Insertion module for leading-through e.g. concrete wall, for feeding line i.e. cable, through building part, has sealing surface provided on outer side of duct body and including sealing material that forms creep waterproof boundary surface

摘要

The module has a duct body (RO) surrounding an internal space with a longitudinal axis (LA). A sealing surface (DF1, DF2) is provided on an outer side of the duct body, where the sealing surface is circumferentially closed around the duct body. The sealing surface includes a sealing material that forms a creep waterproof boundary surface with a hardening ready-mixed concrete. The sealing surface is formed on a carrier body (DT) that is connected with the duct body in a circumferentially sealing manner. Two membranes are arranged spatially in an axial direction. An independent claim is also included for a method for producing a concrete wall under utilization of an insertion module.
