Cracks in newly installed granite at sink cutout corners
We just had granite installed last week - it is bianco montanha from Arizona Tile - 2cm with 4cm edges. The installer is through my
contractor (not big box places) . It is a very pretty light colored granite. I
do not know how the sink was installed but there seems to be some sort of
horizontal metal bars under the sink attached to the cabinet – it is a not a
HUSH system. Tonight I just noticed that there are hairline cracks at the right
sink corners at the front and back (I didn't notice these last week right after the install) . I have a big rectangular sink cutout but
there is at least 3.25" of granite across each of those areas. I can feel
the unevenness and see it when I look at it from the side. I tried to
photograph it but it just doesn't show well. I don't think the counters were rodded.
The front edge was built up another 2 cm and I never asked the fabricator about
rodding. The sink was plumbed and the back splash tile went in today (not
grouted yet). Of course this is a big long run between 2 other pieces of
granite. The fabricator is coming out tomorrow to look at it - I'm obviously
rather upset.
Above crack at the front of the sink. Pencil & pen points at the crack.
Any idea what could be done? Why would this have happened after the install?

Crack in new Granite Installation
Comments (5)I, too, have a crack in my granite on the front-side of the sink to the front-edge of the granite. They epoxied it and grinded it onsite, but i can feel it and see it if i look closely enough. They made the the 'mistake' of telling me before they repaired it (per the stoneshop owner), so they knocked off $300 from my total cost. An important question to ask is whether or not they reinforced the granite with steel rods in the front and the rear of the sink opening. That will give you a better indication of whether or not the crack could worsen over time or if another area could crack. Also, be sure to have them epoxy it. The glue will keep that seam together long after the rest of the countertop has crumbled ;). One bit of advice my granite guy gave me is that if i ever chip it and can find the chip, superglue it back in and it'll hold without issue. Now finding the chip when you do it is the magic part....See MoreGranite is cracked at my undermount sink!
Comments (5)Hi Many Hats :) What Donna said is true. Get the stone guys out there to find the underlying cause of the cracking. Those cracks should be easily - and virtually invisibly - repairable. Once the guys have solved the underlying problem (normally one of insufficient support) they can fill the cracks with a penetrating glue to bond and stabilize them, grind them down and polish them back out. A capable stone guy should have no problem making the cracks just totally disappear. Check with the stone company to see if they are capable and comfortable doing such repairs. If they are not, have them employ the services of a stone restoration professional to repair the problems to your satisfaction....See MoreHelp ASAP! Granite installed tomorrow - undermount sink question
Comments (8)There are pros & cons for each type of reveal: Positive--where the sink shows/granite is cut slightly larger than sink Pros: easier to clean b/c you can see the gunk and can easily wipe it off (it only gets nasty if you leave it there) Cons: silicone (caulk?) is visible, but if they use clear you won't see it when it dries Negative--where the granite overhangs the sink Pros: You cannot see the gunk buildup or silicone Cons: -- You cannot see the gunk to clean it. -- Dirty water/food can splash up & under where you cannot see to clean it. It's difficult to see underneath w/o leaning way over & into the sink. -- Dishes have been known to break b/c when you lift them out near the edge of the sink they dish hits the stone counter & can break (or, if the dish wins, the counter could chip...but I'm not sure how likely that is). Flush--where the granite & sink are the same Pros: -- easier to clean b/c you can see the gunk -- no platform over or under for the gunk to collect Cons: -- more difficult to do perfectly -- silicone is visible, but if they use clear you won't see it when it dries You will find proponents of all three types of reveals here...but in the end it's what works best for you. Good luck tomorrow!...See MoreSink support for granite installation
Comments (5)there are a lot of ways to mount a sink. the best is with "T-31" mounts. A shaped diamond tool is used to cut "T" slots into the underside of the granite. The sink is then literally bolted in place. you can stand in a sink mounted this way. there are also rail systems available which work OK. the one thing you don't want is a sink that is "glued" in place with the caulking agent between the sink and countertop. We get calls several times a year to repair an installation done by a schlock fabricator where the homeowners sink full of water and dishes fell into the cabinet. it's always a big mess!!...See More

7 years agoThe radius of the corners looks really tight IMHO. My corners are much larger. I am no expert, but could that have anything to do with the cracking of your counter.
