The client had an issue with the threshold between the two rooms where the heating plate had sunk and chipped the edges of the concrete, making the forklifts going in and out of the rooms a very jarring ride. The difficult part was one room was -23 degrees and the other -5 degrees.
Part of the difficulties is that at 5 degrees epoxies stop curing, so we did some tests with a specialized resin which would normally cure in less than 4 hours at 20 degrees. In a small area, we did the test at the -23 and after more than 14 hours it was cured, with this time it gave us the opportunity to do the repairs on a Saturday and the full Sunday for it to dry.
We have other products that can do this but costs were also brought into it.
