Basic concept of gutters and downspouts

Channels and downspouts are fundamental elements in the drainage and evacuation systems of rainwater and wastewater in construction. The channels are responsible for capturing and conveying surface water, generally from roofs or paved areas, to downspouts. Downpipes, for their part, are vertical conduits that transport water from the channels to the evacuation or storage systems, avoiding accumulations and structural damage.

These components are an integral part of the hydraulic design of buildings, guaranteeing efficient and safe water management to protect the structure and its environment. Proper selection, installation and maintenance of gutters and downspouts is crucial to preventing leaks, erosion and other water-related problems.

Surface channels

Surface channels are structures designed to capture and conduct water in outdoor areas, such as sidewalks, patios, and industrial areas. They are normally manufactured with open profiles and are installed in the ground to facilitate the flow of water towards downspouts or drainage systems. Its design can be trapezoidal, rectangular or semicircular, depending on the required hydraulic capacity.

These channels are typically lined with abrasion- and corrosion-resistant materials, such as concrete, galvanized steel, or PVC, to withstand harsh environmental conditions. Its maintenance includes periodic cleaning to avoid obstructions by leaves, sediment or garbage.

Roof channels

Roof gutters, also known as gutters, are installed on the cornices or edges of decks to intercept rainwater. Its main function is to direct water towards the downspouts, preventing it from falling directly on the walls or foundation of the building, which could cause structural damage or leaks.
