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.
