All floors that are accessible barefoot and those of pool floors less than 1.50 metres deep are non-slip but not abrasive.
To avoid water stagnation, the slopes of the decking should be between 3% and 5%; floor drains should be sufficient in number and positioned accordingly.
Protruding elements such as benches, planters and ducts located at a height of less than 2.50 metres must be designed and protected so that they have no sharp edges.
