Onshore Mats

Submar revetment mats provide a resilient, eco-friendly solution for pipeline protection and erosion control, blending seamlessly with natural surroundings while maintaining streambed stability and supporting biodiversity.

About Our Onshore Mats

Articulating concrete revetment mats are a cost-effective, long-term solution. These mats, which are also used for pipeline separations and erosion control, consist of flexible concrete elements connected by ultraviolet stabilized copolymer extruded fiber rope.

Submar Revetment Mats

  • The Submar revetment mattress is an articulating concrete mat that is commonly used as protective cover for pipelines in rivers and streams.
  • The concrete mat solution will provide a long-term, continuous system of hard-armor protection for the entire length of the pipeline from high bank to high bank.
  • The mats are considered “engineered riprap” and, in comparison to riprap, will perform better in the bed of the stream where the highest shear stresses occur.
  • The mats have a low hydraulic profile in the streambed at only 4.5-inches thick.
  • The mats can be removed and replaced for maintenance of the pipeline if necessary.
  • The concrete mats will articulate and self-adjust with the streambed to prevent the upstream migration of future head cut erosion.
  • The mats allow for natural vegetation, restoring the look of a natural riparian corridor. The vegetation allows them to blend with the natural surroundings, creating wildlife habitats and increasing biodiversity within the stream.
  • Because the mattress articulates over time and acts as a grade control structure, the hard-armor mat system will hold the current grade and prevent future degradation of the streambed. Grade control structures can provide vertical stability to the local area around the structure and also to the entire channel system, thus having far-reaching, positive impacts.
  • This solution is an alternative to lowering the line: it is more cost-effective, and the construction will result in less overall disturbance.

Offshore Mats

Submar offshore articulating mats provide a durable, low-maintenance solution for protecting pipelines. Their innovative, non-abrasive padding safeguards pipelines, ensuring both long-lasting protection and reduced wear.

About Our OFFshore Mats

Submar’s offshore mats, also known as mud mats, are a BSEE-approved solution for pipeline protection, offering unmatched durability and safety in offshore environments. Designed with non-abrasive, non-shielding pads, they protect thin-film epoxy-coated pipelines from abrasion, outperforming traditional hard-armor methods like riprap and sandbags.

More About Our Mats

  • Submar’s offshore mats, approved by the Bureau of Safety and Environmental Enforcement, meet the highest standards for safety and durability in offshore applications.
  • They offer enhanced pipeline protection with patented, non-abrasive pads that prevent damage to thin-film epoxy-coated pipelines, reducing wear and extending pipeline lifespan.
  • Designed as a more durable alternative to traditional hard-armor methods like riprap and sandbags, Submar mats provide long-lasting stability in harsh offshore environments.
  • Environmentally responsible, Submar mats comply with the Louisiana Department of Natural Resources Coastal Use Permit General Permit 24, supporting sustainable coastal practices.
  • These mats present a cost-effective, low-maintenance solution, significantly reducing the need for frequent upkeep and replacements.
  • With flexible applications across various offshore and coastal protection needs, Submar mats ensure adaptable, reliable protection for a range of project requirements.
  • Easily deployed and adaptable to different site conditions, Submar mats allow for quick installation, minimizing project timelines and reducing operational downtime.
