One option is the Concrete Deadman System, which comes complete with fastening points, clamps, and belts, providing a fully incorporated anchoring system.

Another option is the TankAnchor system by FTS, designed with higher safety aspects and shallower depths for submerging. This system doesn’t require special tools and is constructed from materials resistant to corrosion. It is compatible with both single and double walled tanks and comes with P.E. stamped computations.

Finally, the fiberglass deadman anchoring system offers adaptable anchoring points. It utilizes bulged fiber strengthened plastic straps, invigorated connection screws, and secure sockets, providing a comprehensive anchoring solution.
