About Us

Based in Houma, Louisiana, Submar started over 30 years ago as a company that provided articulated concrete mats to the offshore oil and gas market for use in the Gulf of Mexico. Since then, we’ve evolved into the industry standard for offshore and onshore pipeline exposure remediation.

Submar has completed projects across the country for most of the major pipeline companies and has provided hundreds of onshore solutions for commercial, civil, and governmental entities, including the U.S. Army Corps of Engineers. Our ability to create new products and customized solutions for a variety of markets allows us to serve multiple sectors.

Our commitment to safety and the environment through environmentally-conscious designs makes us the right company for your erosion control needs. We provide comprehensive, turnkey project management services—from initial site studies to regulatory compliance and post-construction monitoring. Our extensive experience and the broad application of our product suite is the secret to our unique ability to identify pipeline erosion control problems and design, construct, and monitor custom erosion control solutions.
