About C3S, Inc.: Concrete Consulting Service

C3S, Inc. is a Houston-based concrete consulting service founded by civil engineer and concrete specialist, Dr. Ebow Coleman. Since 1991, we have been providing clients around the world with expert evaluations of concrete through methods such as petrographic analysis, scanning electron microscopy (SEM), X-ray diffraction and field testing procedures.  We perform concrete evaluations during all stages of project planning and construction, as well as several years after the structure has been in service.

The name 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 feel that the name reflects the importance of our services.


Our Mission

In the planning phase, our goal is to help stakeholders of construction projects prevent costly repairs. Our forensic skills and civil engineering background allows our team to determine which construction materials are best for the structural stability of the project.

If structural failure has already occurred, our mission is to use innovative forensic techniques to accurately determine causes of construction failures and to recommend appropriate and cost-effective repairs
