Stop drill crack
Stop drill crack at both ends. Bevel each side of crack 5 times in width to the thickness of the material, trying not to widen the gap. Cut a thin strip of FG cloth to fill the bevel and wet out the surface and cloth with resin. Add cloth/resin of widening strips until the bevel is filled and extends out past the bevel.Cracks on the shower base and near the door hinges are subject to stress and will probably continue spreading after you patch them. To prevent this, drill a stop-drill hole at each end of the crack using a drill and a 1/4-inch drill bit. You can usually fill 1/4-inch holes with epoxy paste, but to be on the safe side, it's a good idea to lay a small …In this paper, finite element simulations were performed on various plates containing the small center crack at which the stop drilling holes and the additional holes were drilled, and influences of the additional hole on the relaxation effect of the stress concentration of the stop drilling hole were investigated.

Drill a Hole! A hole that is drilled at the end of a crack in the material will stop it from spreading. There is no place for it to restart. It cannot travel any farther because there is not any high-stress area that is weaker than the surrounding surface.
