The YFWB Model 2001XL is comprised of an external shell of extremely durable 8mm polyethylene plastic. The interior of the barrier unit is fitted with a longitudinal structural steel strength member with a shackle connection or attachment point at each end. The strength member provides the longitudinal or tensile strength for the purpose of connecting units together. The strength member also has two sleeves that extend upward through the main cavity to the top of the unit. These sleeves are designed to accommodate options such as lifting eyes, fencing, and sign posting. The tension member also has steel bars that extend downward through the lower cavity of the unit to the concrete ballast insuring that the internal structure remains securely intact. The internal ballast, which is positioned in the lower portion of the unit cavity, has been designed to ensure that the unit will remain stable and vertical under normal current, wave, and wind conditions. The remaining interior void space of the unit is filled with polyurethane (floatation) foam. Galvanized safety shackles are used to connect the waterfront barrier units together.
All Yodock waterfront floating security barriers have gone through a series of rigorous structural, corrosion, and survival tests in the laboratory and during field tests in high energy and environmentally harsh locations.
