One of the strengths of university-government-private sector collaboration is the opportunity to share costly instrumentation. The CIGMAT researchers have access to unique equipment not generally available for work in the area of grouts and grout applications. Some examples of state-of-the-art instrumentation and specialized testing capabilities are given below. Other instrumentation at UH may, by special arrangement, be available through CIGMAT.
