Coastal Structures

Breakwaters, groins, jetties and other coastal stabilization structures are built to alter the effects of ocean waves, currents and sand movement. These structures are constructed to:

• Reduce shoreline erosion and sand loss

• Protect existing structures

• Redirect flow in rivers and streams

• Provide shelter for harbors

In many cases, jetties, breakwaters and groins have failed prematurely due to underlying foundation issues and/or heavy toe erosion of the structure.

Tensar Triton® Marine Systems have been used extensively over the past two decades to improve the foundation stability of the underlying structure. In the example to the right, a marine mattress is placed on the native soils to provide a stable foundation platform, while also serving as toe protection to the structure.
