Triton® Composite Mattress Systems

 

Whether your design requires the need for underwater placement of a geotextile filter or liner, or you need to cap a deposit of contaminated fill, the Triton® Composite Mattress System is a solution engineers look to.  The Triton® Composite Mattress System was developed to address challenging projects to provide a method to deploy, place and secure geotextile fabric or liner in challenging site conditions, such as, deep water and/or with strong currents. As engineers discover the benefits and design flexibility, the System has been used for many different applications, including in-Situ capping both under water and in the dry.

 

A Triton® Composite Mattress features a geotextile fabric or liner 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.  The controlled mat thickness allows for a controlled cap thickness and does not require the cap to be over designed to assure minimum thickness requirements.  When evaluating Triton® Composite Mattresses, consider some of these benefits:

 

• Design flexibility - The ability to use a project-specific geotextile

• Performance options – Composite 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

• Proven - 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® Composite Mattress Systems have been used in conjunction with the CETCO® Reactive Core Mat®, were deployed as part of a modular reactive capping system for the remediation of Non-Aqueous Phase Liquids (NAPL) contaminated sediments, providing effective capping for a variety of projects. They can also be configured to encapsulate alternative fill materials such as sand, carbon or CETCO Organoclay® materials for site-specific remediation solutions for a wide range of in situ capping applications.  Some of the benefits of Triton® Composite Mattresses are:

 

• 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
