ETTL's solid reputation for accuracy, dependability, and professionalism is a direct result of the leadership of Douglas Flatt, our founder. Mr. Flatt earned B.S. degrees in Agricultural Engineering and Civil Engineering as well as a M.S. degree in Civil Engineering from Texas A&M University before proudly serving as a First Lieutenant in the U.S. Army Field Artillery Division. After his service, Mr. Flatt joined the Texas Department of Transportation as a senior laboratory engineer and senior resident engineer, specializing in geotechnical and construction materials engineering activities.

At ETTL, our experienced, professionals offer a great variety of geotechnical services throughout Texas and surrounding regions. Since our founding in 1965, we've developed in-depth knowledge of soil and groundwater conditions throughout our region, as well as the specific needs of the local entities we serve who continue to form the infrastructure of Texas. For TxDOT pavement designs, soil samples undergo Texas Triaxial testing to determine its subgrade modulus-one of the strength parameters used in pavement design.

ETTL has carried out construction materials testing (CMT) and construction materials engineering (CME) projects throughout Texas and surrounding regions for more than five decades. Our highly qualified and capable professionals hold some of the most desirable certifications in our region, enabling us to provide critical testing and observation services necessary to bring projects to completion. ETTL participates in several proficiency sample testing programs, including those conducted by AASHTO Materials Reference Laboratory (AMRL); Cement & Concrete Reference Laboratory (CCRL); and TxDOT Materials & Test Division Bituminous Proficiency Sampling.
