I would like to start my very first post here in the forum quite boldly with a question.
We want to pave our terrace with natural stone, and porphyry and sandstone slabs seem to be particularly popular.
As a layperson, I would appreciate your advice. What should I really pay attention to, and which natural stone would you recommend based on your experience?
Respectfully,

Hello,
Just as important as frost resistance for patio slabs is the surface texture of the stone (slip resistance). Stones with polished surfaces should be avoided, as they become slippery when wet.
Properties of porphyry include high compressive strength, abrasion resistance, and acid resistance, as well as a long lifespan. However, not all porphyry is frost resistant, depending on the quarry location.
Sandstone is generally frost resistant but not resistant to de-icing salt. It is durable, long-lasting, and has good thermal conductivity. However, sandstone is usually quite prone to staining.

You shouldn’t only consider slip resistance but also the cleanliness of natural stone surfaces. It’s easy for a drink to spill or a greasy sausage to slip off the plate, which becomes a problem if stubborn stains cannot be removed.
I chose concrete patio slabs back then. Because of their color, the concrete slabs have a Mediterranean style and look similar to natural stone. Additionally, concrete slabs are significantly more affordable than natural stone.
Hopefully, this is helpful.
Best regards,
Dennis
