Hi all

New to the forum so hello, please go gentle, and let me know if I'm posting in the wrong place?

We've recently had an extention, during which we also had the kitchen, utility and all three toilets refitted and retiled. The builders organised or 'did' all the work throught the build, which in hindsight was an error as we've since had a minor electrical fire, and two small leaks amongst other things :(

Latest issue is tiling. Tiles have been down 9 months without issue, but in the last two weeks we've had 5 tiles become loose, across 3 different rooms. Grouting is clearly breaking and coming out making them porous.

My main concern however is the underfloor heating. Presumably if the tile is moving, I'm risking the cables breaking?

Short of ripping it all up and starting again. Is there anything I can do? Unhelpfully we streached ourselves with the build, so with corrections to date funds are limited.

Upstairs floors are chipboard, followed by cables, screeding, adhesive, tiles. = 4 loose tiles, 3 of which in a group.

Downstairs is concrete, 6mm insulation boards, cables, screeding, adhesive, tiles. = 1 loose tile.

To my knowledge they used flexible adhesive etc.

Any advice would be very appreciated? Let me know if I've missed any details?

Thanks!

Morning!

Not much to see on photos but please find attached?

I've also attached pictures of adhesive & grout.

Primer was 'Prowarm underfloor heating primer' which looked, felt, smelt like PVA glue??

Not sure what Sls is?

I'm thinking getting builders back out not really an option 1) if they didn't do it right the 1st time why will they the 2nd /3rd? 2) unsure if they'd even come back again. I see that as just being stressful to be honest

Very disheartened and fed up with it all tbh.

Thanks
James

not come across that adhesive before, the spec says it's suitable for

Sealocrete Rapid Set Flexible Floor & Wall Tile Adhesive is a cement-based adhesive for use on concrete, concrete block, cement render and brick. It can also be used on plaster, plasterboard, chipboard, wood and existing glazed ceramic or vinyl tiles and is suitable for use with most domestic underfloor heating kits. For internal and external use.

big claims there :eek:

I'd get onto the builder and also talk to sealoctete direct and get them to come out
In reality do you think it would get me anywhere calling Sealoctete out? I don't think I'd get anything but stress with the builders?

So are you thinking it's the adhesive at fault? I was assuming it was due to being layed on boarding? Although that doesn't explain downstairs with the concrete flooring...

Other than ripping it all up and starting again do I have any alternatives?

Thanks

You’ve asked and the replies seem to lead towards getting the builders back!
For whatever reason you seem reluctant to do so, but legally they have to have the opportunity to put it right.
Put everything in writing and keep copies, you will need it if action is required through the courts.
Your alternative is to live with it!
