Aarsleff CIPP Lining is a method well suited for renewal of vertical kitchen downpipes with laterals and water traps, as this cost saving method does not only reduce the time that it takes to carry out a renewal project, it also minimises the need for removal and demolition.In many old buildings, especially in residential buildings, the kitchen downpipes are often in very bad condition which can cause odour nuisance. When we are to renew kitchen downpipes, we always begin the work with cleaning the kitchen downpipes so that they get back their initial cross sectional area. The cleaning takes place with CCTV monitoring, and in this way we record and document the condition of the kitchen downpipes. During the cleaning, we remove rust scales that cover corrosion holes.

With Aarsleff CIPP Lining, which consists of several layers of acid-proof polyester felt impregnated with resin, we are able to renew vertical toilet downpipes, including built-in downpipes, with laterals and water traps quickly and efficiently. Aarsleff CIPP Lining reduces the need for demolition and thereby the time that it takes to carry out a renewal project. In short, this means improved finances and less inconvenience to the residents and users of a building.Irrespective of the extent of a renewal project, we always start the work with a careful planning phase and we always work according to a well-organised plan that ensures a high level of information to the residents and users of a building.
