Depending on your countertop material/color, they may use a matching glue, or may grind some dust from the underside somewhere to mix with the very top part of the adhesive to get a surface color match).
Not too noticeable since it is in the corner and blends well, but we are concerned about any additional problems it might cause. My husband also realized that there is no plywood support underneath the countertops, which really raises more concern for us at this.
If it's a hairline crack with minimal lip, it likely won't get worse or cause any future problem.
No separation or space exists. It's a crack that hasn't actually cracked or split. Fissures occur across the slab. not just in one or two spots. Fissures are level, feel smooth and do not have an edge.
I don't think the supposed "lack" of support had anything to do with the cracked granite. A plywood substrate is sometimes used to create a level surface when cabinets/floors are not level. Or to elevate the kitchen countertop when a laminated edge is used, which.
Fissures can be short or long. wide or narrow. only in the surface or full thickness. or may run through the countertop edges. Many granite countertop colors don't have any fissures, others just a few and some patterns have many running all over.
If it was an edge or in an obviously visible area, then it may have to be redone. But it can likely be repaired reasonably well, and if in a back corner, you simply won't notice it that much (if at all).
Cracks typically occur at sink and cooktop cutouts, edges and corners. Plywood Support for Granite Countertops Most/all granite slab countertops are installed right onto the cabinets without a plywood substrate. This is normal and provides plenty of support.
