Anchoring bands

Product information
Anchoring bands prevent an individual tank from groundwater buoyancy and thus serve to fix it in the ground.
Anchors should be concreted in a reinforced concrete foundation slab prior the tank is installed. Upon its setting, steel clamps should be fixed and tightened to anchors.
The tank insulating surface is secured by means of rubber pads placed between such bands and the tank. All steel components are corrosion-protected by hot-dip galvanisation.
A spacing of bands depends on the size and construction of an individual tank (number of manholes, size of chambers). The number of bands depends on the tank size.

  • fast and efficient tank fastening to its foundations
  • easy to mount, a set of anchors is sent by CGH to be mounted on site even prior the tank is delivered
  • the whole system is corrosion-protected by way of galvanisation
Technical details

The anchoring system kit consists of:

  • a steel anchoring system clamp
  • a rubber spacer
  • a threaded rod (M24)
  • an anchor plate (with a hole for a threaded rod)
  • nuts, washers
  • min. 10 mm thick bituminous or other insulation should be applied between the tank and its foundation.
  • A rubber spacer supplied with the band should be applied between the band and the tank.
  • The static-strength calculations concerning tank anchorage were provided based on the following:
    • the water level equals the ground level
    • safety coefficient for water buoyancy – 1.3.
    • unit weight for ground – 18 kN/m3
    • unit weight for concrete (B20) – 22 kN/m3
    • minimum tank location in the excavation – 800 mm
  • Attention: The specified assumptions do not exempt from the obligation to perform adequate calculations on foundation and buoyancy for local soil conditions.
