Submar, Inc. introduced concrete mat technology to the Gulf of Mexico in 1990. Before that time, pipeline operators in the Gulf used traditional sand/cement bags for pipeline crossings. Since Submar's mat technology introduction, sand/cement bag pipeline crossings have become rare. Submar mats have been used successfully for pipeline separation, stabilization and protection. Articulating concrete mat crossings are accepted as the new standard by DOT, MMS, contractors and pipeline operators. The concrete mat is superior in construction quality, cost savings and worker safety.

For over two decades, Submar has achieved success in the offshore oil and gas market by providing an environmentally and technically superior product. The combination of consistent manufacturing, outstanding technical support and 24-hour customer service is the Nature of Submar.
