Corrosion protection

in brickwork possibly  processed metals are indirectly included into the artificial electrical potential.They also deliver
moisture, which appear at their surface, to the negative pole of the field. The electro-osmosis also works as rust protection, e.g. with built-in water pipes, heating systems and other metal components.
The electro-osmosis method against corrosion has long been used in the construction of pipelines and ships.
