Maintenance joint

Definition to DIN 52 460: A maintenance joint is a joint exposed to strong chemical and/or physical influences, the sealant of which is inspected at regular intervals and which has to be renewed if necessary to prevent consequential damage. There are limits to the stability of sealants which are usually not reached or indeed exceeded in normal use.

Please note: The maintenance joint is not covered by the warranty provided for usual jointing work. As a consequence, a joint must already have been designated and defined as a maintenance joint before the work is carried out. It must already be defined in the quotation which joint is to be considered as maintenance joint. It is not possible to define maintenance joints after the work has been carried out.
