Thanks for the question, rizzadelc85. The floors contain glass chips inlaid within the polished concrete - meant to look like terrazzo. Our team at Novell poured a specifically engineered concrete topping mix onto each floor to encase the in-floor radiant heat. We let the floors cure a little before sprinkling in the glass chips, allowing the glass to sink in a little, then the floors were ground and polished! The result is a seamless, beautifully polished clean floor with subtle imbedded colour chips, that's warm under the feet.

Wow. Thanks so much for the informative answers. :)
