Tectonus seismic hold downs

Tectonus storage tank hold downs

State of the art devices

The Tectonus tank hold device (RSFD) is a self-centring , damage-free anchorage system that offers superior seismic protections for storage tanks and assets in a range of industries:

  • Wine, Dairy, Petrochemical industries
  • Water & waste water storage tanks
  • Agricultural containers
  • Industrial liquid silos, oil & gas containers

Earthquakes can cause significant damage to tanks during the initial event and further during aftershocks. If sacrificial components or complete replacement is required between events, the tanks are at increased risk.

Advantages that make the difference

No sacrifical parts

Devices are designed to withstand earthquakes and aftershocks without repair or replacement (to specified capacity).

Contrary to yielding anchorage systems, stiffness/strength degradation will not happen in Tectonus hold-downs.

"R" Factor

With exceptional added hysteresis damping for new tanks/silos, any range of R factors is achievable.

For existing tanks/silos, the R factor can be significantly improved by replacing the anchors.

Simple installation

Devices can be installed on new or existing tanks


Existing tanks can be retrofitted with minimum business interruption and without shortening or strengthening of tank wall/barrel.

Performance tested

Each Tectonus device is performance tested to ensure it performs to its required specification.

Lower tank & foundation costs

Tank and foundation costs can be less than usual when choosing to implement the Tectonus hold downs
