Safety is one of our three core values and ingrained in COMANCO’s corporate culture.  The personal safety and health of each employee are of primary importance as evidenced by COMANCO’s safety record, with a 0.78 Experience Modification Rate (EMR), issued by the National Council on Compensation Insurance (NCCI).

COMANCO understands that safety is more than just numbers, it is personal.  To that end, COMANCO has set a goal that 100 percent of COMANCO employees receive a minimum of 10 hours OSHA training. Currently, more than 98 percent have met this requirement.

COMANCO maintains an Environmental, Health and Safety program, conforming to the best practices in our industry.  An EHS Officer is assigned to oversee operations and observe first-hand that safety procedures are implemented, and potentially hazardous working conditions are corrected on each jobsite.

The key to accident prevention is situational awareness. Employees are constantly reminded that accidents occur when they fail to observe what is going on around them. Each employee has ‘Stop Work Authority’ if they identify a dangerous condition.  More importantly, they are trained to recognize potential hazards and to make better decisions.

The bottom line for COMANCO’s customers:  Fewer reportable incidents mean greater productivity and minimized risk.  At COMANCO, safety is always our first concern.


Quality is a word used by everyone but understood by few.  At COMANCO, Quality equates to Value, and that is our competitive advantage.  COMANCO follows a strict quality control protocol and has set minimum test requirements that meet or exceed ASTM and the Geosynthetic Institute, (GSI) standards.  Actual Cost is evidenced by the long term cost to maintain and replace an installation that has failed.

Our Quality Control and Assurance Team are vigilant in their pursuit of excellence.  Over the past 34 years, we have developed an extensive and thorough quality control program using advanced testing equipment, designed and built by COMANCO.

COMANCO’s commitment to quality is evident in the many installations currently in service throughout the country; they continue to perform with no reported complications.

COMANCO employs the latest technology to provide accurate reporting of every aspect of the job, using a proprietary computer program called GeoCAAB. This system provides a useful material management tool, by providing the customer with an AutoCAD® (.dxf) file. This file contains all the details of the project, including the location of each panel and every repair, including a three-dimensional drawing that displays all the elevations.

Our dedicated quality control department conducts training for all new personnel and continued training for all field employees. This training provides maximum oversight and monitoring of every job to ensure all documentation is completed and meets COMANCO’s high standards.
