Self Levelling Help - slab split into two?

[Ajax123]

Thanks for the reply.

The angle of the picture doesn't help, there isn't really a chasm, the two joints butt up against each other. There is just a height differential.

I haven't seen anything about a low viscosity resin stich in my research, is it quite common to use this method? I did consida Ditra matting as I have used this before, but at 20m2 it will add significant cost.

Resin stitching is a very common method of repairing unstable or fractured screeds.

Thanks for all the advise.

I have taken another close up of the join.

The previous tiled floor was fine for the 3 years we have lived here, it would be sods law that it cracks for me after the laying the new floor!

Yep you can bet it would move now!!!!

I will probably do the lot in uncoupling membrane to be on the safe side, £200 is better spent now than trying to dig up the tiles later to fix 🙂

Appreciate all the help chaps!

Not a bad decision. Belt and braces job!
Go to to www.radetiler.co.uk and use the durabase ci matting. Great stuff and a good price, and Dave's a very helpful fella. LAy the mat as above and leave overnight (even if you use fast set), and tile the next day.

Just reread the thread, Mapei Renovation is the best leveller i've used. Pours nicely, but i've not gone to depths of 30mm, it may take you a few pours over a few days to get it just right.

You could use a gypsum screed to 30mm but maybe that would just complicate things.....
