After interviewing many local, regional and national property managers, facility, operations and owners throughout the United States, DIAMOND was created to meet the needs & issues that we have uncovered to improve the experience of purchasing pavement services.

With DIAMOND by GemSeal, Property Owner/Managers have a centralized place to find Compatible Pavement Contractors based on many types of search criteria including geography, type of services, previous work history, financial strength, insurance coverage, materials used, equipment, warranties provided and specific skills.
