Mr. Tater is the Owner and President of TSI Laboratories, Inc., he has more than 40 years of experience in construction materials testing. His first experience in the industry when he was still in high school. He worked in the lab at Trinity Testing Laboratories where his father worked and was a shareholder. He also worked at Wells Wright Concrete performing quality control tests and calculating concrete mix designs. After high school Mr. Tater and his father started a small concrete company themselves where he performed bathing operations, preparing, and casting precast products.  This only lasted for a few months, in 1983 Mr. BJ Tater along with a partner started a construction materials testing business called Trinity Soils Investigation.  Mr. Tater started as a field technician, then a lab technician and then finally as the Project Manager for the large Industrial Projects such as DOW Chemicals, Union Carbide and Formosa Plastics in Texas and in Louisiana as well as school projects all across the state of Texas.  In 1994 after his father’s semi-retirement, Mr. Tater began to run the entire operation.  In 2004 the name of the company was officially changed to TSI Laboratories, Inc.

Mr. Tater and TSI have played a major role in the City of Victoria’s conversion from asphalt streets to concrete streets. He was aggressively involved in the preliminary design of the project as well as the testing performed for the duration of the project.  The pavement section evolved from using a recycled treated base which required extensive laboratory tests. He has participated in a variety of research projects focused on implementing new sources for flexible base material.  One of these projects was with Inland Environmental which manufactured a base material out of oil field bi-products, and another was with LA Ash which manufactured a fluidized bed-ash, a bi-product of Formosa Plastics.

Mr. Tater has worked with the International Boundary Water Commission (IBWC) on multiple flood control projects in the Rio Grande Valley as wells as numerous dam rehabilitation projects for NRCS, San Antonio River Authority, the Lavaca Navidad River Authority, and many others.
