Company History

The year was 1989 and George Herbert Walker Bush took the oath of office as the 41st President of the United States.  In that same year, a young man named Mark Topp, along with T.R. Johnson and Bob Johnson, started a small company specializing in environmental and civil construction.  They named it COMANCO, an acronym for COnstruction MANagement COmpany.

Coincidentally, 1989 was the year the first of 24 Global Positioning Satellites launched into orbit. Years later, COMANCO adopted the technology to provide real-time updates displaying the job as it progresses.   With the help of proprietary software named CAAB, developed by COMANCO, we can produce a finished drawing, detailing the location of every panel, elevation, and repair of the finished project, with incredible accuracy.

In July 2005, COMANCO moved its offices from Professional Place in Tampa to our new campus at 4301 Sterling Commerce Drive in Plant City, FL.  Over the past 30 years, the company has grown, expanding its reach across the country, including the establishment of an office in Reno, NV.  To keep up with demand, the workforce has grown to more than 300 experienced, well-trained employees, many of whom have been with the company for more than five years.

Recognized every year since 2004 by Engineering News Record as one of the Top 200 Environmental Companies in America, COMANCO has completed more than 3500 projects and installs more than 100 million square feet of geosynthetic liner every year.
