The Natural Solution

Wave Attenuation Devices (WAD®s) are designed & engineered to be environmentally sensitive. WAD® Arrays are specifically modeled with characteristics that mimic natural barrier reefs and shore protection. They attract a full array of local species and promote growth on all surfaces of the reef and the surrounding habitat.


Top to Bottom

WAD®s arrays have a comprehensive, life-cycle impact on the entire habitat where they are placed. Attenuating damaging wave action immediately begins shoreline protection and often rebuilding. Sediment movement enhances marine life and vegetation, which then feeds and fortifies even the birds and other wildlife in the surrounding environment.

True Intergration

WAD®s become a part of surrounding wildlife sanctuary. They intercept incoming wave energy before it hits the shoreline, slowing or even stopping erosion altogether. The calm water between islands or beaches and arrays provides foraging and nesting habitat. They keep barrier islands and marshlands intact for pelicans, cormorants, herons, egrets, and spoonbills, among other species.

WAD®s are precast concrete specially formulated to be pH neutral and designed to foster the growth of oysters, barnacles and other sessile organisms to attach immediately, which are food for fish and birds.


WAD®s provide oxygen-rich environment that greatly accelerates marine biomass development. Optimized, hydrodynamic design and the resulting cyclonic flow of micronutrient-rich water produces an “up welling” of rich biomass, creating a food source for the feeding fish, shellfish, and sub-surface plant development.

The acid-neutral concrete structures are hollow with engineered angled cutouts on the slanted sides that allow small fish and crustaceans to enter or pass through and encourage oysters, barnacles, or other marine life to attach, thereby creating a sea life nursery in much the same way naturally-growing mangrove roots and seagrasses do.

Site-specific array configuration promotes schooling of larger species on and around the reef array all contributing to long term diversity and habitat productivity.

MArine Habitat

 WAD® arrays are designed to be an Essential Fish Habitat (EFH). The design and durability of these units deliver exceptional environmental benefits. Our complex systems provide extremely strong marine diversity with an abundance of recreational and commercial marine species.

 WAD®s are methodically designed to promote and accelerate rapid marine growth on all hard substrate surfaces, both inside the structure and out. Promote marine life habitat and engineered to attenuate the damaging impact of wave-driven erosion to protect the world’s shore & coastlines.

(Our Team) gives unanimous support of approval for the WAD®s to be used throughout the entire project. Thanks for resolving the erosion issues for PGS and meeting all our deadlines. It allowed us to bring home one of the ONLY two prestigious Presidential Awards for protecting waters the Continental US and Gulf of Mexico.
The WAD® system, has far exceeded my expectations. It is also a very cost-effective option. This system is not off-the-shelf, but site-specfic, modeled and engineered for the (location) conditions. This system works dramatically. It has protected our properties by preventing further erosion and preventing foundation uindemining. It has increased the Villas’ value through the reclamation of land lost from the original title, and through the stabilization and expansion of the world famous Negril beach fronting the property.
With WAD®s, both shoreline protection and high sediment accretion rates are provided, in one simple package. They can then be easily repositioned further offshore for continued accretion or down the shoreline as an even more cost effective method of rebuilding additional beachfront. Further, these WAD®s can often support large amounts of marine biomass and act as a marine life habitat, further contributing to the recreational appeal and tourism aspects of our beaches and snorkeling barrier reefs.
The Fish Haven®/ Coastal Haven® series modules are methodically designed to promote and accelerate rapid marine growth on all hard substrate surfaces, both inside and outside the structure and specifically engineered to act as wave attenuation devices to protect the world’s coastlines. The hydrodynamic engineered shape of the units and designed openings promote a “designed flow of micronutrient rich water” across all surfaces. Combined with the engineered light access, this leads to unsurpassed biomass development and reef productivity.
This is the only known product that is environmentally sensitive with similar characteristics of a natural barrier reef, attracts a full array of local marine species and promote marine growth on all surfaces of the reef, provides engineered openings to promote designed flow of micronutrient rich water across all surfaces and increase light access to promote the rapid growth of marine life. The design of the reef system provides substantial cover and spawning habitat, contain the geometric and physical material properties similar to a breakwater in order to withstand wave heights and currents associated with a local 20-year storm events, as well as provide a structurally useful minimum 25 year life.
