Submar, Inc. is a privately owned corporation with headquarters in Houma, Louisiana. Submar manufactures and installs articulating concrete mats internationally. The company was formed in 1980 and presently has over 40 manufacturing facilities internationally serving the United States, Mexico and Nigeria. Submar articulating concrete mats are now accepted as the standard by DOT, MMS Contractors and pipeline operators for reasons including quality, safety, value and the environment.

Submar entered into the onshore erosion control business in 1997 and has since completed projects in all but a handful of states. Submar’s engineered systems are a dynamic state combining time-tested articulated concrete mat technology and "green" design applications offering our customers a wide variety of erosion control solutions while protecting nature. Submar performs turnkey installation for clients on every type of inland waterway. There are very few design professionals and even fewer design and construction professionals in the United States who perform these river restoration services for pipelines. Submar works closely with many government agencies and municipalities, such as the U.S. Army Corps of Engineers (USACE), in planning and designing river training structures in major waterways.

In 2005, Submar began offering site-specific solutions for coastal restoration and other inland erosion applications related to dams, spillways, channel lining, bridge abutments, boat ramps, retention basins, retaining walls, and outfall protection. Submar has completed projects for Chicago O’Hare Airport, US/Mexico Border Fence for Homeland Security, among many others including DOT, NRCS, FEMA and ASDSO.
