How to fix sloping sun room floor?

RobertG3046

Hello , and Thank you for accepting me in the Group.

We purchased Our House around 50 Years ago , the Back sunroom slab must have been built in two seperate slabs , and we tiled it , now the half of the Sunroom has a slope from almost straight to a slope of 35mm  so no longer the sliding door can be used.

Was looking at Self Leveling Concrete  , or maybe Pebblemix .

Can someone give us on Ideas how we could over come this

Than You for all Ideas and sugestions

Hi @RobertG3046 

Sounds like your 2nd slab is sinking which is a bit of a concern as to why for one and if you do any releveling work will it keep moving again is the question.  35mm in 50 years well could be worse and I would hope the movement is finished.

So, try to look at why the slab has moved just for your peace of mind.

Yes, floor leveller will work and probably the easiest, but you will need to apply it in 3 stages and let it set cured between stages as floor levellers tend to have maximum thicknesses of approx. 12mm Ie 3x 12 layers is 36mm close to your needs.

The  job might look best if the whole room  leveled for the final coat taking up the tiles first

Add a nice floor  re tile over the top , I would build in a gap or a planned fault line at the slab join in case of more future movement.

Bastion Floor leveller is probably the best bang for buck at $33.54 a bag.  

Pebble Crete will work at the deep end but won't flow to a feather edge at the other end and usually will need to be 20mm thick (look at its specifications on each product) to avoid cracking and the entire floor will need the treatment for a uniform finish but that is defiantly do able If you wish.

The  sliding door stuck?  Is this floor going up or down? Everything will change.
