A substantial part of the research activities developed at CERIS aim at improving/developing innovative products that can be applied by the construction industry, improving its competitiveness. This was achieved, along the past years, with many funded research projects involving CERIS and construction companies. From these partnerships, new Products or Prototypes, New Materials, Patents, Software Solutions, Special Testing Techniques and Expert studies were developed and implemented in private and public works. The following works illustrate the strong collaboration between CERIS and the construction Industry: i) products and prototypes; ii) development of materials; iii) software solutions; special experimental tests; expert studies; and patents.
