The combination of crushed natural stone and a resin binder. The binder holds the stone aggregate together. Through this combination the stone has been “engineered” to enhance it's properties, and form it into a product more workable and usable. Engineered stone countertops are made in relatively thin slabs. The marriage between stone and resin is completed under intense heat and pressure. Pigments are added during the process to give the product its color. The resulting slab is then polished to a high gloss or honed to a more matte finish.
Strong, durable, and attractive, engineered stone is very consistent in look and pattern. It is also heat-resistant and does not accumulate bacteria or mold. The surfaces are easy to maintain, too. They can be specified with bacteria-resistant surfaces, but since they are non-absorptive and resistant to heat anyway, they should not be collecting bacteria in the first place.
