About Us

Ellerbee-Walczak, Incorporated (EWI) was founded in 1990 as a full service Construction Materials Testing (CMT) company. EWI’s business approach and philosophy is based on the premise that a concise and accurate testing service for our clients is of paramount importance.

EWI assures our clients fast and reliable distribution of test data, quality customer service and responsiveness. We take pride in being able to offer these services to each and every one of our clients. We understand in construction that scheduling doesn't always go according to plan, therefore in order to serve our clients we are able to schedule a technician within an hours notice.

Our Geotechnical, laboratory and field services are performed by Certified Engineering Technicians under the supervision of licensed Professional Engineers. Periodic inspections are made to verify laboratory test results and ensure that our Firm meets the requirements of ASTM E-329. A host of client referrals are available upon request.
