ABSTRACT:
A method for injecting a chemical barrier into a surface aperture is provided. The method provides a vacuum to a work site to evacuate the air from the work site. Then, an injector head is located and retained at the work site. The injector head has a gasket that forms a seal around the work site. Pressurized fluid is conveyed to the work site through a first conduit in the injector head. Any unused fluid is conveyed away from the work site by a second conduit in the injector head.
