DBI has an extensive experience base with Glass Fiber Reinforced Concrete (GFRC) cladding systems and interior and exterior fiber cement board systems. Specifically, Mr. James Daniel (founder and Sr. Principal of DBI) has extensive knowledge of fiber reinforced cement board technology used for interior tile backer-board and underlayment and for direct-applied exterior finish systems (DEFS). While at USG Corporation, he managed the Exterior Systems Laboratory significantly contributing to the development of the Durock Cement Board interior and exterior finish systems. He is past Chairman and current member of the American Concrete Institute (ACI) Committee 544 on Fiber Reinforced Concrete, past Chairman of ACI 544 Subcommittee on GFRC, current member of ACI Committee 549 on Thin Reinforced Cementitious Products and Ferrocement, and has authored numerous publications on fiber reinforced concrete (FRC), Glass Fiber Reinforced Concrete (GFRC), and fiber cement board systems. He has investigated hundreds of non-performing GFRC cladding panel systems and cement board systems involving panel cracking, tile cracking, exterior DEFS cracking over fiber-cement board, water leakage, and finish delamination issues. As a consultant, he has continued to assist major cement board manufacturers with new product development. In addition, working for Marriott, he managed an in-plant and on-site GFRC quality assurance program for the manufacture and installation of GFRC panels on two of the world’s largest GFRC-clad buildings; a 42‑story and a 48-story Marriott Hotel.
