Magnetic DPCs have been around in Europe for some time since the 1980s-1990s. Their main benefit is their non-invasive nature, being suitable for any building including historic and listed buildings.
They are electronic devices resembling a lamp shade being installed onto the ceiling of the ground floor or basement, usually in service areas such as pantries, cupboards or walking closets. They are not dehumidifiers, they do not collect water. They perform a dual function:
- Wall dehydration function: In the short term they permanently dry out the building fabric by reducing the capillary forces inside the walls.
- DPC function: in the long run they protect the building from the re-occurance of rising damp by preventing the rebonding of water molecules onto the capillary walls.
They are available in various sizes, depending on the thickness of the walls and area to be covered – most often one unit per building is enough. Several units can be combined to cover larger areas, if necessary.
Here are some of our UK installations showing the various sized units fitted in a number of different buildings.
Magnetic DPCs come in several sizes. The largest system can dehydrate buildings of over 1,000 m2 ground floor footprint. Typically, only one DPC system is needed per building, but multiple units can be combined to dehydrate larger or odd-shaped buildings.
The dehydration systems are manufactured to very high technical standards and they undergo strict quality checks.
