Leaks Sealed with Hydro Active Foam Injection

A concession area and storage area were damaged as a result of water intrusion through beam pockets on an exterior structural concrete wall.  We asked the contractor to repair the leak to stop further damage and provide advice on how to prevent such occurrences in the future.

Inspection and Repair Method:

Based on an initial investigation of the building, the leak had occurred on the Northwest side where winter storms had accumulated snow, and since the area received little sunlight, the snow melt was unable to proceed.  The gutters were also damaged, and there were overflow signs on the wall above the exterior joint where the intrusion was determined to have occurred. 

Through the use of injection packers placed roughly 4″ away from the joint, 1 2″ holes were drilled at a 45-degree angle back into the joint to address all visible leaks.  A positive refusal of the hydro-active resin was visible both within the beam pocket and along the corrugated metal.  Client was advised to repair damaged gutters and install downspouts to help direct water away from the building in areas where it pooled, as well as to push snow away from the building.
