcode, how do |I know if they are from this forum?
I was really looking forward to seeing this floor done but it is becoming a nightmare.

There should by rights be an expansion joint put between the two pads by the builder or who ever laid the pads..then the tiler puts an expansion joint above this joint....

Firstly an expansion joint should go where there is already an expansion joint in the substrate...if there is one..like this pic..

these joints can be filled with Silicon for light domestic use and you can use one the same colour as the grout...for high trafficked areas then a profiled expansion joints should be used..as in the pic...

These joints should go in about every 6 to 10 mtrs in either direction..this will reduce when tiling to heated floors.. these then become about every 4 to 6 mtrs in either direction....

If using the Silicon method ( also known as a cold joint ) then just keep the joint clean and dry prior to using Silicon....and if using the profile trim then it beds into the adhesive as shown in the pic.....hope this helps mate and good luck with the floor........

There is no expansion joint visible on the new screed, it was only laid 6 weeks ago, no mention of this on the drawing either. New screed laid level up to old existing floor. Do I assume there is not an expansion gap?

The pillars ( you mention pads) are where the back of the house was knocked out through to the extension.

If there is not an expansion gap visible on the floor waht does the tiler do? Have I got do have a "break line right in the middle of my new floor.

I am at my wits end now, as I mentioned I have had 3 tilers round to quote for the job and none have mentioned this.

Hi mick...obviously if the builders haven't put in an expansion joint then you won't see it.
You will just have to tile it really and hope for the best....
Unless a new floor was laid through out the old and new extension then as far as i am concerned an expansion joint should have been put where the old floor meets the new one...good luck mate and let us know how you get on....

hi mick dont gamble -put a 3mm colour matched silicon joint shere thr old concrete finished,i know you cant see it but you will have to work it out and get it as close as possible .this then dictates your horizontal lines [on plan] centre your vertical lines so it is nice and equidistent ,at2250, above all tell your customer what and why your doing this,as soon as you mention possible future cracks people become VERY understanding!
