Remodeling / re-purposing concrete floors in a facility may or may not require extensive repairs to the flooring to meet your new specifications. This is where it is important that I see the floor and thoroughly review your options with you. There are often several levels of restoration available to meet your specifications and your budget.
Restoring an old or improperly installed / failed seamless floor requires experience and an in depth understanding of the conditions that cause early failure.
A word to the wise: be wary of the claims we see online for seamless flooring alternatives that can be installed over almost any surface in just a day or two.
