Maccaferri Polymeric Marine Mattress (PMM) were developed to provide erosion control and scour resistance for submerged applications, such as foundations to breakwaters, groynes or other marine structures.
PMMs are constructed from HDPE punched and extruded geogrids, fabricated into a mattress container. The PMM is filled with appropriate and durable stone fill and then lifted into position in the marine works, using suitable equipment. Benefits of using PMM (Polymeric Marine Mattresses) include:
– Durability and long-term tensile capacity
– Monolithic high mass and porosity
– Flexibility and hydraulic characteristics
– Energy dissipation characteristics
