We hired Tharle to do a new slab for 2 units we were building that was going to have polish concrete with minimal aggregate exposure. The slab was poured and was uneven and grinding companies said that given the issues with the slab full aggregate exposure was necessary which would have not provided required result. A full grind to aggregate was also 6K more expensive. An alternative service was provided that would create a 6mm topping layer over the concrete to recitfy the works. This would cost $8K over the original grinding costs allowed for. Tharle was initially responsive about the issue but after looking at the slab and verbally admitting that there were issues with the work and the pour, they stopped responding to phonecalls, emails and texts hoping to come to an agreement on the additional costs required to rectify their works. Dispensation to be sought though VCAT.
