Materials Testing and Inspection
A Wide Range of Laboratory Tests and Observations
Connect Engineering’s AASHTO-accredited material testing laboratory includes a wide range of tests and observations performed in the laboratory and the field during construction to determine compliance with the project plans, specifications, and referenced industry standards. We handle material testing for residential, commercial, industrial as well as transportation projects. We can provide services on a continuous or periodic basis.
Connect Engineering performs a variety of testing services for soil, concrete, aggregate, structural masonry, structural steel and welding, and asphalt.
