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.

Dr. Coleman serves as a Consultant on the Sam Houston Ship Channel Bridge Program in Harris County, Texas. The current bridge is being replaced with wider twin spans. The project is expected to take over six years to complete. It is the biggest infrastructure project in Harris County.


Dr, Coleman has served on the Advisory Boards of:

  • Lyles School of Civil Engineering, Purdue University from 2007 to 2013, and
  • Department of Civil & Environmental Engineering, Prairie View A & M University from 1998 to 2005
