"When searching for accurate information regarding natural stone countertops the ONLY reliable source is https://www.naturalstoneinstitute.org/  The WORST place to place a seam is directly over a dishwasher." Sarah: Let me direct your attention to the Natural Stone Institute's Detail of Spline Joint Reinforcement drawing 17-D-4 please. Page 14. This is a terrible detail. The last thing you want in a sink seam is a joint that is NOT designed to fail. If the house settles or a top gets out of plane, you want a joint that fails and can be easily remade, not a joint that's going to blow the top of the rail off. Not to mention when Bubba runs out of stainless steel washers and installs one that rusts and blows the countertop apart. As a countertop repairperson with 30 years experience, I have brought this poor detail to their attention to no avail. If you can avoid a seam over a dishwasher, fine, but there is no reason to not make a seam over a modern well-insulated dishwasher. Epoxy a stainless steel cleat under the seam and forget it if it makes you feel better, but I wouldn't bother. The Natural Stone Institute is a fine organization, but they're not Gods. Just men who make mistakes like the rest of us. This sink seam has failed properly. It may have not had the NSI's detail been followed. Would you rather look at this nice do-over or a repaired jagged crack at the end of the cutout or a blowout repair?

Hi All! I have learned sooooo much on this site. Thank you Mr. Corlett. I have had Corian countertops since 1998 with a granite composite under mount sink. Love the Corian, not the sink so much because it seems yellowed since installed. But I do a lot of canning so the sink has put up with a lot of beet juice and boiling hot water with minimal distress, no cracks. Just clean with Soft Scrub and bleach sometimes. We are now building a house. I am again using Corian for the countertops. I am considering either a Corian integrated sink 850 or an LG-HiMacs integrated sink 3118. I do not like the sink drain in the center of the sink as in the 3118 but that sink is an inch and a half longer than the Corian so better for skillet handles to fit in sink. Do you have an opinion as to the staining or cracking or other issue of either product I might consider before making my final decision? Thank you. Cynthia

"My understanding is that any color of Corian can be attached to any color Corian." practigal: You are correct. Corian colors are remarkably consistent throughout the years, so a match shouldn't be too tough. Some Corian vanity bowls are thermoformed from sheets and the heat from the thermoforming alters the color from the sheet it will be attached to. A bevel edge instead of a rounded edge fools the eye fairly well in that situation.

I have a silgranit sink from blanco which is 4 months old and just cracked as well. It cracked in a place (back side 3 inches up from bottom, horizontal crack 5 inches long) which was unlikely to be caused by anything other than a defective product. I am frankly barfing at the people on this forum who are saying the manufacturer is doing all they can/should do by providing a replacement sink. Nobody would want a replacement sink where they already have a poor quality controlled sink from a company, now knowing that they are not the only one. The company should offer a refund and labor install for the replacement. Not saying that they will do that without a fight but that is what they should do. I dont really want to hear from people who think a manufacturer should not do that because no warranty covers that. If a manufacturer is reputable, and not simply trying to cover itself, it will evaluate cases for good will and preservation of its brand name and act accordingly. I have not yet submitted my case either to the store where i bought it or blanco so i dont know if they will react with good will. Also, the idea that a garbage disposal could cause this is ludicrous. This is advertized as strong, and impervious to everyday wear. the store said that the sink was basically indestructible. I have a 400.00 insinkerator disposal which is barely audible and super low vibrations. If a sink cant stand up to that (or any other name brand disposal) then it should not be sold. Update: I am already hearing from the distributor (not the seller - the seller immediately passed the buck to the distributor who i have no agreement with) that Blanco doesnt cover labor, nor will they swap out for a stainless sink (even a Blanco brand). The way i hear this is Blanco has every right to sell you a defective sink for a custom installation and yet have no responsibility for the damage it causes except to ship you another defective sink. This is what i expected. They know that most people wont want to play hardball for what might be under 1k worth of damages. We shall see.
