Containment
floating booms are made of two-layered rubber / polyester fabric. Each
boom consists of the following parts: freeboard part is a tube filled
with air or polyurethane foam; the draft part is the underwater part
weighted down with a galvanized steel chain as ballast.
The
Rigid containment floating booms have equally spaced vertical plastic
tubes that contain sufficient amount of ballast to maintain upright
position in the water.
