Need some advice on new build !
Have had several problems with quality, PB has been out 6 times to correct horribly set tiles and I suspect that coping is also an issue. I have OK flagstone and after install (2 weeks ago) I have noticed a hollow sound when tapping on about 50% of the stones. After reading some of the forum posts I suspect that the flagstone has not been set correctly. I am tapping the stone with a wooden broom handle and hear a distinct hollow sound and have also observed that the stones vibrate under foot. There also seems to be a fine crack between the mortar and the stone at the tile mortar/ grout line on the pieces that are hollow/vibrate. The solid sounding stones do not vibrate or have the fine crack at the tile line.
Should I be pressing the PB to reset the stones in question prior to the plaster being installed? I wonder if I am being to picky at this point due to all of the other issues that have been experienced thus far.
