Hello everyone,
We want to install a natural stone-covered entrance platform for our single-family house. It is basically just one step, approximately 2.40 x 1.20 m (7 ft 10 in x 3 ft 11 in) in size. For the material, I chose 60 x 60 cm (24 x 24 inches) flamed basalt slabs.
The platform was poured from screed several months ago. It slopes downward away from the house, so rainwater can drain off.
The question now is, do I still need a drainage system for this? The tiler says no, but a civil engineer friend says yes. If the slabs are properly glued, how could they freeze and be damaged? What benefit would a drainage system actually provide? Water would never penetrate that deep anyway.
Best regards

This joint is sealed with silicone. It just needs to be redone every few years.
It’s completely different whether you seal this one joint with silicone (which you have to do anyway for elasticity) or if you need to properly waterproof multiple panels (or get rid of the water). The entire job was done by a professional company that apparently knew what they were doing.

You can do a lot, as long as you are aware of the potential risks.
