The Center for Innovative Grouting Materials and Technology (CIGMAT) Research Center was established in 1994 at the University of Houston, Houston TX. CIGMAT’s goals are to foster improved understanding of grouting and coating materials under various applications. Also of interest are other competing and complementary materials and technologies to grouting and coatings used in the construction and rehabilitation of civil infrastructure and offshore pipelines.
