It's sawn Indian sandstone…The "common" Indian sandstone is hacked out of larger pieces by children working in the quarries.

It now definately looks like sandstone but the piece on the left with a crack in it looks like limestone! Your blown up picture has identified a lot of grout haze and excess grout in the pits and fissures especially towards the front leading edge. I would take care to point it out to the customer beforehand as when you clean it they will see it as clear as dat because of the colour of the grout. I personally would clean it with a Mono Rotary coupled with a Medium Brush and an acidic cleaner subject to a test area first.Kev

After some one has re grouted it, I'm going back to seal it Darran
The grout lines need to be cleaned first before re grouting! Then it needs to be sealed, then grouted and then sealed again
