Capillary-grooves, drip grooves, capilary breaks. Grooves in various building components to stop water traveling uphill by means of surface tension and or capillary action. Capillary action and surface tension allow water to flow up hill.

In this post, we’re going to talk about the 7 design techniques for keeping water away from the building: shed, overhang, drip, overlap, drain + weep, capillary break, and labyrinth. Then, stick around to the end, and you’ll learn a helpful exercise we perform on all our design projects to ensure a watertight design.

Key principles include provision of falls, drainage, overflows, anti-condensation, anti-capillary, correct product selection for application, care of the installed product, allowing for normal building movement and the like. 1.4 As a “roof” to either……

Apr 15, 2022 · The traditional way of dealing with surface tension is to “break” the surface tension with a “kerf” and create a “drip” or to provide…yes you guessed it…a “drip edge”. Figure 1: Surface Tension - Rainwater can flow around a surface as a result of surface tension.

Sep 9, 2020 · Drip edges are placed along with the eavestroughs of roofs. The eaves are the edges of the roof that hang over the face of the wall connected to the roof. Beneath these eaves are long, narrow open containers that water and other liquids can run through.

Jan 13, 2025 · What Is A Drip Edge On The Roof? A drip edge is a metal flashing that is installed on the edges of the roof to protect it from runoff water. This further shields the water away from fascia and gutters and protects the underlying roofing structure from moisture accumulation.

Jan 7, 2024 · Result: failure. Water running down the freshly rendered walls, staining them.Also the water that did drip off just hit the door sills of the doors beneath, making an irritating drumming sound.

Dec 23, 2024 · Installing a drip edge on an existing metal roof is a practical and effective way to enhance its performance and longevity. By adding metal flashing along the roof’s edges, a drip edge efficiently directs water away from the structure, preventing moisture-related issues and protecting the roof’s integrity.
