hi, i had a bathroom done 2 years ago, new floor with new tiles... I

If the problem was insufficient support below the tile, I would expect
the grout to crack here and there unless the floor moves like a
trampoline. �I suspect it wasn't properly mixed - too much or too little

I dont have any photos to provide.. More info... The bathroom was a
total demo job.. New floor... We used Travertine tile... The problem
area is on the bathroom floor, not shower stall.... This are the big
travertine tiles... He used Macpei unsanded grout, b/c of the small
joints... I noticed some areas, not all, that were like, "cracked"-
the grout that is... 2 years after the job.. He chopped it out and
layed new grout...Sound like poor installation? He says that since its
2 years old that can happen to grout- stupid answer??- Hide quoted text -

There's no doubt bigger tiles are a bigger problem, the floor needs to
be ever more rigid.
