Floor covering failures are often a time-consuming and costly problem that can decommission a facility from its intended use. The problems may arise from improper installation practices, excessive moisture in concrete slabs, and from deterioration mechanisms such as alkali-silica reaction. DRP has experience working with floor covering failures in medical, industrial, food preparation, and aeronautical facilities as well as residential settings.
