Major leaking in pedestrian tunnel

Problem

Oxford Properties was experiencing major leaking in the pedestrian tunnel walls and ceiling connecting two multi-residential buildings which resulted in closure of the tunnel for safety reasons.

The challenges facing us were:

  • Tunnel was unsafe because of water pooling on the floor.
  • Paint, loose concrete and all contaminants had to be removed from the interior walls and ceiling of the tunnel.
  • Voids were discovered in the foundation walls.

Solution

The tunnel is now back in full operation for tenants and visitors.

Process & Highlights

  • After the surfaces were prepared, a CN2000® mortar (a mix of CN2000B® and sand) was used to fill the voids in the foundation walls.
  • Two coats of CN2000B® were applied on the interior walls and ceiling of the tunnel to repair the cracks.
  • After the application of CN2000B®, a single coat of CN2000C® and CN2000D® were applied to maintain the hydration required for the CN2000B® to cure according to specifications.
