In the sealing of media lines in buildings there is an endless number of applications and requirements. Often we have to take already existing circumstances into account. There isn't always a standard solution. Instead, an individual solution has to be found and implemented. We work with our customers to develop the fitting seals that meet the technical requirements in all fields. We support you in your project from planning to realisation. Regardless of whether the job is a complete renovation, multi-line feed-throughs for a variety of media with unusual diameters or an extraordinary requirement in terms of building systems, Hauff-Technik always has the right system and the right solution.
