Details

Tube Lengths.
Rapidobat is supplied to site ready prepared to the lengths you require.

Disposable Formwork for Concrete Columns.
Rapidobat is a high quality, purpose made, spirally wound rigid paper tube. They are fast and economical to use and provide an optimum solution for producing fair finish concrete columns.

The tube is internally lined with a smooth faced plastic release sheet which provides the ultimate in concrete surface finish and appearance. Rapidobat is the fast and economical solution to the problems of forming round columns which is complicated with timber formwork and expensive with GRP of steel formwork. Rapidobat incorporates a unique and patented tear off strip which means that stripping is achieved in a matter of seconds, without any risk of damage to the concrete face. Importantly, after column inspection, the stripped Rapidobat tube then provides physical protection from potential site damage to attractive newly cast column.

Variations

Lined – A PVC liner is fitted internally, which provides a high class concrete finish. There will be a hairline seam on the concrete column formed at the point where the liner butt joins.

Unlined – For applications where surface finish is not critical such as pile caps, tiled columns etc. Rapidobat can be supplied without a fitted liner. When a column is poured like this the negative effect of the spirally wound tube will be transferred to the concrete face.

Square – Using a traditional circular former and polystyrene inserts. Rapidobat can be supplied to produce square or rectangular columns. These formers are supplied with ready chamfered corners and coated boards for high grade concrete columns.

Concrete Pouring Guide.

Tube Diameter	Metres Per Hour
100 – 300mm Diameter	6 mtrs per hour
300 – 450mm Diameter	5 mtrs per hour
450 – 600mm Diameter	3.5 mtrs per hour
600 – 1000mm Diameter	2.5 mtrs per hour

Up to 4mtr high and/or up to 450mm diameter, normal pouring methods (skip or bucket) can be used. Over 4mtrs high and/or 450mm diameter, place concrete by pump and hose.

Place concrete slowly to eliminate air entrapment between tube and liner. Only vibrate from inside the tube.
