ABSTRACT:
Means for repairing or forming structural bodies of self-hardening fluid cement mortar, in a subaqueous or other situs, utilizing a body-forming cavity including body-shaping walls of porous fabric in combination with openwork matrix means fixedly positioned at the situs. The matrix means is received within the body-shaping walls of porous fabric and connected thereto by tension-restraining tie-elements of predetermined length for controlling limited oppositely outward distension of the opposing walls away from the matrix as determined by the length of the tie-elements, upon reception of fluid mortar or like cementitious material within the body-shaping walls to expand the walls thereof to such given shape and size of the body formed by the cementitious material.
