Beachsaver Reefs |
Beachsaver
reefs are composed of interlocking concrete modules that weigh 21 tons
each. They are specially designed for stability in ocean, bay and lake
environments. Triangular-shaped, each module is 10 feet long along the
shoreline, 6 feet high and 16 feet wide perpendicular to shore (see photo).
A large saw-toothed base and low center of gravity help provide extreme
stability against wave and tidal action. Stability
is enhanced by the mass of the interlocked modules and by a patented ridging
system. The reef's shape and other design features make it extremely stable
in storms. In the University of Delaware wave tank, it took hydraulic jump
wave simulation beyond the limit of natural forces to overturn even one
free-standing reef module. The toe of the reef structure is protected from
scour by the submerged placement and use of stone-filled Triton marine
mattresses (for more information click here to go to our GEO-SYN site).
Beachsaver reefs are built for longevity under the most severe conditions. They are pre-cast from a composite of concrete and Microsilica Force 10,000, a W.R. Grace Construction Products material. The composition has twice the compression strength, 10 times the impact strength and 20 times the salt resistance of conventional cast concrete. It also is superior in resisting freeze-thaw. Steel rebar reinforces the concrete for additional structural integrity. Beachsaver reefs are environmentally friendly. They are made from inert materials which have no negative impact on water quality. In fact, sessile marine organisms such as the blue mussel adhere to and grow profusely in the hollow cavity of the reef. This in turn attracts other forms of marine life from striped bass to harbor porpoises. Breakwaters
