As climate change and subsidence begin to endanger America’s coastal communities, city and state governments are struggling to stand their ground as it literally sinks below them. Attempts to tame our shorelines often have unexpected or unintended results, sometimes doing more harm than good.
Our webinar, "Geosynthetic Solutions for Coastal Engineering Applications" will discuss various solutions for saving our shores from erosion and compare their advantages and disadvantages. Simply click the video to get started. Those who complete the webinar are eligible for 1 PDH credit.
Flexible and resilient, Tensar's Triton Marine Mattresses adapt to the most difficult conditions, provide durable solutions that reduce costs, and resist scour far better than rigid systems. And because they feature Tensar UX Geogrids, they resist all naturally occurring forms of chemical, biological and environmental degradation – from saltwater to industrial runoff to contaminated sediments. That’s why they’re often specified for aggressive site conditions where other types of materials would rapidly deteriorate. Download project details here.
Construction and protection projects along eroding coastal areas and waterways are among the most challenging to undertake. Irregular land contours, variable subgrades, continuous scour and a variety of harsh conditions can make any project increasingly difficult to stage and execute.
A polymeric marine mattress or “gabion mat” is a cage structure composed of strong yet flexible Tensar® Geogrid filled with aggregate. The mattresses are placed perpendicular to the shoreline and contour to it in a way that creates a gradual transition which dampens wave energy before it hits the shore.
The NJDOT evaluated several scour protection methods as part of the Manahawkin Bay Bridge project including marine mattresses, articulated concrete block mattresses, A-jacks and riprap. Each method was rated on a scale of 1 - 5 (where a score of 5 indicates optimal performance) in various areas such as "constructability," "future maintenance," and "environmental impact." This chart summarizes the scores for each type of scour protection.
The analysis concluded that Tensar's Triton Marine Mattress proved to offer the most ideal solution. It had the thinnest profile and required minimal bed preparation prior to installation. Its size also created a large, stable and protective mass during scour events. Learn about the Manahawkin project and the analysis here.
A Triton® Marine Mattress is an engineered structure made from Tensar Uniaxial Geogrid that's filled with stone. These mattresses were developed for erosion control and submerged foundation applications, including:
Triton Marine Mattresses are available in various styles and thickness options to meet specific project requirements. Increased hydraulic performance and constructability advantages mean Triton Systems can be significantly less expensive than conventional solutions such as riprap. Learn more in our eBook below.

Triton Marine Mattresses have been used on coastal erosion projects across the country, withstanding some of Mother Nature's harshest conditions. Here are just a few examples that prove their long-term performance.
Triton Mattresses were the preferred option for this major bridge project in New Jersey.
