ABSTRACT:
A high-pressure packing device for injecting hardenable synthetic resin into cracks in concrete includes a sleeve of plastics to be wedged into a hole drilled in concrete in the region of the crack and an injection needle attached to the sleeve. The outer surface of the sleeve is formed with grooves starting from the front end face of the sleeve and extended axially of the sleeve to permit the synthetic resin injected into the base of the hole through the sleeve to rise along the grooves towards the crack in concrete to seal the crack.
