The Mapestone Line and the new UNI 11714-1:2018 Standard

DURABILITY AND SAFETY

These are the essential requirements of natural stone paving according to the UNI 11714-1:2018 standard, together with regularity, maintainability/cleanability, sustainability and specific performances.

Durability and safety must be already planned during the design phase and are influenced by:

■ environmental and working conditions;

■ nature of the substrate;

■ design quality;

■ product quality;

■ installation quality.
