With electrophysical masonry dehumidification, Drymat® fully complies with ÖNORM 3355 without any compromises. For you, this means the reassuring certainty that a technically and scientifically rigorously tested process is being used in your home. If you would like to be extra sure, you can also have the dehumidification and desalination process monitored by TÜV or a state-accredited building materials testing laboratory – for a small surcharge.

* The ÖNORM applies to measures on existing masonry that serve to prevent or limit the capillary rise of moisture. Only those groups of procedures are taken into account whose mode of action is generally recognised in the natural sciences and whose practical suitability has been proven. This ÖNORM is intended for everyone involved in the planning, tendering and supervision of such measures. The present Part 2 is to be applied only in conjunction with Parts 1 and 3 of this ÖNORM. For the regulation of works contracts, there is ÖNORM B 2202.
