Pad Preparation

It is the customer’s responsibility to prepare a level pad of sand or crusher dust. The pad needs to be 150mm deep at the specified diameter.

Rhino Water Tanks provides detailed pad specifications to all customers to assist them in achieving an excellent quality pad. In some areas Rhino can recommend contractors who have previously prepared quality pads for our tanks.

In some circumstances, your tank may need to be installed on a concrete ring beam instead of sand or crusher dust. If your tank is to have an outlet larger than 100mm or if it is higher than the standard height of 2.2m then it is a requirement for a concrete ring beam to be provided. Rhino will provide the customer with all relevant specifications for these concrete ring beams upon request.

Finishing - Pad

Once the tank has been installed the customer is required to place an exclusion zone of a minimum of 10mm Blue Metal/coarse aggregate (no clay or concrete) around the base of the tank after installation to prevent erosion and deter rodents from digging around the base.

Finishing - Water


Once the tank has been installed the customer is required to add water to approximately 10% of the tank volume to allow the tank liner to settle in position.
