In construction, a “scupper” refers to an opening in a wall or parapet that allows water to drain from a roof or deck. Scuppers are essential components of a building ‘s drainage system, preventing water accumulation and potential damage. Proper installation of scuppers is essential for ensuring effective water management and protecting the structural integrity of the building.

Function

The primary function of a scupper in construction is to allow water to drain from a roof or deck, preventing water accumulation and potential damage. Key aspects of the function of a scupper include:

  • Water Drainage: Scuppers allow water to flow from the roof or deck to the exterior of the building, preventing water accumulation and potential damage.
  • Preventing Damage: Scuppers prevent water from pooling on the roof or deck, reducing the risk of leaks, structural damage, and mold or mildew growth.
  • Protecting the Building: Scuppers protect the structural integrity of the building by directing water away from the roof, walls, and foundation, preventing water damage and deterioration.

Types of Scuppers

There are several types of scuppers commonly used in construction:

  • Box Scupper: A box scupper is a rectangular-shaped opening in a wall or parapet, typically lined with metal, that allows water to drain from a roof or deck.
  • Circular Scupper: A circular scupper is a round opening in a wall or parapet, typically lined with metal, that allows water to drain from a roof or deck.
  • Corrugated Scupper: A corrugated scupper has a corrugated design, providing additional strength and efficiency in draining water from a roof or deck.

Applications

Scuppers are used in a wide range of construction applications, including:

  • Residential Buildings: Scuppers are used in residential buildings to drain water from the roof, preventing water accumulation and potential damage.
  • Commercial Buildings: Scuppers are used in commercial buildings to drain water from the roof, preventing water accumulation and potential damage.
  • Industrial Buildings: Scuppers are used in industrial buildings to drain water from the roof, preventing water accumulation and potential damage.

Installation

Proper installation of scuppers is essential for ensuring effective water management and protecting the structural integrity of the building. Key aspects of the installation process include:

  1. Design and Placement: Design the scuppers and determine their placement on the roof or deck, ensuring adequate drainage and compliance with building codes and regulations.
  2. Prepare the Opening: Prepare the opening in the wall or parapet for the scupper, ensuring it is properly sized, positioned, and flashed to prevent water infiltration.
  3. Install the Scupper: Install the scupper into the opening, ensuring a proper fit, alignment, and attachment to the roof or deck.
  4. Seal and Flash: Seal and flash around the scupper, ensuring a watertight connection between the scupper, roof, and wall, and preventing water infiltration.

Conclusion

In construction, a scupper refers to an opening in a wall or parapet that allows water to drain from a roof or deck. By preventing water accumulation and potential damage, proper installation of scuppers is essential for ensuring effective water management and protecting the structural integrity of the building in residential, commercial, and industrial construction projects.
