Epoxy won't work. It just going to leak somewhere else. Find the source and fix the pipe.

Just click your link, are you sure the leak cause by the floor? Epoxy is one thing, the waterproofing compound the one doing the job.

If that the case then if you ask professional to do it, they will do water prooffing and test it first before they apply the epoxy.

Because the floor already leak, should remove all the tile for water proof, then only the epoxy can be apply. So the epoxy is just a replacement for the tiles. Effectiveness for the leakage is depend on the water prooffing process itself. If no leakage maybe the epoxy can be apply straight away on the tiles. Epoxy can water proof but they are also prone to crack that can lead to leakage in future. I'm not an expert on this, just my general understanding of epoxy.
