The amount of information on granite issues is so massive that most subjects cannot be dealt with properly on a single page so follow the highlighted links to more info on the subject. Granite is a natural product whose beauty comes from the porosity, crystalline quartz structure, fissures, movement of the conglomerate mineral composition, veining, and grain. Granite forms as molten magma or sub ducted sedimentary rock, deep within the earth under tremendous heat and pressure. Once polished to a high gloss, the variation of the minerals from slab to slab and the sheer variety of stones available ensures that your countertop is one of a kind. It can have very hard minerals as part of the composition in addition to the quartz content. It is very dense and heavy , making a massive countertop, available in large slab sizes, and varieties are available from all over the world. There is a boom in granite use currently, driven by lower prices caused by import material, a surge in the number of shops fabricating granite due to the ease of fabrication and the high profit margin. Wow, sounds like I sell granite! Yes, I do, but like any material, what makes it good can also make it bad. Being a multi-material shop, we have no reason to avoid talking about the weak points of countertop materials. Below are the key issues of granite, with a very brief description and a link to a page that discusses the issue in detail. Granite is a natural product, strip mining is used to extract it, resulting in massive pollution and permanent land loss. Hardly the green product some sites claim it to be. It is a porous material as well as permeable, and has massive capillary action, leading to cleaning damage, efflorescence, staining, water marks, soap stains, surface haze, bacteria and mold colonies resulting in odor and health risks, and sink rail splitting from rod corrosion. Porosity also leads to water damage in granite, hydrolysis, hydration, even bacteria that actually eat the stone. Sealers are necessary to keep the top looking decent, with some very harsh and dangerous chemicals or solvents as well as stripping solvents used in maintenance . Recently, some companies are offering lifetime warranties against staining, yet upon reading the fine print one can see that at best the warranty is worthless. The crystalline structure is a product of the minerals it is composed of, quartz, fieldspar, silica, and mica being the main ingredients, along with a wide variety of minerals in various combination. Unfortunately, while quartz is very hard, it shrinks as it cools, resulting in fissures and porosity. The very hardness of the quartz leads to "plucking", where the saw blades and tooling plucks quartz crystals out intact instead of cutting them, resulting in a "pit" that requires resining, which leads to yellowing, fading, and more chemicals. Donnyification (the use of wood stain on granite) is used attempt to match edges to the resined top, which lasts about as long as you would think it would. The quartz is also responsible for radon gas, which is a byproduct of radioactive decay of radium found in all granites. The more quartz, the more radon and radioactivity in the granite. As the radon breaks down, the loss of electrons and particles deteriorates the atoms that form the crystalline lattice of the quartz, causing the top to slowly deteriorate and the lead levels of the granite to increase. The feldspar in the granite is eventually turned into clay if any moisture is present. The silica present leads to silicosis in workers, especially those who smoke. The fissures lead to cracking, breakage, flaking, and even more fissures as the material ages. The conglomeration of material that makes granite so interesting leads to many issues, water damage, etching caused by trace minerals, unknown composition from slab to slab, oxidation, rusting, yellowing, flaking, abrasions, hard and soft areas that make edge work challenging, and stone that can be crumbled with bare hands. Many stones are sold with mesh backing that holds it together for polishing and shipping, a sure sign that while it might be pretty, it is pretty weak as well. Some minerals that are present in some granites are soft enough that table salt can scratch the granite. Veining and movement are caused by the mixing of magma with streams of minerals causing veins which while unique also form weak points in the slab. Matching the material at seams can be difficult for stones with a lot of veins, grain and movement of colors. Samples from a slab will look a dozen different ways due to the lack of consistency, making it hard to match other materials to the countertop. Grain can also cause a lot of waste during cut out. The very heat and pressure that form the granite causes stress in the material after it is extracted, cut into slabs, and polished. The Marble Institute of America, the MIA, has seam standards that reflect this, allowing for 1/32 of an inch "lippage" at the center of a seam. Some granite is so stressed that it has been known to stop a 40 horsepower diamond saw while cutting, or after cutting partially through, it snaps like a gun shot, breaking along fissure lines instead of cutting straight. Slabs can bow as well, even sag into a curve if not stored with continuous support. Sub ducted sedimentary based granites can be flaky and weak, with a lot of variation in mineral composition. Polished granite is one of three finishes available, flamed and honed being the other two. While polishing creates a high gloss, it also makes it possible to damage with cleaning products or scrub pads, etch with common household food items, and on some granites finger prints, crumbs, even cleaning streaks can be troublesome. The flamed finish is pretty bumpy, normally used for floors. But like the honed surface, it is near impossible to repair when scratched. Variety of granite is increasing due to the demand for granite, yet many materials currently sold would have been rejected years ago as being too weak, soft, or brittle for countertop use. The sheer variety of material leads to problems knowing how a stone will hold up, as well as the trade practice of renaming stones for marketing purposes, leading to multiple names for the same stone. The differences in performance of all these varieties of "granite" can lead to wild claims by the salesmen, scratch resistant, stain resistant and invisible seams are the most abused claims. Due to the wide variety of stones and their varying performance, a blacklist was put together by one stone association but this list was removed from public access once consumers found out about it. The hardness of granite means that it is also very brittle resulting in breakage, sink rail failure, poor quality edge work bad due to hard and soft spots in the granite, increased cost of fabrication costs due to the diamond tooling needed and extra time needed. Many stone sellers will claim that the cabinets are to blame when a granite top breaks instead of the extreme brittleness of the material. The high density of the material make a substantial top but lead to worker injuries, even deaths from slabs falling on workers, so much so that OSHA is currently inspecting granite shops as a priority. There has been at least one death of a consumer, or rather a consumer's six year old child, from A frames collapsing and falling domino style. The density also makes granite a heat sink, so any hot pots set on a granite top will transfer heat quickly, resulting in burns from homeowners touching the granite where the pot had set just a short time before. High heat will also damage the stone itself, causing quartz crystals to expand and pop out, even cracking the stone itself from excessive and rapid heat expansion. World wide availability has given the consumer a wide range of choices, yet many of these countries do not have the infrastructure to deal with the environmental damage, nor the social costs from worker deaths and injury, exploitation of workers, and even the use of child labor to process quarry scrap into export products. India, Africa, Brazil, and China are the worst offenders, but socially responsible granite is a rare find. Some countries are considering a granite export ban until these issues have been addressed. Strangely enough, there is even a terrorist connection with the granite industry. Osama Bin Laden's family have extensive holdings in the granite industry, a fact that many in the granite industry would prefer to remain unknown. Perhaps it takes someone with connections to keep quarries operational in some of the war torn countries. I know that your average American consumer would prefer to know if their hard earned money might become available to terror groups or those funding road side bombs in Iraq. Many countries, alarmed by the surge in granite use in homes, have sponsored studies into the health aspects of granite, mostly radiation issues and Radon gas exhalation rates. China was so concerned with the radiation levels of granite that they started classifying and regulating it into four levels, with only the safest level being suitable for use in Chinese dwellings. Silicosis is a well studied problem from the last century, once almost eradicated as an industrial disease, yet making a comeback due to the boom in granite countertop fabrication. The lower prices of exported granite from China is mostly due to the banning of the three lower levels from being used inside Chinese dwellings, yet the regulations do not prohibit export. In the mid '90's, when the ban became effective, the Indian granite industry was reeling from the price drops, as well as the Brazilian granite industry which was saved by a 40% drop in their currency that allowed them to continue exporting stone. The demand for cheap stone slabs has opened up quarries with poor quality equipment and inexperienced labor, leading to calibration issues, kerosene lubrication to cut costs of production, poor quality polished surfaces, and chemically doctoring of stones to resemble high demand stones. The sudden drop in material costs made granite affordable, leading to today's bargains. Who would have ever thought that granite could be bought for less than a laminate countertop? However, there was a lag of a few years between rock bottom material pricing and the retail pricing levels leading to an abnormal profit margin on granite fabrication. As in any other market, high profit margins soon lead to more competition. Employees started quiting their jobs and opening up their own shops due to the low entry level requirement of tools and equipment. While some of these workers were experienced, most were not, and few had the experience or business skills to run a reputable shop. The lack of financial backing, supervisory experience, and accounting systems that kept quality levels reasonable in the experienced shops were absent in these new shops, leading to a lot of customer complaints. Bad reputation for stone and shops came quickly, causing these shops to drop pricing in an attempt to survive. Reputable shops soon found they had to match these prices, leading to a downward spiral in pricing, a boon to consumers, or at least to the lucky ones that happened to find a decent shop. Currently the prices seem to have bottomed out with some of the newer shops going out of business, which will lead to higher prices as the market stabilizes. Whether the granite industry can recover from the loss of reputation and consumer complaints is yet to be seen. The west coast is having a surge of large homebuilders refusing to install granite due to warranty issues, relying on Quartz or Solid Surface instead. Recently, on a consumer complaint site called Rip Off Reports, I ran across this quote from an outraged consumer, no doubt plagiarized from somewhere : "The granite business has been described as a long dark hallway through the countertop industry where thieves run free, and good men die like dogs for no good reason. There's also a negative side." Without a reputable trade organization that regulates the trade practices, it will remain an industry rift with false advertising, lack of certification or industry response to problems, leading more and more consumers likely to have a bad experience. There is one stone association attempting to raise quality levels, but they are finding it difficult to get consensus on standards due to the variety of shops represented, from China blank driveway fabricators to full service fabrication shops. One man's definition of quality is another man's shoddy work. To complicate matters, there are the old school shops and the newer shops with totally different ideas of how stone tops should be made. Many of the older shops simply do not like change. The old MIA standards are good enough in their view, while the newer shops tend to think that things can be done better. Few of the old shops will seal granite counter tops, thinking it a waste of money. In their defense, most of the stone these shops learned to work with years ago did not need sealing, if it was that porous, it just wasn't used. To them, saying that stone needs water tested frequently and sealed is an admission of weakness of the material. Many of the old shops will not rod sink and cooktop rails, after all with no warranty on the tops, it is just added expense on their part. Another example of poor quality standards is the MIA seam standards. . Granite typically has visible seams, which the MIA industry standards say can be up to 1/16th of an inch wide, with another 1/16 of an inch bevel on each side, making an average seam up to 3/16 of an inch across, with up to 3/32 of an inch "lippage" (one side higher or lower).That is over a 1/16th of an inch. When you add in tolerance levels, seams can be 1/4" wide and still meet industry standards. Seams are unsanitary, trapping bacteria and mold, and seams can pop apart easily if the home or cabinets settle. One stone fabricator brought up a good point, that the Solid Surface industry was fortunate that the manufacturers' warranties made standards essential. New brands had to offer long warranties as well to compete, many even upping the ante to 15 years over the standard 10 year warranty. To get a certification, solid surface shops have to have at least one certified person for each brand they sell. Most manufacturers' require tooling and shop requirements, preferring those shops with an investment to protect over someone working out of a pickup truck. But the stone industry has few entry barriers, merely the ability to pick up the slab or the ability to unload a slab from the slab yard's truck. Some stone fabricators have it loaded on their trailer, then cut it up while on the A frame to save the expense of a fork lift as well as shop overhead by using customers driveways. With little tooling, experience, nor decent working conditions, it is no wonder poor quality tops get made. Many shops are rented industrial park buildings, making it easy to pick up stakes and change names when a reputation for poor quality work catches up with them or their "lifetime" warranties start costing them money. Illegal workers find granite work a good niche, low cost entry levels, a large amount of unskilled labor needed, no certification or regulation required. There is little to force these companies to provide worker's compensation protection for the workers, nor general liability insurance leaving homeowners wide open to injury lawsuits and property damage. Granite is available in large slabs that can minimize seams, averaging 50 to 60 square feet. It also leads to a lot of waste, averaging 35% industry wide. A good solid surface job, using smaller sheets and even half sheets, will have little waste. A full sheet of solid surface is around 30 square feet, a half sheet 15 square feet. Scrap from one sheet can be used for edge buildup, seam blocks, backsplash, window sills, even seamed and glued into larger pieces for countertops. The average stone shop has tons of scrap littering their yards, even more is sent to the landfill. By far the worst problem caused by the large slab sizes is the injury and accidental death of workers. A full size granite slab will weigh over one thousand pounds, enough to crush a man, even amputate limbs. Slabs are handled with slab clamps which grab the center of the sheet. If the slab breaks, the suddenly unbalanced slab can easily crush feet and hands, even swinging out of control to kill workers. A-frame failures have killed many workers, falling like dominoes, dozens even hundreds of slabs collapsing in some cases. |
