FLOATING STRUCTURES WITH
STYROFOAM
™
BRAND BUOYANCY
BILLETS
These instructions describe the materials
needed and guidelines for building
floating docks, rafts and boat wells/docks
with STYROFOAM
™
Brand Buoyancy
Billets.
Extremely buoyant and durable, the
billet material is composed of millions of
tiny non-interconnecting air cells – each
serving as an independent buoyancy
chamber. These billets won’t lose their
buoyancy, even if punctured. It takes
only 1 cubic foot (0.03 cubic meter) of
STYROFOAM
™
Brand Buoyancy Billets to
float 55 pounds (25 kilograms).
Lightweight, the billets are easy to
install. And they stay on the job year after
year under normal conditions. They resist
the attack of destructive marine growths,
are unaffected by salt or fresh water, won’t
become waterlogged and won’t corrode.
