FLOATING STRUCTURES WITH

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.
