Concrete section seam has top-hat profile for seal injection hose

摘要

A hose injects a sealing mass into the seam between two sections of concrete forming part of a building structure. The hose is pre-installed and fitted within an elongated protective top-hat profile (1) with lower open face (4) forming a channel (9) for the injection hose. Both lower faces of the profile have an elongated elastic seal. Parts of the profile incorporate an opening (5) through which sealing mass may be expelled.
