Built on
South Texas
For over two decades, Diamond Eight Industries has been delivering heavy civil construction across South Texas — on time, on budget, and self-performed by our own crews.
Two Decades of
Heavy Civil Work
Diamond Eight Industries was founded in 2003 with a simple mission: deliver heavy civil construction the right way — with the right equipment, the right people, and a commitment to finishing what we start.
From our base in Santa Rosa, Texas, we've grown into one of South Texas's most trusted heavy civil contractors. We've built roads, installed utilities, graded subdivisions, and demolished structures across the Rio Grande Valley and beyond.
We're TxDOT certified, bonded and insured, and proud to have completed over 200 public sector projects for counties, municipalities, and state agencies throughout Texas.
Our equipment. Our crews.
Our accountability.
