What is the maximum allowable slope for a pool deck?

The maximum allowable slope for a pool deck is established to ensure safety and accessibility for users. A slope of 1:50 means that for every 50 units of horizontal distance, there is a rise of one unit. This ratio provides a gentle incline, which helps with proper drainage while minimizing the risk of slipping or falling. A slope that is too steep can create hazards, particularly when the deck is wet, making it important to adhere to guidelines that balance functionality with safety.

The other ratios indicate steeper slopes, which could compromise the pool deck's effectiveness in draining water and increase the potential for accidents. Thus, the 1:50 slope is not only practical for drainage purposes but is also compliant with safety regulations, making it the correct choice.
