Federal Capability Statement
Gulf Coast Underground, LLC, is a full service find and fix sewer rehabilitation contractor. Since 2003, GCU has provided honest and dependable, long-term rehabilitation solutions across Florida, Alabama, Mississippi, and Louisiana. In 2014, we are proud to add Tennessee and Georgia to that list. Our firm began as a digging contractor, then evolved into a trenchless contractor performing manhole and wet well rehab. Over the years, GCU has expanded it's services to include: full system SSES, cured-in-place pipe, and main to lateral connection seals. All of our rehabilitation methods have unparalleled track records and are trenchless (no-dig) so as to cause minimal sewer service disruption. From the outset, GCU was built upon relationships and our top priority has been and will continue to be to serve our clients with professionalism, provide them with cost and time saving solutions, and prove ourselves to be a trusted technical resource.
