Mould for eight-shaped rainwater tanks

Hydraulically retractable mould for 20000L and 15000L rainwater tanks.

The tanks are poured in their upright position, so they don’t need to be turned upside-down. Due to the 8-form shape, the tanks are only 2500mm wide, so they fit in the normal width of a truck, which brings down the transport cost.

Specifications of the tanks:

• Width 2500m
• Length 4500mm
• Wall thickness tapered 60mm to 80mm
• Floor thickness 90mm
• Covers 80mm or 115mm, depending on the load
• Overall height 20000L tank, including 80mm covers 2510mm
• Total weight 20000L tank, including 80mm covers 9250kg

Specifications of the mould:

• Outside panels to be opened manually by means of a chain drive
• 2 hydraulically retractable inside cores to be taken away by means of a special lifting frame
• Pouring height indicators for the 15000L tanks
• Concrete pump connection
