TESTIMONIALS

"I can say without hesitation that I would recommend Gulf Coast Underground’s Spectrashield system to anyone. From their technical support to their installation crews, the GCU team has transformed our thinking and understanding of concrete coating protection for existing and new structures. My clients value workmanship."

Chris Lacroix, PE
Manchac Consulting Group

“We have been doing business with Gulf Coast Underground for almost two years, and the coating system that you offer has reduced our infiltration by about 1.0 million gallons per day. Your company has always gone above and beyond to rehabilitate manholes that we though needed replacement”

Brian Purcell, PE
Gadsden, AL Water Works and Sewer Board

"GCU has been rehabilitating our sewer manholes with SpectraShield for many years now, and they have always done a very professional job. After trying numerous products (including cements and epoxies) to stop exfiltration at my headworks, nothing seemed to work. I gave GCU an opportunity and many years later things are still looking great. I knew that if it (SpectraShield) could handle the movement in the cast-in-place walls of my headworks, it would be able to handle the ground movement in a manhole and permanently seal out infiltration."
