Soils Services

S.T.A.T.E. Testing services include soils tests for classification or moisture/density control. Our soils lab is approved by IDOT to perform acceptance tests required by the Project Procedures Guide. Field technicians can perform Quality Control and acceptance testing at the jobsite.

Construction Materials Testing - S.T.A.T.E. Testing, LLC

In 1999, we started this company with a plan to provide professional engineering and materials testing services to the highway construction industry and public construction agencies. Since that time, we have grown beyond my wildest dreams.

I credit our growth to our response to the economic and environmental needs of our clients, and to the priorities of the industry at large. Our industry is always changing, and we have changed with it. When we started, "green alleys" had grass growing through them, not water flowing through them. "Ground Tire Rubber" referred to skid marks on the road, not a component of the road. "FRAP" used to be a typo referring to RAP, not a new technology in asphalt design. Concrete mixture technology has evolved from cheap tap beer to a hand-crafted microbrew. All these things have become part of our industry, and we are proud to be a part of it. Again, a hearty "Thank You" to our clients for making our dreams come true.
