Beach Prisms Erosion Control
Beach PrismsTM were developed in the 1980's to solve coastal erosion issues in the Chesapeake Bay. Over the past 30 years, Beach Prisms have proven themselves in multiple locations on the Chesapeake and across North America as an economical solution for saving existing shorelines and in many cases redepositing eroded sand.
Each Beach Prism is made of high strength precast concrete and measures 4 ft. tall by 10 ft. long (larger sizes are available). Its triangular slotted design provides stability, durability, and withstands major storms and floods. Perfect for erosion control.
The open design allows water to flow through the Prisms dissipating the wave energy, allowing the sand in the wave to accumulate while reducing the impact on the shoreline. This "soft approach" allows for natural movement of water, plant and animal life, as opposed to the more disruptive "hard approach" of stone breakwaters and seawalls. Permits for Beach Prisms™ installations are issued by state and federal agencies, such as the Department of Natural Resources and the Army Corps of Engineers.
Beach Prisms™, in some cases, have been proven to reclaim lost shoreline, by accumulating sand in front of and behind the Prisms. Results will vary based on many factors unique to each site, including tides, prevailing winds, fetch and availability of sand in the waves. Beach Prisms™ are designed for river and bay front properties.
