The engineered design of the Submar construction mat allows for self-silting and proper separation between the pipelines while increasing stability. The construction mat is easily installed using one of Submar’s patented single, dual or triple mechanical handling frames especially designed for shallow to deep-water mattress deployment.

The manufacturing of a Submar Mat is done in a controlled environment, which allows for year-round production. This mat is durable and can withstand sunlight, extreme temperatures, saltwater and have indefinite life underwater. The mat, being flexible on two planes, will conform to any structure or terrain.
Patented Non-Shielding / Non-Abrasive Padding
Submar’s porous pads will not effect or shield off a Cathotic Protection System. These pads were developed especially to protect thin-filmed, epoxy coated pipelines from coming in contact with Submar’s concrete mats. The pads are 7.5" x 7.5" square and are made of heavy duty, 3/8" P.V.C.  Click here for additional information.
Shipping
Submar mats are transportable by truck and barge. Submar's headquarters, located on the Intracoastal Waterway in Houma, Louisiana, has 300 feet of steel bulkhead docking space with 14 foot draft.
Installation
The construction mat is easily installed by a diver handling frame or Submar's patented mechanical handling frame especialy designed for deep-water mat deployment.
