STUVA participating in supporting workgroup

The Federal Institute for Research on Building, Urban Affairs and Spatial Planning (BBSR) is supporting a research project into the durability of transition points between differing sealing systems to be conducted by the Aachen Institute for Civil-Engineering Failure Research and Applied Building Physics (AIBau).

Differing sealing methods are, in practice, frequently combined with one another; horizontal surfaces on flat roofs, for instance, are installed using roof-sealing strips, and the edges sealed using liquid polymers, which provide easier workability. The rules of building technology currently do not require separate verification of the durability of the transitions between these systems. It has become apparent in the past, however, that these points constitute weaknesses and frequently fail shortly after the expiry of the guarantee period, causing problems for the building owner or operator. This research work is therefore aimed at determining rational and durable combinations of materials and installation methods for areas in which water accumulates.

The BBSR has set up a research-support workgroup to assist the research contractor. STUVA has decades of experience in the field of sealing technology, and is able to contribute its specialist knowledge systematically in this context. Director Dr.-Ing. Roland Leucker was therefore pleased to agree to the BBSR's request for STUVA's involvement.
