Water Tank Platforms: Guidelines

jojo water tankThe following tips/guidelines are provided to assist you or your installer.  These tips must be read/used in conjunction with the JoJo Tanks Guarantee, which is available on all JoJo Tanks in the form of a sticker or in document format.

  • A robust base of at least 2 cm wider than the base of the tank (no polyethylene tank should “hang” over its base)
  • The base must be smooth; no sharp stones or hard objects should be in the concrete mixture on the surface (holes could be pushed through the water tank base when it is filled with water)
  • It is recommended that the concrete base be at least 150mm thick ( a 5 000 litre tank holds 5 tons of water!)
  • Any brick/concrete block type of product used to manufacture the base walls should be allowed to set/dry for at least 36-48 hours before pouring of the concrete slab
  • Rubble or sabunga used to fill in the constructed base must be properly stamped in, using the right tool/compactor/heavy stamper  (human weight is insufficient to compact the rubble/sabunga)
  • The water tank base must be perfectly level (use a spirit level to check!)
  • Should lip-channel or beams be used, ensure that the material is treated with an approved product to prolong its life.  The gaps between the lip-channel or beams should be no larger than 50mm (5 cm)

Water tanks are often bought without much thought given to the very important base.  A 10 000 litre water tank will exert 10 tons of pressure on its base!  Similarly, water tank stands need to be built professionally to withstand the forces of a full water tank.  Sturdy water tank stands can be built from brick and mortar; in this case the internal space can be used as a storage room or laundry room, etc.  Serviceable tank stands can also be jojo tank standbuilt from sturdy, treated poles (usually gum/eucalyptus poles in Mpumalanga and Limpopo).  Steel water tank stands can be custom built to spec or ready-made kits can be purchased and bolted together.  We highly recommend that any steel water tank stands are professionally built and are signed-off by an engineer (a 5 ton 10 ton tank full of water could cause extensive damage if the tank stand failed!).  Water Rhapsody is an authorised JoJo Tank dealer so we can supply a full range of JoJo tanks and tank stands.  JoJo water tank stands are available in the following heights: 1.5m, 3m, 4.5m, 6m & 9m for either 5000 litre water tanks or 10000 litre water tanks.  All JoJo water tank stands are certified by engineers.
