The innovation relates to a seal for expansion joints in buildings in the form of a tape from an im ■ essential stretchable, weatherproof material, preferably Plastic material, with a central area covering the joint and two side areas for each Insertion in one of the parts to be sealed of a building certain edge areas. Which for Are designed to accommodate reinforcement inserts *.

A known seal for expansion joints in buildings consists of a thin, essentially flat strip of expandable material. The strip has a central area covering the joint and two lateral areas for adhesive inclusion in concrete or wall- ■ ω-οχ-ϊτ j wi.g crQihi τ date Bex "eiciie s.uiT- with hollow longitudinal ribs in the lateral areas for inclusion of reinforcing bars are provided.
This known seal is difficult and consequently

The mooring solves this problem with a seal dor initially mentioned type in that inside Reinforcement inserts that are extended over the entire area of the edge areas are firmly enclosed, e.g. built-in. poured, are.

Various elastic materials can be used as sealing material; are particularly suitable, for example wise natural or artificial rubber and elastomeric synthetic materials »butyl rubber and an under Materials known as "neoprene" are particularly suitable.

The reinforcement can be made of drawn or

The reinforcement layers can be in the sealing strip during the manufacture of the same, e.g. during the calendering process, are inserted, namely such that the reinforcement layers completely in the weather strip are included. The finished strip waist in a shape in which it is easy to 'Can be rolled up for storage and transport purposes.

For a better connection of the concrete edges or another building material of the structural parts to be connected holes can be punched at intervals through the reinforced edge areas in a manner known per se, so that concrete bridges are created through these holes, which hold the seal and the structural parts stabilize yourself.
