In which direction should waterproofed decks slope?

• A. Toward walls
• B. Away from walls
• C. Horizontally across the deck
• D. In a circular pattern

Answer: (B)

Waterproofed decks should slope away from walls to ensure effective drainage and prevent water pooling. When water accumulates against walls, it can lead to several issues, including moisture infiltration, mold growth, and structural damage. Sloping the deck away creates a natural pathway for water to flow towards drains or designated drainage areas, allowing for efficient runoff and minimizing the risk of water-related damage. The other options would not address these drainage concerns effectively. If the deck slopes toward the walls, it can cause water to collect against the wall, increasing the chances of leaks and other water intrusion problems. A horizontal slope does not facilitate drainage, leaving standing water on the surface, which can also lead to damage over time. A circular pattern would complicate drainage efficiency and could lead to inconsistent water flow, enhancing the risk of pooling in certain areas. Therefore, sloping the deck away from walls is the best practice to ensure proper drainage and maintain the integrity of the structure.
