w.i.a.tile
Hope you can help me with this one.
I bought a new house 2 years ago and had a 600 x 600mm porcelain floor installed, tile approx 10mm thick, total coverage 25m2.
All was fine up untill about six months ago when i noticed movement in the tiles when anyone stepped on them. The grout joint around the tile is about 1.5mm wide which i understand is small but i believe needs to be tight for the final finish with this type of floor.
Sounds bizarre but holes in the grout keep apparing all over the place.
No tiles have cracked but they do sound hollow when you tap them with someting.
the floor substrate is a timber floating floor which was then over laid with marine ply 18mm thick and fixed every 6 inches.
the tiles were laid with a serrated trowel bed as i watched the tiler from time to time and i was very impressed with the end result.
I am begining to suspect that the tiler may have used the wrong adhesive and or grout which is contributing to these problems.
please advise adhesive and grout choice for this floor tile and for this substrate.
all i want is to get my floor back to how it was, if it means rip out and start again then so be it.
please help.
P.S. if i do rip it out and start again i will probably install electric underfloor heating. Please could you advise if this will have an effect on adhesive and grout choice.
