Hold-Down Straps

Hold-Down Straps

Hold-down straps are made to work in conjunction with adequately sized anchoring to counteract the underground tank’s natural buoyant forces when the water table rises. If a fuel tank must be located below the ground elevation in an area with flood hazards, it must be protected against the forces of buoyancy, velocity flow, and debris impact. Providing adequate anchoring for the tanks is one of the most common methods for protecting underground tanks. A fuel tank located below ground in a flood-prone area can be restrained by a counterweight in order to counteract the buoyancy force that is exerted by saturated soil during a flood. This can typically be either by anchoring to a reinforced concrete pad under the tanks or to deadman anchors on the sides of the tank.

The Ultimate Straps for Underground Storage Tanks

Our hold-down straps are made through pultrusion, which is a continuous process for manufacturing composite materials with a constant cross-section. Reinforcing fibers are pulled through a resin, and into a heated die where the resin undergoes polymerization. This results in fiberglass straps that are lighter than their steel counterparts, last longer, are more durable, resist corrosion, and have a lower coefficient of expansion than steel. The straps are then connected to deep galvanized cast-iron hooks using an exceptional composite-to-metal bonding technique providing an extensive load capacity.
