What is Terastone

From natural aggregate to slab

Terastone is a surface material in slab form, made by combining crushed, screened and washed marble, basalt, granite and quartz aggregates of 0.1 mm to 10 mm grain size with BRETON vacuum-vibration technology.

Apart from natural aggregate and cement, no chemical materials such as polyester or resin are ever used as a binder.

It is cut to size from 68×150×3 cm slabs and used indoors and outdoors. As an alternative to materials such as marble, granite, limestone, ceramic, quartz and terrazzo, it can be used with confidence in every kind of building.

Technology

Vibration under vacuum

The very low water/cement ratio and the vibration-under-vacuum system produce a non-porous, compact material.

Aggregate

Crushed, screened and washed marble, basalt, granite and quartz aggregates; grain size 0.1–10 mm.
Vacuum-vibration

Aggregate and cement are compacted in the BRETON vacuum-vibration system at a very low water/cement ratio.
Slab

A compact 68×150×3 cm slab is produced; it is then cut to size and its surface finished.

Flexural strength

Extremely high strength (11.50 N/mm²).
Water absorption

Volumetric water absorption is extremely low; water absorption by weight is 1.5–2.5%.
Gloss

Thanks to its non-porous surface the gloss is very high (65 gloss).
Homogeneity

Thousands of square metres can be made without any change in colour, texture or appearance.
Fire and health

It belongs to the non-combustible, non-radioactive category; it does not ignite or release toxic gas.
