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 very 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 quality of
construction, cost savings, and worker safety.
Submar, Inc. currently has strategically located manufacturing facilities
across the United States (Louisiana,
Illinois, Kentucky, California) and one in Mexico. Submar ships
mats throughout the United States and all around the
world.
Submar manufactures two different
size concrete mats consisting of 160 elements laced with
400 feet of ultra violet stabilize copolymer extruded fiber
rope.
Construction Mats are 8’ X
20’ X 9” and weigh approximately 10,500 lbs. These mats
are used primarily offshore for separation,
stabilization, and protection of pipelines.
Revetment Mats are 8’ X 20’
X 4½” and weigh approximately 6,200 lbs. These mats are
used primarily onshore for pipeline protection,
erosion control, and shoreline stabilization.
The manufacturing of Submar
Concrete Mats is done in a controlled environment, which
allows for year-round production. These mats are
durable, and can withstand sunlight, extreme
temperatures, saltwater and have indefinite life
underwater. The mats, being flexible on two planes, will
basically conform to any structure or terrain.
