construction materials testing soil






Construction Materials Testing (CMT) is an important part of Quality Assurance (QA) and Quality Control (QC) in order to maintain compliance with all construction specifications and American Society of Testing Materials (ASTM) standards.   CMT includes but is not limited to soil, aggregate, concrete, masonry, asphalt, and fireproofing. At L.E. Gregg Associates, all samples are tested at our in-house laboratories by our certified soils, aggregate, concrete, and masonry technicians. 


L.E. Gregg’s in-house labs are certified by the Cement and Concrete Reference Laboratory (CCRL) for concrete, concrete masonry units, and aggregate testing

and the AASHTO Re:Source Materials Reference Laboratory for soils and aggregate testing. 


L.E. Gregg is KYTC pre-qualified for Geotechnical, Environmental, and Special Inspections with Construction Materials Testing services. And we are also U.S. Army Corps of Engineers certified for Aggregate, Concrete, Masonry and Soil Testing.

What is the Difference Between

Special Inspections & Materials Testing?


Materials Testing typically is beyond the building foot print (pavements, utilities, etc.) or within the building that are not critical to the integrity of the specific building unless otherwise indicated.
