engineered stone manufacturing process - Utand Stone Machinery
  • Engineered stone is a composite material made of crushed stone bound together by an adhesive, (most commonly polymer resin, with some newer versions using cement mix). 
  • This category includes engineered quartz, polymer concrete and engineered marble stone.
  • It is like terrazzo except its made in factory and cut into various blocks.
  • Engineered stone is non porous, more flexible, and harder than many types of natural stone.
  • Its composition is 66% quartz and 34% resin by volume.
