I redid my shower with Starlike EVO grout. It's a corner stall shower with tile on two walls, a shower enclosure on the other two, and a fiberglass pan with two weep holes.
The shower is leaking on only one side, through the floor into the room below. I've tried using silicone along the bottom edge of the tile, where it meets the pan - plugging and un plugging the weep hole. Nothing seems to solve the problem.
Epoxy grout is completely waterproof... how can any water be leaking through?
