About Us

C3S, Inc. is a Houston-based concrete consulting firm founded by civil engineer and concrete specialist, Dr. Ebow Coleman. Since 1991, we have provided clients around the world with expert, in-depth evaluations using advanced analytical methods to provide solutions to problems with concrete and related materials. Our services cover the entire spectrum of construction of concrete structures, namely, project planning phase, construction phase and maintenance phase of existing structures.

Our experienced team of engineers, inspectors and technicians provide our clients with thorough assessments of the concrete quality and the integrity of the structure. C3S staff is active in professional organizations and works with key industry leaders to provide clients with cutting edge concrete analysis.

C3S is derived from Tricalcium Silicate (C3S), one of the four principal components of Portland cement, a universal construction material. As concrete and cement experts on a global scale, we identify with one of the strength-enhancing components of Portland cement.

Our team is led by Dr. Coleman, an expert in concrete with extensive background in cement chemistry, petrographic analysis and, concrete testing. He has written several proprietary research papers and co-authored two US patents. His specialization in forensic evaluations of concrete and problem solving in cement plants has been useful for ready-mix concrete plants, facility maintenance, airport runways, highway pavements, commercial buildings, industrial structures, and educational facilities.

With over 25 years of experience in the construction materials industry, Dr. Coleman is fully equipped to provide an expert opinion during litigation, strategic planning of projects, and marketing.

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.
