- Easily transported along the West Coast of Africa on barges
- Easily stored by stacking
- Reusable. In some situations, where they have not become an integral part of the environment, the mats can be moved and stored for future use
- Loops on mats allow for easily connecting mats or anchoring
- Individual blocks can be removed, allowing larger vegitation plantings, with compromising the integrity of the mat (talk to us first, please)
- Mat design allows for water to drain through in both directions, reducing hydrostatic pressures
- Can be supplied with Submar's patented Non-Shielding, Non-Abrasive pads
- Ultra violet (UV) stabilized copolymer extruded fiber rope - extremely durable and will not rust
- ASTM rated materials
- Easily installed by Remotely Operated Vehicle (ROV), divers using a handling frame or Submar's patented extreme deep water mechanical handling frame
- Allows for self-silting and adds to the underwater environment (home for undersea wildlife)
- By combining mat thicknesses, can meet requirements for pipe seperation
- Weight keeps pipes or other structures in place and stable
- Grade preparation time and costs are reduced due to the flexible properties of the mats
- In many cases, the mats become an integral part of the environment, blending in and enhancing both the stability of the area and allowing for vegetation to gain a foothold
- We can provide engineering expertise to aide you with your project and work with your team on finding the best Submar Nigeria product for the job
- Geotextile fabrics can be used to further stop soil migration

The Construction Mat is primarily used for separation, stabilization, and protection of underwater pipelines in deep and shallow water or where additional weight or armor is useful in onshore projects. The mat weights 10,500 pounds (4,763kg) dry and is 9 inches (22.85cm) thick.
The design of the mats allows for self-silting and proper separation between the pipelines. The silt-in process aids in the mat's stability. The Construction Mat is easily installed by a ROV (Remote Operated Vehicle), diver handling frame or Submar's patented mechanical handling frame, especially designed for ultra deep-water mattress deployment. Submar mats can be supplied with patented 'Non-Shielding', 'Non-Abrasive' pads.
Articulating concrete mats have been used successfully in the North Sea for many years. Submar introduced concrete mat technology to the Gulf of Mexico (Gulf) in 1990. Before that time, pipeline operators in the Gulf used traditional sand/cement bags for pipeline crossings. Submar mats have been used very successfully for pipeline separation, stabilization and protection. Articulated 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, costs savings, and worker safety compared to sand/cement bag technology.
Access can be gained to pipelines, valves or other protected structures by removing mats used as cover, then replacing the same mats after maintenance. Recent advances in offshore technology have expanded the need and utilization of concrete mats. Mats can be placed diverless by ROV, which allows deepwater deployment. New survey techniques allow accurate placement at great depths. Submar mats have an indefinite lifetime in offshore applications.
