Problem

The Spectacle Island Landfill right outside of Boston, MA had been closed for several years before it was officially sealed. When the city of Boston started their Central Artery/Third Harbor Tunnel Project, the sent their leftover dirt and clay to the island to resurface and seal the landfill. Once completed, a new issue popped up along the upper slopes. Storm surge from the Boston Harbor would cause wave run up onto the slopes causing erosion. They needed a solution that would be cost-effective as the cost of barging material to the island was already high.

Solution

PYRAMAT® High Performance Turf Reinforcement Mat (HPTRM) was chosen as it would provide permanent erosion protection of the slopes. PYRAMAT is also a lighter material making it less expensive than a more traditional interlocking block system.

Performance

PYRAMAT was installed along the slopes and then covered with top soil to promote vegetation. The slope was successfully protected from storm surge erosion and covered in vegetation to provide an aesthetically pleasing look.
