Sunken Grout

[SJPurdy]

8mm wide grout line for 600 x 600 mm porcelain!
We really need pictures or at least details of the type of tile (make, pattern etc.) to be able to give an opinion on this.

I would very much doubt they are 8mm joints and a 3mm dip, I'm sure That's just a guess, as said pics would really help in this situation for the right advice to be given! I wouldn't rush into getting any power tools on the job just yet. If the joints are really that low they can be 'topped up' as for the poor cutting etc again pics would help us to see if it's generally acceptable or just how bad it is.
