Prep & Completion Requirements

Aqualine tanks are designed for installation on a flat level surface that is able to withstand the weight of a full water tank. To do this the site must be prepared correctly. The correct preparation of your site will ensure that the tank will be trouble free for many years. There are three types of bases for Aqualine Tanks, these being free draining sand, a crusher dust base or a concrete pad base.

NB: If the pad is not prepared properly and the install team arrive and have to wait or come back, the customer will be responsible for any expenses including but not limited to travel, accommodation and wages incurred by Aqualine.

Concrete Base

The concrete slab must be designed to carry the weight of the tank filled with water. Aqualine can provide specific
slab diagrams for basic installations. For more complex installations an engineer may be required.

Sand Or Crusher Dust Base

1. Preparing the Sand or Crusher Dust Pad:
• The sand or crusher dust pad must have a diameter which is more than 2 metres wider than the tank diameter.
• The preferred base material should be free draining and must be free of any sharp objects, clay lumps, stones or material such as roots.
• If crusher dust is used it must have particle sizes of less than 5mm and the tank base must have a Geotextile covering to protect the liner.
• The pad must be stable prior to construction
• The fill must be a minimum depth of 150mm and compacted to a minimum capacity of 50kPa.

2.  It is important that the pad is 100% level.

3. For a tank base cut into a sloping site, make sure there is
adequate drainage to direct water away from the pad.

4. A retaining wall may be required on sloping sites.


NB: The cubic metres of base material is for a flat site with a minimum of 150mm. Base preparation guidelines are designed for stable soils. Customers should consult their engineer on specific base and slab specifications. Tanks located in cyclonic regions will require a concrete ring beam.

Day Of Installation

• If the fitting and strainer locations have not been specified, then someone will need to be on-site to instruct the installers on the required locations, this must be finalised prior to truss installation.

• Once the installation has been completed the tank must have 300mm of water supplied by the customer to secure and set the liner. This must happen on the day of installation. If water is not added on the day this can void the warranty.

• A 75mm high by 400mm wide layer of blue metal or aggregate must be placed around the circumference of the tank to prevent erosion when water runs off the roof. If no blue metal or aggregate is placed the warranty will be voided.

• Inspection hatches should be locked to prevent unauthorised entry (customer to provide lock).
