Recommendations for preparing the platform of your flexible tank

  • Make sure your level platform area fits the dimensions of your tank and add 500mm to 1000mm extra on all four sides.
  • A flat horizontal surface is very important.  The platform must be levelled with a Laser so the tank will be balanced and not put the fabric under excessive strain.
  • The platform should save 100mm at least of fine pit sand on top and be clean and stable without any rough/sharp material which may damage the tank over time.
  • Make sure your compaction rate is +/-2 tonne/m2 as the platform must be able to support the weight of the tank without causing it to sag or deteriorate.
  • If your compaction rate is not easily achievable LABARONNE, (the tank manufacturer), recommend a 300mm bed of gravel first to ensure the stability of the platform with 100mm of fine sand on top.
  • If using gravel and sand, the use of a Geotech cloth layer is highly recommended between gravel and sand layers to keep them separated.
  • An anti-puncture mat/groundsheet is also an option to place on top of your sand layer and under the tank for extra durability.  These can also be purchased from FlexiBladder Australia.
  • All connections to the tank which are above ground should use flexible hoses with a minimum of 3m in length as this allows the valves to go up and down with the amount of liquid stored in the tank at the time.
