Certified Testing Laboratory
Our cross-trained staff use an extensive inventory of equipment to complete many types of testing to meet simple and extremely complex client needs
With three in-house laboratories, currently located in southern California allows us to process large volumes of samples and be more responsive to our client’s needs when fast turn-around times are needed. Incorporating technology and proactive management practices, we are able to significantly reduce the lag time in generation and distribution of laboratory and field reports, which are essential for adherence to critical path schedules. Our laboratories participate bi-yearly in Cement and Concrete Reference Laboratory (CCRL) Sample Proficiency Testing and consistently achieve the highest possible ratings.
