ABSTRACT:
A method of constructing a barrier upon an underwater surface by storing sheet material as a rolled web, unrolling the web, continuously forming the web into a longitudinal hollow of a tube-like configuration, progressively positioning spaced longitudinal slot-defining edge portions defining the underside of the longitudinal hollow upon an underwater surface, thereafter delivering ballast material through and between the spaced edge portions into the longitudinal hollow and into overlying relationship upon the edge portions to hold the edge portions upon the underwater surface, and the ballast material being delivered through a portion of the longitudinal hollow as the web is unrolled but the longitudinal hollow is not yet positioned upon the underwater surface.
