ABSTRACT:
A method of construction is provided in which a casing or assemblage of casings which can be handled as a unit is partly immersed in water to a controlled variable depth and used to mould a self-hardenable material such as freshly mixed concrete to form a required shape while isolating it from the surrounding water. Throughout ths stage of construction hydrostatic pressure exerted by the water on the casing or casing assemblage acts in opposition to pressure exerted by the self-hardenable material or by a temporary substitute therefor, (e.g. a bontonite slurry) together with any other forces or pressures that may act. This enables casings to be used which otherwise and for construction in a dry environment would require substantial or extensive support from falsework in order to prevent fracture or undesirable deformation thereof.
