Formwork ~ concrete retaining walls can be cast in one of three
ways † full height; climbing (page 256) or against earth face (page
257).
Full Height Casting ~ this can be carried out if the wall is to be
cast as a freestanding wall and allowed to cure and gain strength
before the earth to be retained is backfilled behind the wall.
Considerations are the height of the wall, anticipated pressure of
wet concrete, any strutting requirements and the availability of
suitable materials to fabricate the formwork. As with all types
of formwork a traditional timber format or a patent system using
steel forms could be used.
