Once we are aware of the problem, we will proceed to repair cracks in the concrete floors by milling, cleaning, and sealing. These tasks are part of the set of renovation activities, through which superficial flooring problems are solved. We start by milling the cracks or fissures and subsequently cleaning them. Next, concrete cracks are sealed with a resin component for interiors or polyurea for exteriors. Sealing cracks in concrete floors avoids water and any other external substance to penetrate the concrete, thus helping to maintain its support capacity.
