Triton® Filter Mattress System

The Triton® Filter Mattress System was developed to address challenging underwater installations, providing a method to deploy, place and secure geotextile fabric in deep water and/or strong currents. A Triton Filter Mattress features a geotextile fabric encapsulated within or attached to the bottom of a stone-filled mattress made of Tensar® Geogrid. The stone fill provides ballast weight for the fabric as well as a bedding layer for additional riprap or armor stone.

Triton Filter Mattress features include:                                   

  • Design flexibility - The ability to use a project-specific geotextile
  • Performance options – Filter mattress thickness can be optimized to the level of performance required for the project (thinner mattresses reduce excavation and disposal costs as well as installation time)
  • Installation flexibility - A variety of handling and installation techniques
  • Tested for hydraulic stability at Colorado State University, the Triton Filter Mattress meets the challenges of effective overtopping and scour protection in difficult inland and coastal installation conditions.

Triton Filter Mattresses are also used for in situ capping of contaminated sediment. In addition to erosion control, Triton Filter Mattresses address industry concerns regarding:

  • Potential for re-suspension of contaminants
  • Erodibility of capping material
  • Constructability, including uniform cap thickness and over-design of the capping layer to compensate for loss during construction
  • Maintenance concerns, including cost and accessibility
  • Overall durability of capping materials
