The invention relates to an arrangement and a method for sealing Joints in buildings, in particular of expansion joints in an external facade.

Such joints can, for example, in a masonry or in a Concrete wall of a building, for example, at a transition from old and new walls, in an extension, or between long ones monolithic Baulöcken arise or be provided. Also in the Exterior facade of buildings, usually at least one on one Masonry or a concrete wall applied thermal barrier coating as well additional layers applied thereto, for example a plaster layer, includes, joints are often provided, in particular expansion joints. Such Expansion joints are said to expand or contract the building materials compensate due to temperature fluctuations. For sealing the Joints to the outside, in particular to a penetration of moisture in the To prevent building wall are different sealing arrangements known.

In DE 197 19 501 A1, for example, an arrangement for sealing of Expansion joints in a plaster layer and a thermal barrier layer comprehensive Facade of a building described on both sides of the expansion joint arranged two-legged joint profiles made of plastic, which with frontally opposite joint legs in the expansion joint the Limit thermal barrier coatings.
