A plurality of injectors of the present invention are connected to a single source of a high-pressure gas to inject an adhesive material into cracks and delaminated sections of a building concurrently. Each injector has a front piece for attaching to a target area. An assembly comprising an inner container containing an adhesive material and an outer container enclosing the inner container is attached to a single cap to make a liquid-tight and gas-tight connection, respectively, and the cap is attached to the back of the front piece to make a liquid-tight connection by means of matchingly tapered surfaces. The inner container is elastic and has a concave bottom surface so that a high-pressure gas introduced into the space between the inner and outer containers can push out the adhesive material efficiently and smoothly from the inner container through the front piece.

A method of injecting an adhesive material into a cracked or delaminated section of a structure comprising the steps of attaching a front piece to a target area, engagingly connecting a deformable bag-like container containing an adhesive material to said front piece, and sending a fluid with an adjustably controlled pressure into an external container which encloses said bag-like container therein and is connected to said front piece in an air-tight manner so as to apply said pressure uniformly to said bag-like container, to compress said bag-like container and to inject said adhesive material out of said bag-like container through said front piece.
