Abstract
A through-penetration device has a molded body consisting essentially of an intumescent foam material and having at least one penetration opening for one line. An outer contour of the molded body has protrusions extending radially outward for anchoring within a cast building component, which protrusions form undercuts in building component as the building component is being cast. In addition, a mounting plate that can be axially pushed onto the through-penetration device, sealing the penetration openings, is provided. As the through-penetration device is produced, a liquid coating material is applied to a surface of a foaming mold, and then a foam mass containing a predetermined percentage of intumescent material is introduced into the foaming mold. After a foaming process, the coating material forms a water-impermeable skin on the foamed molded body.
