DBV Code of Practice 'Injection hose systems and swellable fillers for construction joints' - Additional applications

摘要

The new December 2020 version of the DBV Code of Practice on "injection hose systems and swellable fillers for construction joints" [1] again aims at planners, contracting parties and building contractors. It provides information on planning and the invitation to tender, work process planning and the material selection for injection hose systems and swellable joint fillers and provides application guidance in respect of execution and quality assurance and gives examples concerning the documentation of the works performed. Injected hose systems and swellable joint fillers only bind partially to the structural concrete of the second concreting section. The crucial requirement for the successfully sealing effect of an injection hose system after an injection, among others, is the surface contact of the joint filler in the construction joint. In this regard, amendments were added for a permissible joint roughness in the immediate contact area of the hoses.
