New strategic partnership combines ECOncrete’s patented technology with Submar’s proven articulated concrete mats to protect coastlines, pipelines, and offshore assets while supporting marine habitat.

NEW YORK and THIBODAUX, La. , Sept. 22, 2026 /PRNewswire/ — ECOncrete, the leading bio-enhancing marine concrete technology developer, and Submar, an industry leader in design-build erosion control solutions and infrastructure protection, today announced a new strategic partnership focused on bringing more environmentally responsible protection solutions to the Gulf Coast and offshore markets.

Under the new commercial agreement, Submar will manufacture, market, and distribute its signature articulated concrete revetment mats, commonly known as the Submar Mat, incorporating ECOncrete’s patented bio-enhancing technology throughout the Gulf coast and offshore region.

This partnership follows a successful two-year collaboration during which the two companies produced more than 1,000 Mats for multiple marine projects. By integrating ECOncrete’s proven bio-enhancing technology directly into Submar’s widely used concrete mat, the companies are providing a hard-armoring solution that does more than protect infrastructure. The system is designed to help support marine life and local habitat while providing the erosion protection and stability that critical infrastructure requires.

The enhanced Submar Mat – Powered by ECOncrete is designed for a range of applications across the Gulf, including energy, telecommunications, maritime infrastructure, coastal restoration, and shoreline protection. Offshore applications include transmission lines, gas pipelines, subsea cables, and floating and fixed energy assets. Nearshore and coastal applications can serve municipalities, port authorities, waterfront agencies, and contractors working to stabilize and restore shorelines.

“Over the last two years, we’ve had the opportunity to see what this technology can do in real-world projects,” said Joseph Fournet, President of Submar. “As more energy and data infrastructure moves into coastal waters and farther offshore, protecting those assets is becoming more important than ever. We believe we can do that job while also being better stewards of the environment. Bringing Submar’s experience in erosion control together with ECOncrete’s technology gives our customers a practical way to protect their infrastructure and support the surrounding marine environment at the same time.”

“Partnering with established market leaders like Submar is essential to scaling the reach and impact of our breakthrough science,” said Dr. Ido Sella, CEO and Co-Founder of ECOncrete. “Our solutions have been proven for over a decade across 60+ projects globally, in both nearshore and offshore environments. Joining forces with Submar will allow us to quickly meet growing market demand for concrete marine infrastructure that does more than just protect and stabilize. Together we can also minimize impact and deliver nature-positive value for decades.”

With offshore energy development, coastal construction, and restoration work continuing to grow throughout the Gulf region, Submar and ECOncrete are positioned to provide a practical approach to protecting the infrastructure people depend on while also supporting the environment around it.
