Is stone carpet waterproof?
No. Stone carpet is porous by design, so water drains through it. Wherever there is a room below, such as a porch roof or a balcony, Rayson SealForce RC40 goes underneath and is tested before the stone carpet.
The resin binds the pebbles to each other, not the cracks of the slab underneath, so the membrane does the waterproofing and the stone carpet gives the finish and the grip. On paths laid on the ground, the falls and the drains are checked so water leaves the surface.
