Improper sealing or curing of the concrete on the surface may result in excretion of moisture, oil, or grease that result in the gradual disintegration of the floor. An excess of bleed water at the time of finishing work results in extra water rising to the surface, and this carries finer concrete particles, resulting in a fragile and softer layer.
