Australian map made of steel Trying to compare rainwater tanks on the market and work out price differences??? Our Australian Aquaplate steel is produced to Australian potable water standards. Some imported steel does not meet standards. Our galvanised steel is Z600, specifically manufactured in Australia for rainwater tanks. Cheaper Z450 galvanised steel is not intended for rainwater tanks. Not all steel tanks are equal in quality.

Installation Guide

Site Preparation

Site preparation is important and all tanks require a stable, flat surface. Rocks in the surface will puncture the base of the tank. Do not use wooden sleepers.

Site Preparation Sample of Good Base Options
Site unsuitable for a tank base. Note uneven surface and presence of rocks A suitable tank base made from dolomite. Pad is larger than the tank's diameter, has been levelled and compacted.

Good Site Preparation Samples
A suitable tank base made from dolomite. Pad is larger than the tank's diameter, has been levelled and compacted.

Pad

A reinforced concrete pad must be level and greater than the diameter of the tank. A pad of dolomite/crusher dust is also suitable, but must be level and compact and, no less than 100mm thick. Again, the diameter of the pad must be greater than the tank.

Concrete slabs or pavers can also be used but they must be level and stable.

Earth-Ring

An earth-ring can be used. For a round, traditional tank we can supply a suitable sized ring. This must be filled with coarse sand or dolomite, and compacted.

Tank Stands

A stand for a round traditional tank must have hardwood decking with gaps no greater than 50mm (2").This is also suitable for ecotanks. Bearers must be strong enough to structurally support decking and prevent sagging when tank is full. The frame of the stand must be engineered to support the weight of the tank when full to capacity. The legs of the stand must be supported by a firm, solid, level base such as a concrete slab or large (i.e. 600mm x 600mm) concrete pavers. Once in place, the tank should be filled with enough water to prevent it blowing off or tied down.

These metal tank stands have been designed for the Ecotank®. Tank stands must be engineered to correctly support the base of a tank when the tank is full to capacity.

Malthoid

Malthoid is black tar matting. We strongly recommend malthoid be placed under all galvanised tanks to protect the base of the tank. We are able to supply malthoid pre-cut to size.
