Strapping • Use only Fluid Containment fiberglass anchor straps. • Place anchor straps between the arrows (►4) on the tank sides over each designated rib location. • Use anchor straps specifically designated for each diameter of tank. Curvature of strap matches each tank diameter. • Properly space anchor points: ❑ The proper distance between anchor points is: • Tank diameter plus one deadman width for con- crete deadmen. • Tank diameter plus 12" to 24" for concrete anchor pad. ❑ Place anchor points on both sides of tank. ❑ Anchor points must be aligned with designated ribs (►4) ±I u . • For double-wall tanks, ❑ Anchor straps must be placed in the strap guides on each designated rib (1-4). • For single-wall tanks, ❑ Anchor straps must be placed on top of each designated rib (b-4).

Straps should be snug, but not cause tank deflection. • Measure tank deflection by measuring tank diameter be- fore and after snugging straps. • Use standard nonmetallic gauge stick. • See Installation Checklist for specific measurement in- structions. • Triple clamp wire rope. • If deflection occurs, loosen straps to allow tank to go back into round. Note: Do not use straps between ribs! (Exception 4' diameter tanks.) Concrete Anchor Pad The weight of the overburden on the concrete pad and tank provides anchoring force. The anchor pad information pro- vided below is strictly for buoyancy: • Anchor Pad should be at least 8" thick, with 96 rebar at 12" on center each way. • Poor soil conditions may require increased reinforcement and anchor pad thickness.

The maximum bedding is 24". • Attach anchor points to the ends of anchor straps with turnbuckles or wire rope. • Ref6r to Anchoring Hardware Section for hardware in- formation. • Triple clamp wire rope. Deadman Anchors • The weight of the overburden on top of the deadman and tank provides the anchoring force. • Deadmen are made with reinforced concrete (2-46 rebars centered vertically).
