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

Well, whether there is just a thin layer of moisture on it due to a roof cover or several centimeters of standing water, it probably doesn’t make a difference for small cracks where water could penetrate.
As a construction layperson who understands some physics, I would say that the mortar and joint compound need to be applied in a way that no cracks form. Anyway. Maybe thinner? At least not "damp from the ground"!

You still have connection joints Where else except right at the front door? That one is covered

And yes, I meant exactly that joint.
