We have been doing long crack repair since 1987 without drilling the end of the crack. The secret is to force the end of the crack to the surface with a crack expander from the inside. Once the end of the crack is in the shape of a point, start filling the crack 1/4" from the tip. Once the tip is filled, fill the rest of the crack normally to its origin. Very simple and effective. Plus the repair looks better because there is no drill mark at the end. Our crack resin is of a thick viscosity and holds up for years. That's our story and we're sticking to it.
