What is a seawall?

A seawall is an engineered improvement to the shoreline that creates a barrier between both land and water to prevent erosion and soill loss caused by the active fluid movement of waters by tidal changes, surfs, and storms. It is typically comprised of a structurally reinforced wall, reinforced concrete anchors and tie-backs, and a reinforced cap that secures the tie-backs to the seawall. In most cases, the current majority of seawalls on the waterfront have reached their maximum life expectancy and are on the verge of failing or deteriorating due to the extreme conditions caused by the corrosive nature of saltwater, marine-borne organisms, and storms that take a toll on the waterfront community.

Our Vision = Quality

Our Mission = Commitment


"A commitment to Quality." We strive to provide our clients with the best quality solution by suggesting cost effective measures for their seawall while providing the insight to the construction issues that may affect their project without cutting corners or costs. With this in mind, our clients are ultimately assured they'll be receiving a quality product.

Our History

Since the 1940s, our reputation in building seawalls has been at the forefront of the industry in Pinellas County. It wasn't until 1977 that Gulf Coast Marine Construction was incorporated, making it part of a second generation marine contractor. Over thirty years later and still in the family, GCMC is now a 4th generation family marine contracting firm specializing in the construction of seawalls. We consider every project as an opportunity to reinforce our excellent reputation for thorough planning, accurate budgets and an outstanding safety record.
