As soon as it rains, there is a stagnation of water fringe on practically all the tiles on the tiled terrace on plots (tiles 60 x 60 cm and 2 cm thick) resting on a concrete slab created by a landscaper. The latter found this normal and explains that it is due to a physical phenomenon (air circulating under the studs which goes up by the sides of the tile and which blocks the flow of the water). We have not been warned. How to adjust this retention in border of tiles?

The phenomenon described by the landscape is known. It is more or less amplified by the speed and direction of the wind. It all depends on what is considered "acceptable", or not. Normally, this phenomenon of water retention must disappear rather quickly after a shower. If this is not the case, ask the landscaper to quickly fix the problem.
