We are in the process of a new build with a polished concrete gympie floor. The slab has been recently laid and due to problems with it probably being let to cure too quickly, it's badly cracked. The builders want the option of filling the cracks but all my research seems to suggest that the repaired cracks will be visible. What other options do we have? They have suggested we start thinking about alternative floor coverings but we just don't want to do that.
