Shaped like a “U” or channel to catch water (e.g., where the edge of a tile roof meets a wall). Through wall flashing Spans the thickness of the wall and directs water to weep holes. Cap flashing (drip cap) Often used above windows and doors. Drip edge A metal used at the edges of a roof. Step flashing (soaker, base flashing)
In architecture, a hood mould, hood, label mould (from Latin labia, lip), drip mould or dripstone [1] is an external moulded projection from a wall over an opening to throw off rainwater, historically often in form of a pediment. This moulding can be terminated at the side by ornamentation called a label stop.
Water falls towards a parapet gutter, a valley gutter or an eaves gutter. [12] When two pitched roofs meet at an angle, they also form a pitched valley gutter: the join is sealed with valley flashing. Parapet gutters and valley gutters discharge into internal rainwater pipes or directly into external down pipes at the end of the run. [12]
Rainscreen cladding principle Air circulating scheme. A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture-resistant surface of an air/water barrier applied to the sheathing to create a capillary break and to allow drainage and evaporation.
Steep roof materials are roofs that are only recommended where water can freely and openly drain off the edge of the roof without retaining water for too long. [1] The aim is to drain off water completely due to the high water permeability of most of these materials, for instance: the Thatched roofs.
A diagram of a traditional French drain. A French drain [1] (also known by other names including trench drain, blind drain, [1] rubble drain, [1] and rock drain [1]) is a trench filled with gravel or rock, or both, with or without a perforated pipe that redirects surface water and groundwater away from an area.
A street gutter is a depression that runs parallel to a road and is designed to collect rainwater that flows along the street diverting it into a storm drain. A gutter alleviates water buildup on a street, allows pedestrians to pass without walking through puddles, and reduces the risk of hydroplaning by road vehicles.
Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface.
