In order to minimise site construction time and reduce formwork costs, the precasting of columns either on site or in a specialist yard can offer a distinct advantage over casting in-situ. A number of moulds of differing shape and size can be set up at a time for batch-casting, hence maximising the use of your ready-mixed concrete supply.

Normally associated with multi-storey building construction where forming the stairs in-situ can be time consuming thereby increasing overall production time on the project.

The stairs can be cast either on edge (as a wall) where the finish to the soffit is paramount or cast flat where the finish to the ends of the stairs in more important i.e. the soffit is to receive a surface treatment at a later date.

One main advantage of casting the stairs in the flat position is that the cast unit can be de-moulded quicker by inverting the cast unit in the mould and then removing the mould, leaving the cast unit in the correct orientation ready for lifting into position when cured.

Due to the high class and consistency of finish required, parapet walls on a variety of structures are better precast either on site or in a specialist yard where greater control can be maintained during concreting.

FORM-FAB (Worcs) Ltd. have produced smaller, intricate moulds for a variety of industrial projects where there is a requirement to precast both single items or multiple items (gang casting).

On occasions it is necessary to precast large structural elements and we have produced moulds for use on a variety of major projects including bridges and sports stadia.
