Terrazzo technical information

Composition and production. Terrazzo floors and objects are made of Portland cement, marble powder, inorganic cement pigments, sand and aggregates, cement additives and recycled marble and glass pieces. These components are mixed with water and moulded. The tiles dry and harden naturally during 3 to 5 weeks. The last stage of factory production is a surface polishing, removing 2 to 5 mm to unveil the beauty of the decorative aggregates.

The tiles are intended for decorative interior use.
Applicable standards. Our terrazzo tiles are not standardised. This is due to the production method as each tile is individually handcrafted and each order is made to measure. The laboratory tests mentioned below are applicable only to the tiles tested as delivered from factory.

The laboratory tests have been carried out on Terrazzo Marble 10 MixWhite, TB tiles using various protocols and test methods for terrazzo or cement/concrete slabs. We have mostly used the Tests for Terrazzo of interior use directive UNE-EN 13748-1, for which the tested tiles have passed/are within the standards. The results of these tests are applicable only to the tiles tested.
