Engineered Anti-flotation Systems for Underground Fiberglass Storage Tanks
Tanks with inadequate cover and high groundwater conditions can easily become buoyant. Anchoring systems and proper soil back-fill are common ways to offset flotation of underground storage tanks. Fiberglass Tank Solutions offers three options when it comes to anchoring systems. All three of these anti-flotation systems can be provided with structural and buoyancy calculation and P.E. stamps for over 40 States
Concrete Deadman System
As an industry standard, Fiberglass Tank Solutions provides a conventional concrete deadman systems. Concrete has been used for tank anti-flotation systems for over 50 years and is a time proven system. Our concrete deadman systems are engineered for structural strength, have adjustable hook points, and come in a tapered design to easily ship with most tanks up to 10’ in diameter. Concrete deadman systems come complete with anchor points, turnbuckles, and straps to provide a fully integrated anchoring system.
TankAnchor™
TankAnchor ™ is a geocomposite comprised of a coated high strength polyester geogrid bonded to a polyester non-woven geotextile, designed for superior anti-buoyancy resistance for installation of underground storage tanks.
As compared to conventional concrete deadman systems, TankAnchor ™ provides an anti-flotation system with higher safety factors, and shallower bury depths for both single and double tank installations. This anti-flotation method does not require special tools, is manufactured from corrosive resistant material, and is less costly than conventional methods.
· Allow for shallower bury depths
· Less cost
· No special tools needed
· Single or Double tank installations
· P. E. stamped calculations
Fiberglass Deadman System (FDS)
Fiberglass Tank Solutions also provides an engineered fiberglass deadman system (FDS) that is light-weight, easier to handle and ship than concrete, and can usually ride on the same truck, saving freight dollars. This Fiberglass anchoring system installs quickly and uses the soil load over the top of the tank and the soil load above the anchor system to offset buoyancy. The fiberglass deadman anchoring system comes with flexible anchoring points and utilize protruded fiber reinforced plastic straps, galvanized turnbuckles, and anchor points to complete the anchoring system.
