Dr. Coleman founded the company in 1991 about ten years after graduating from Purdue University in 1981

He holds a Bachelor of Science degree in Chemistry from Kwame Nkrumah University of Science and Technology in Ghana (1972), a Master of Science degree in Cement Production Technology from the institute of Chemical Technology in Prague, Czech Republic (1977), a Ph.D. from the school of Civil Engineering, Purdue University (1981) and an MBA from University of Houston in Texas (2000)

He has more than 35 years’ experience in cement, concrete and related materials. He has worked in research and development of oil well cements and holds two patents in this field. His work in producing durable concrete for structures covers the entire spectrum of concrete construction, namely, project planning phase, construction phase and maintenance of structures.

Dr. Coleman performs forensic evaluations for several concrete structures in distress. He has been designated as expert witness on more than ten occasions.

We offer structural testing services, without causing any damage or destruction. These include UPV testing, GPR mapping and corrosion scanning. Check out our solutions for concrete structure repair.

6. Modern Material Testing and Analysis

Whether you want to test the compressive strength of concrete or soluble chloride content, we have testing and consulting services for all concrete issues. With the help of forensic evaluation techniques, such as XRD, we can precisely determine the cause of any issue. We also make use of petrographic analysis for best results. We use scanning microscope imagery to check the tiniest details. In addition, to check weight changes in the material due to temperature, we use thermogravimetric analysis.

Unlike other concrete maintenance consultants, we do not do any guesswork. When you choose our consultants, we use only cutting edge scientific techniques to determine problems in the concrete ingredients used for construction. These analysis services help determine concrete mix & design of the structure.

7. Litigation Counsel

We also offer litigation support, including field research, depositions, expert witness testimony, and case evaluations, related to any defects in concrete construction and structures.

So, whether you need concrete evaluation services for a roadways project or the cracks in your garage, contact us now! We take pride in providing the highest quality of services every single time.


Allen Browning, M.S., P.E.

Our company worked with C3S Inc., on several projects. The services provided by C3S Inc. in regards to Petrographic Analysis of concrete cores from damaged areas were vital to the evaluation.

In our opinion, C3S, Inc., not only provided reliable information, they also did it within a short amount of time to help maintain timeframe and budget limitations.

MTA Engineers consulted with C3S on several commercial, state and federal projects. Most of the projects have been related to issues with concrete or quarried stone. The response from C3S has been timely and accurate. MTA will continue to contract with C3S on future projects.

Paul L. Roberts, P.E.

C3S, Inc. was contracted on our Harbor Villa Project. This property in Honolulu, HI, required evaluation of the structure to determine the existing damage and remaining service life pending a planned renovation. The report was very comprehensive and was received in a timely manner which enabled the project to move forward quickly.
