After doing a routine inspection of Google’s commercial kitchen floor off the main kitchen in Gordon House, we found that the pedestals were corroded to possible failure. The make up of the floor was a steel decked tile on which the plywood core was rotten. As well as that, a sheet of 18mm ply was also rotten.
After making this discovery it was clear that the existing floor had to be removed and a new floor needed to be installed to rectify the problem. Due to the nature of the location and the fact the washroom was in daily use, all works had to take place out of usual working hours.
All appliances had to be removed from the room. Once everything had been removed the plumbing had to be disconnected, we were able to strip out the existing floor including the metal deck and metal pedestals down to the concrete deck. A submersible pump was required to pump out holding water.
We would need to use as little timber as possible due to it being a washroom floor it will get wet, and we didn’t want to have a similar rot issue in the future.
The main challenge we faced in this project was the timeframe in which the works needed to take place. The project had to be completed over the course of a week to ensure that the kitchen was fully operational for the following Monday.
This meant that our operatives would start works on a Monday evening and work over the weekend with day and night crews to ensure we were able to hand over the kitchen the following Monday morning to kitchen staff, in a usable manner.
On completion of the project, new pedestals and composite timber joists were fitted and leveled. 18mm waterproof board was installed along with a magnesium board laid perpendicular to 18mm WPM Board.
This gives extra strength and takes any play out of the commercial kitchen floor. Flexible screed was then applied. We then placed down a flexible adhesive and heavy duty nonslip mamroleum floor to finish out the work.
