TT-HWA is a quick and affordable solution to protect the facade against water damage during new construction or renovation.

The weather on construction sites is getting colder and wetter again. Downpipes, also called rainwater drains, are always installed last in construction, after the pointing of the brickwork. Long before the brickwork is finished, the roof including gutter and outlets is usually already completed, but the installation of the downpipe is postponed so as not to hinder the bricklayer. In the meantime, the facade must be protected against dirt and water damage.

A quick and affordable solution to protect the facade against water nuisance during new construction or renovation is the Temporary Rainwater Drain from Tilmar (TT-HWA).

TT-HWA is available in two sizes: Ø80 mm and Ø100 mm. The hose is quick and easy to install and remove. It is a strong, thick, flexible PE hose in blue, intended for single or limited use.
