Outdoor flooring cannot ignore compliance with codified and regulated standards: they must be waterproof, anti-slip, anti-freeze, resistant to loads, atmospheric agents and thermal changes. The thicknesses and correct installation are also important. It is then necessary to consider the intended use (garden, driveway, pedestrian path, pavement of a poolside ...), identifying the material that best suits the context and climatic conditions of the place.
Some types of marble are among the most suitable stone materials for outdoor use: the historical tradition in marble processing and the proposal of natural materials for building and contemporary architecture, have led Margraf to achieve high levels of excellence and quality in the combination and in the selection of finishes, sizes and shapes for the outdoor spaces of private homes, residential complexes, hotels and public places.
Unique, non-slip, anti-freeze materials for outdoor flooring (all Margraf marbles have been found to be anti-freeze and resistant to the coldest temperatures, according to the UNI EN 1341: 2003 standard), processed to meet the needs of designers and architects. There is a wide range of products offered by the Vicenza company, in modular formats (30x30, 40x40, 30x60 cm) or in the 30/40 cm version, all starting from 3 cm thick.
There is also a wide choice of finishes: Margraf technological research has developed a series of surface finishes for a particular aesthetic result and a high degree of anti-slip and safety. Among these, bush hammering: a process that gives the marble a rustic appearance, eliminating differences and variations. The bush-hammered effect is obtained with a pyramid-tipped hammer, and the final result can be coarse or fine, passing through various intermediate degrees of finish; rifling: characterized by a succession of side-by-side grooves, performed by means of diamond discs or a wide range of variable profile tools; flaming: a process that can be obtained using oxygen and gas.
The flame acts by hitting the surfaces to be treated at a high temperature (2500/3000 ° C), which undergo a thermal shock, causing a phenomenon of expansion and therefore thermal splitting. The surface texture will appear rough and raised. Flaming is particularly suitable for exteriors, but must be used wisely only on marbles that resist severe thermal changes.
