摘要

An exemplary injection hose device (10) of the invention permits the structural joints of buildings and other civil engineering structures to be sealed, and is designed to remain permanently embedded in the mortar or cementitious matter forming the joint. An exemplary device (10) comprises an inner tube member (11) having an openable resin port (19), such as a rupturable groove (19) or a plurality of slits (40, 42), and at least one longitudinally extending flap member (13, 14) for protecting the openable resin port (19) and defining, between the flap and the tube member, a space (15, 16) communicating with the openable resin port. An exemplary method of making the device is also disclosed.
