Load-bearing capacity – Tests performed in an accredited testing laboratory have shown that the load-bearing capacity of tiles depends on the load-bearing capacity of the bedding. When installing on concrete bed, if tiles are laid properly, tiles break only while the bedding breaks.

Terrazzo tiles meet the following standards:

PN 72 3210 “Single-layer terrazzo tiles” ČSN EN 1339:2003 “Concrete tiles – Requirements and testing methods” TN 09-17-01a “for conformity assessment of product: Concrete, granitoid and terrazzo tiles” ČSN 744507 “Determination of anti-slip properties of floor surfaces” PN-91/B-10130 and regulation of SÚJB no. 307/2002 Coll. “On radiation protection” as amended by regulation no. 499/2005 Coll. The tiles are not hazardous to human health.
