Concrete scupper drain

Types of Concrete Scupper Drains

A concrete scupper drain is a drainage feature typically placed on the edges of structures. Its primary role is to channel water runoff, ensuring that surfaces remain clear and safe. Scupper drains come in various types, each designed to fulfill distinct drainage requirements. Here are some of the most common types:

• Scupper with a Slide Rail:

  This type of scupper drain has a slide rail that acts as a cover. It is usually placed on the drain’s surface to direct water into the channel below. The slide rail can be made of different materials like stainless steel or hot-dip galvanized steel.

• Scupper with a Lattice:

  A scupper with a lattice is a type of scupper drain that features a lattice-like top. This design allows water to flow through while preventing large debris from entering the drain. Scuppers with lattice tops are commonly used in landscapes and pedestrian areas.

• Scupper with a Grate:

  Scupper drains with grates are designed with a removable metal grate on top. This allows for easy access for maintenance and prevents large objects from entering the drain while permitting water to flow freely.

• Concrete Scupper Drain with Downspout:

  A concrete scupper drain with downspouts is a drainage system integrated into concrete surfaces like parking lots or sidewalks. These drains are designed with vertical pipes extending from the scupper, directing rainwater or runoff water into an underground drainage system, thus preventing surface flooding and water accumulation.

• Gutter Scupper:

  A gutter scupper is a drainage feature integrated into a building’s gutter system. It serves as an outlet for excess water during heavy rainfall or overflow conditions. By allowing controlled water release, gutter scuppers prevent gutter overflow, reducing the risk of damage to the gutter infrastructure and surrounding areas.

• Cove Scupper:

  A cove scupper is a drainage solution designed for areas where water pooling is a concern. Its cove-like shape, resembling a small indentation or recessed area, directs water towards the drain outlet. This proactive design prevents water accumulation in critical zones, enhancing the overall effectiveness of the drainage system.

• Parapet Wall Scupper:

  A parapet wall scupper is situated on buildings with parapets. These scuppers are strategically placed to manage water drainage on the parapet wall, especially during heavy rain. By directing water runoff away from the building's edges, parapet wall scuppers prevent water infiltration, protecting the structure's integrity and aesthetics.
