In my shower, a flexible sealing strip (like bath seal) sits atop the tray, and the last row of tiles are tiled down onto it. The tray was siliconed to the wall before anything else was done.
I get a leak at one side, seemingly behind the enclosure U-channel, but this area is well-sealed. I've already had the enclosure completely off once so that the inside of the U-channel can be sealed against the tray and wall. I'm ruling the enclosure out, and suspect the fault lies either in the tiles, or the flexible sealing strip. I've already re-grouted the bottom half of the walls and it can't be a coincidence that the sealing strip also ends where the leak appears!
I suspect that the flexible sealing strip is letting water through where the rubberised lip meets the tray. From there, water is effectively trapped and runs to the end of the strip and behind the adjacent tiles (or seeps into the wall behind). Does this sound plausible?
A few months ago I covered the top and bottom of the strip with silicone, which seemed to stop the leak. It doesn't seem like a long-term bodge though, because I'm not sure the silicone sticks properly to the seal and it's now leaking again.
I'm wondering what solutions there are to this?
Do I just cut the flexible strip off with a Stanley knife and fill with silicone?
Or get a uPVC quadrant (like window trim) and attach that over the top with silicone top and bottom?
Or rip the whole lot out and start again?
Seriously at my wit's end with it because every time it seems to be solved, it isn't. Am I worrying about this too much? It's not a huge amount of water, and the walls are blockwork with a solid concrete floor. But having a known leak doesn't sit right with me.
