Concrete Density
Concrete mattress density is generally between 145-150 pounds per cubic foot.
Under conditions where varied mattress weights are required, we can work with SPS to engineer solutions with various densities.
CONCRETE
Roman Stone concrete mattresses are a proven solution for many of the challenges faced in subsea cable protection—from bridges and ports to offshore wind. They’re also cost-effective and available with multiple delivery options along the Eastern Seaboard.

- Together with SPS, we can design custom mattresses to your specifications
WHICH MATTRESS IS RIGHT FOR YOUR PROJECT?
Fronded Concrete Mattress
- These anti-scour mattresses can be deployed directly into position or attached and deployed with a concrete mattress.
- When attached to a concrete mattress, fronded mattresses provide additional protection and stabilization.
- Our team of engineering experts can help with special requirements, mattress designs or modifications.
Fleximat
- This standard Roman Stone product provides a high degree of flexibility and can follow the contours of a pipeline or cable along the seabed.
- Constructed using high-strength concrete profiled blocks and UV-stabilized polypropylene rope.
- A brick-pattern matrix reduces the open-line effect for additional protection and stability.
- Designed to scour into the seabed for increased stability and security against overtrawling.
Tapered (Wedged) Fleximat
- A fleximat revetment mattress is used for protection against river and sea embankment erosion.
- Flexible construction allows it to accommodate variations in embankment profiles for maximum erosion protection.
- Suitable for many environments, including harbors, docks, lakes, riverbanks, breakwaters, weirs, slipways, outfalls, reclamation and environmental applications, slope stabilizations and roads.
C-Shore (Cast Shore) Logistics
Through our unique C-Shore Logistics™ partnership, we can deliver concrete mattresses along the entire Eastern Seaboard via marine logistics to simplify delivery for your team, reduce costs and minimize the carbon footprint of a project.
CUSTOM SOLUTIONS
Protection Pads
When clients require low-friction or anti-abrasion material between the concrete mattress and the asset that it is stabilizing or protecting, we work with SPS to offer and affix a range of solutions.
Partners in Progress
We license technology through a partnership with Subsea Protection Systems Ltd. (SPS), a worldwide leader in subsea and stabilization products.
