Integrated Testing and Engineering Company (InTEC) was established in 1991 by Dr. "Paul" Palaniappan, PhD, PE, in San Antonio, Texas. Initially, InTEC provided engineering services in geotechnical engineering and construction materials testing in the San Antonio area. Dr. Paul later broadened the service offerings to include environmental assessment services and serving clients in Austin, Dallas, and Houston.

InTEC has taken steps to enhance our ability to serve our customers and their projects. InTEC has expanded its capabilities by acquiring in-house drilling capability and obtaining accreditation from the American Association of State Highway & Transportation Officials (AASHTO) for our testing laboratory.
