Custom Marine Construction By Marinus

About Us

Marine construction dates back to ancient civilizations that built harbors and seawalls to support trade and travel. Over the centuries, the industry has evolved from using timber and stone to advanced materials like concrete and steel. Today, it combines time-tested techniques with modern technology to build durable, environmentally responsible waterfront structures.

CMC by Marinus specializes in marine construction, including decks, docks, seawalls, and boat lifts, delivering high-quality waterfront structures with expert craftsmanship and a focus on durability. With over 30 years of experience and a proven track record in large seawall projects across South Florida, we pride ourselves on our commitment to quality workmanship and timely execution. As we expand, our new executive team brings extensive expertise from the Oil and Gas industry, allowing us to integrate innovative strategies and enhance our service offerings to solidify our position as a premier provider in the marine construction sector.
