CONSTRUCTION MATERIALS TESTING SERVICES

The Construction Materials Testing Group has long been a beacon of quality and integrity for contractors, owners, engineers and architects in Missouri, Illinois and Kansas. Geotechnology’s construction materials testing services play an important role in the successful completion of many Midwest landmark construction projects. The Group is widely considered to be the area leader in the testing of concrete, asphalt, steel, soils and other construction materials. Our field representatives hold Level I, II and III certifications from ACI, NICET, ASNT, API and AWS. The laboratories are approved by AASHTO and CCRL and hold U.S. Army Corps of Engineers validation. The Collinsville, Illinois lab is certified by the Illinois Department of Transportation.
