Abstract

The bitumen sealing strip for protection of building interiors against entry of moisture comprises an internal aluminum layer (2) which finishes at a distance (6, 6') from the strip edge, and thus allows durable homogeneous joints to be formed between adjacent strips.

Description

Als Abdichtung gegen Bodenfeuchtigkeit auf erdberührten Rohböden, als Abdichtung auf Zwischengeschossdecken über Räumen mit hoher Luftfeuchtigkeit sowie als Sperrschicht gegen nachstoßende Restfeuchte aus Betondecken werden zwischen der Betondecke und dem darauf aufgebrachten Estrich Abdichtungsbahnen eingesetzt.When Waterproofing against soil moisture on soil in contact with soil, as a seal on mezzanine ceilings over rooms with high humidity as well as a barrier against subse- quent residual moisture Concrete ceilings are placed between the concrete floor and the surface Screed waterproofing membranes used.

Unter anderem werden für dieses Anwendungsgebiet dünne Bitumenbahnen mit einer Dicke unter 1,5 mm eingesetzt, da sie besonders leicht und sauber zu verarbeiten sind. Allerdings benötigen diese dünnen Bitumenbahnen zur Erzielung einer ausreichenden Sperrwirkung eine im inneren der Bahn angeordnete, durchgehende Aluminiumschicht.Under other things will be for this application thin Bitumen sheets with a thickness of less than 1.5 mm used, as they are particularly easy and clean to work with. However, these require thin Bitumen membranes to achieve a sufficient barrier effect arranged in the interior of the web, continuous aluminum layer.

Es hat sich nun herausgestellt, dass durch die stark alkalischen Umgebungsbedingungen die durchgehende Aluminiumschicht beginnend von den Seitenrändern zu Korrosionserscheinungen neigt. Die Korrosionsschäden führen in der Folge zur Auflösung der Aluminiumschicht, damit zur Auflösung des inneren Zusammenhalts der Bahn in diesem Bereich und damit zur Undichtigkeit der Abdichtungsbahn.It has now been found that by the highly alkaline environmental conditions the continuous aluminum layer starting from the side edges too Corrosion phenomena tends. The corrosion damages result in the consequence to the dissolution of the Aluminum layer, thus for dissolution the inner cohesion of the railway in this area and thus the Leakage of the waterproofing membrane.

Die Erfindung beseitigt dieses Problem. Durch das seitliche Einziehen der Aluminiumschicht wird ausgeschlossen, dass diese mit Feuchtigkeit in Kontakt treten kann. Gleichzeitig wird durch die Überdeckung (7) der Aluminiumschicht eine ausreichende Sperrwirkung gewährleistet.The invention eliminates this problem. The lateral retraction of the aluminum layer is ruled out that this can come into contact with moisture. At the same time, the overlap ( 7 ) of the aluminum layer ensures a sufficient barrier effect.

In 1 wird der Aufbau der Abdichtungsbahn über die gesamte Breite dargestellt,In 1 the structure of the waterproofing membrane is shown across the entire width,

2 zeigt den seitlichen Überlappungsbereich zweier Bahnen im verlegten Zustand. 2 shows the lateral overlap area of two webs in the laid state.
