Where should weeps be located in a wall section detail?

Weeps are essential components in wall construction, primarily for moisture management. They allow any trapped water within the wall assembly to drain out, preventing damage to building materials and reducing the risk of mold growth.

The most effective location for weeps is above the flashing, specifically the 6 MIL polyethylene flashing. This placement allows water that condenses within the wall assembly to be directed to the exterior, bypassing the interior materials and minimizing potential water damage.

When weeps are situated above flashing, they also help facilitate drainage from any moisture that may accumulate due to rain or debris clogging the wall system. This ensures that any water that might penetrate the exterior layer is effectively channeled out before it can reach vulnerable components, such as insulation or structural framing.

While placing weeps at the base of the wall could seem logical, it does not account for water that may collect higher in the wall system. Similarly, locating them at the top of the wall or in the center does not provide a direct pathway for water to exit. Hence, positioning the weeps above the flashing is optimal for ensuring effective water management and prolonging the integrity of the wall assembly.
