摘要:
A device is disclosed which fastens and retains a bonding and sealing device in a drilled hole in construction parts or in buildings by forcing injection material, such as snythetic resins into cracks and flaws present on the construction parts or on the building component. A sealing bushing encases a portion of a sleeve. The sleeve is expanded from its inside thereby sealingly clamping the sealing bushing between the walls of the drilled hole and the encased portion of the sleeve.
