The office rooms, the men’s and women’s bathrooms, and the men’s and women’s locker rooms of the Time Warner Cable Mgt were experiencing water infiltration in the ceiling locations. The waterproofing membrane surrounding the drains in the kitchen and bakery departments above these rooms had been compromised and/or not properly tied in. As a consequence, water was entering into these office spaces below whenever the Whole Foods kitchen floor was being washed.

There were water intrusive cracks, drain penetrations and empty cores within the floor slab of the kitchen. Consequently the water from the washing was penetrating the quarry tile and the mud set, through the compromised membrane, through these water entry points and on top of the ceiling tile. The mechanics accessed the underside of the kitchen’s floor slab by removing the ceiling tile and grid in these rooms below. The drain pipe penetrations and the empty cores were appropriately patched as high-deep as possible with hydraulic cement and / or high strength repair mortar to create a solid substrate. The cracks and these pipe penetrations were then injected and the resulting gel not only occupied the volume of these water entry points full slab depth, but also created a gel seal where the kitchen floor slab membrane was compromised or not tied-in properly.

The frustrations of the office personnel were alleviated, as they no longer had to work in messy water conditions. New ceiling tiles were installed to replace the previously water stained ones, and office operations were no longer disrupted by water penetration from the kitchen above.
