A continuous trough, fabricated on-site, designed to channel rainwater away from a building’s foundation and exterior walls. Constructed from a single piece of material, typically aluminum, copper, or steel, this system eliminates the vertical joints common in traditional sectional designs. These joints are often points of weakness, prone to leaks and debris accumulation.
The principal advantage of this type of rainwater management system is its increased durability and reduced maintenance requirements. The absence of seams minimizes the risk of water damage to the structure and landscaping. Historically, the creation of these systems became practical with the advent of portable roll-forming machines, allowing for customized lengths tailored precisely to the building’s dimensions. This has significantly improved water runoff efficiency and aesthetic appeal compared to older segmented systems.
