Helping to Build Foundations for the Future
Materials Testing Inc. and it’s subsidiary KC Engineering Company was formed by Douglas G. King and David V. Cymanski in January 1996 and has grown to be one of the most respected engineering consulting and testing firms in the northern California region.  Two new principals were incorporated into the management structure, Andrew L. King and Maurice M. Mathews.  With over 36 years of combined experience, we have participated in the development of numerous sites with varying topographic and geologic conditions from initial site history and resulting subsurface soil investigations to quality control and quality assurance during public and private improvement construction.  This experience drives our company to support our clientele with the ability to evaluate new projects and contribute intelligent, common sense driven, geotechnical engineering, materials testing and special inspection services during construction.  Our strength is based on our entire staff of professional and staff engineers, certified technicians and inspectors, and supporting administrative staff working together to provide excellent client service, practical and cost-effective solutions, and timely reports.  Our work is thorough, well organized, timely, within budget and of the highest professional quality.

We are a Certified Small Business with the State of California Department of General Services (Ref #23181).  Our business philosophy is to provide exemplary service to our clients and to surpass it future projects.  Our engineers are licensed to practice in the State of California and Oregon as Professional and/or Geotechnical Engineers.

The services provided in both our Vacaville and Redding offices includes geotechnical, geologic, environmental, materials testing and special inspection services.  We strive to meet the ever-increasing demands of clients who expect the best in engineering services and conformance with the state of practice. Our offices have a proven record of responding quickly and efficiently to the needs of our clients.  We recognize that our field is one that continues to evolve, especially in the field of earthquake engineering.  In order to keep up with the latest technologies and engineering data, our engineers attend technical seminars on a regular basis and consult with others in the field and our industry.
