Construction Materials Testing

A structure is only as sound as its individual materials. DDS performs testing and inspection of those materials both in the field and laboratory to verify that they meet the project specifications.  The staff at DDS is comprised of certified technicians and inspectors experienced in earthwork, paving, foundations, concrete, masonry, and steel construction.  Our experienced staff is certified in various fields by the American Concrete Institute (ACI), International Code Council (ICC), Kentucky Transportation Cabinet (KYTC), and Troxler.


The 1,400 square foot geotechnical and construction materials laboratory at DDS is equipped to perform numerous soils, rock, concrete, masonry, aggregate, and asphalt testing procedures.  Tests are performed in general accordance to applicable ASTM or AASTHTO standard test methods.   Our laboratory has been certified by the Kentucky Transportation Cabinet Laboratory Qualification Program to perform concrete acceptance testing services on KYTC projects.


Additionally, DDS’ laboratory has received accreditation through the AASHTO Accreditation Program (AAP), as well as validation through the United States Army Corps of Engineers (USACE) Validation Process - read more about it here.


DDS is a member firm of ACI and KRMCA.
