Fluid mortar or like cementitious material pumped into cavity to fill same and expand fabric walls against tensional restraint of fixedly maintained matrix means. Pressure of fluid material continued against restraint of matrix means until small proportions of fluid material oozes into the porous fabric, and indicates attainment of lowered water-cement ratio in formed body, and then fluid material is allowed to set and harden in said given formed shape. Some, if not all, forms of the invention are particularly useful for under-water installations, such as breakwaters because forming matrices thereof are capable of withstanding rough seas or storm waves without damage during the construction processes, and because the fluid cement mortar pumping operations are possible in minimum of time when rough water conditions subside.，下面是Method for producing sub-aqueous and other cast-in-place concrete structures in situ专利的具体信息内容。
