During the inspection we were told that the contractor who did the floor refused to fix it as he could not find anything wrong with the floor !!!
There was no doubt that the existing floor coating had to be completely removed. We used PCD diamond blades to cut through the coating and then we diamond ground the floor to remove any laitance, profiling the floor. Cracks were chased open and 2 pack liquid epoxy filler was used to fill it up. Excess was removed by spot grinding.
