Stronghold Preservation was contacted to inspect 2 no. reinforced concrete lift pits, which were both suffering from damp and water leakage. It was found that the kicker joints in both lift pits were leaking. Stronghold Preservation suggested that a concrete crack resin injection system be used to reinstate the basement waterproofing; a resin was injected under pressure into the walls and floor, to effectively seal the joints, and prevent water seepage.


  • Lift pit waterproofing was required to prevent water leaking into the lift pit. The technician is drilling to allow for crack injection of a resin sealant, at Bangor, Co. Down, Northern Ireland 
  • Lift pit water sealing: note free-flowing water evident on lift pit floor. Packers have been inserted, ready for resin to be injected in to seal the leaks at kicker joints, at Bangor, Co. Down, Northern Ireland 
  • The floor of the lift pit; note the water / damp on the floor. The packers have been inserted, ready for the resin injection concrete repair, to seal the leaks at the kicker joints, at Bangor, Co. Down, NI 
  • The resin is being injected into the packers, sealing the leaks in the lift pit kicker joints, at Bangor, Co. Down, Northern Ireland

Further Information


Holes were drilled adjacent to the cracks, and injection packers placed, so that the packers would intersect the mid-point of the crack. The drill holes were flushed out with air to remove dust, and the resin injected in. Our operatives knew that enough resin had been injected when the resin flow was continuous, with no air bubbles. The procedure was carried out at weekends, to prevent disturbance to the staff in the building, and was successfully completed within 5 days.
