Quality Assurance of Deep Foundations has been a significant part of testlabinc’s history. In the late 1980s testlabinc, then Williams and Associates, acquired one of the first commercial dynamic pile testing systems. Today, testlabinc performs a variety of services including non-destructive tests to evaluate deep foundations, such as dynamic pile testing, cross-hole sonic logging (CSL), sonic-echo tests, and shaft inspection device (SID). testlabinc is also adept at destructive tests, including cores of structural slabs, pavements, and drilled shafts. Our firm is experienced in developing and executing quality control programs, customizing tools including software, to ensure the utmost quality and best data management practices.
