ABSTRACT:
The pressure to the cracks in the concrete building and the like exerted by a binding material supplied thereinto is buffered by the expansion of a pressure buffering portion located somewhere between the supply pump and the supply pipe and after the supply pump is disconnected, the binding material supplying operation is succeeded by the pressure buffering portion which, having therein reserved the binding material by expansion, forces the binding material out into the cracks by contraction.
