END DAMS & PRE-FORMED FLASHING CORNERS
A structure is vulnerable to harsh environmental conditions if it is not protected in the early stages of construction. The theory of an ounce of prevention being worth a pound of cure, holds true in the construction industry today. Installing a proper drainage system in cavity wall construction, is critical for a buildings continued existence. The cavity wall must possess effective flashing, end dams, corners and a good weeping system to allow moisture to dissipate correctly. By initially installing a proper drainage system, potential structural problems are prevented in the future. For years, Sandell® has provided a complete line of thru-wall flashings and masonry accessories that promote proper drainage in a structure. Today, Sandell® is offering pre-formed end dams and corners to further enhance and complement our current drainage system.

Sandell®'s Pre-Formed Flashing Corners
Sandell®'s Pre-Formed Flashing Corners are used to secure structural integrity by creating a moisture barrier that upholds a watertight environment. By effectively redirecting the moisture and blocking the various elements, Sandell®'s Pre-Formed Corners form a shield of defense against all of the common offenders that have the tendency to weaken and eventually break down a structures composition. Conventional methods used to flash corners required cutting, patching, folding and overlapping of the material to make it fit properly. This technique basically redesigned the flashing so it would accommodate the corner to the best of its ability and basically get the job done. However, by lapping, seaming, cutting and initiating any changes to the flashing, the material lost its element defying characteristics. Pooling and seepage occurred that further complicated the application.

Today, Sandell®'s Pre-Formed Flashing Corners are seamless, durable and best of all simple to use. They are pre-formed, which means no cutting, bending or forming on the jobsite. This priceless feature, along with the products many other amenities, adds to the value that this product has to offer to the consumer. The ease of use and expedient installation process delivers a cost effective system with substantial savings.

Sandell®'s Pre-Formed Corners are available in Stainless Steel - 26g, 28g; Copper -10oz, 12oz, 16oz, and 20oz, or Self Adhering Rubberized Asphalt.
