Natural stone paving

Natural stone paving is a paving with a covering of solid natural stone, which is extracted in quarries by drilling and blasting and further processed into paving stones in the natural stone factory by machine or manually by splitting. Paving stones made of natural stone are subject to natural fluctuations in terms of their shape, colour, surface finish and quality. Tolerances regarding their dimensions are regulated in DIN EN 1342.

Application:

• public footpath and street spaces.
• private areas, e.g. driveways, garage forecourts, garden paths, terraces, roof gardens and terraces.
• paved areas that serve for infiltration ("eco-paving")
• De-icing areas (depending on the type of rock)
• Mostly cube-shaped blocks as large, small or mosaic pavements, but also paving slabs, laid in associations.

Surfaces: Surfaces of natural stone paving are usually considered to be sufficiently slip-resistant, as a rough-cracking surface is retained, especially with classic paving formats, which is sufficiently grippy due to its natural unevenness, but if the surface slope is insufficient, it also promotes puddles forming on the surface, which can lead to slippery conditions when wet and black ice in winter.

Properties: The respective natural stone-specific properties apply. As a rule, the typical types of rock used for paving are highly resistant to frost and de-icing salt and also have high abrasion and pressure resistance.

Types: Typical natural stones used for paving are granite, quartzite, gneiss, basalt, basalt lava, porphyry, greywacke and diabase. Depending on where it was installed, regional types of stone are often used, such as sandstone or limestone.

Regulations: Natural stone paving is regulated in DIN EN 1342, kerbstones made of natural stone in DIN EN 1343.
