Rising Damp vs. Condensation

One of the fundamental points of confusion on the subject of dampness is the confusion between rising damp and condensation. Recent research on condensation has finally clarified the differences between these two phenomena. Rising Damp vs. Condensation – Simple, Non-Technical…

Breathability

The concept of breathability is paramount in building conservation. Breathability means the fabric of old building needs to be open-pore or permeable to moisture. This way water vapors can penetrate the fabric and moisture can evaporate out from the fabric…

Magnetic DPC Theory and Fundamentals

HistoryObserving these effects goes back 30-40 years. Skepticism, some commercial interests but especially missing research about the wall phenomena never allowed for these systems to become mainstream. With the latest ongoing research answering many questions about the nature of moisture…

Electro-Hygro-Thermal Changes in Damp Masonry

Humidity and temperature variations in buildings - also known as hygro-thermal changes - are well known among building professionals. Heating creates evaporation, while cooling often results in condensation. Because air always contains quite significant amounts of humidity in vapor form…

Research & Development

Research & Development Phases The overall development of the magnetic DPC technology followed a top-down approach in two main stages:Stage 1: Building Level ResearchBecause the objective was to non-invasive;y handle rising damp at building-level, the initial research focused on the "big…

Research Videos

A significant part of our activity is hands-on research. We research the main drivers behind the movement of moisture in porous materials, the various drivers behind rising damp, the electrical aspect of moisture movement, building materials etc. Some of these findings…

Capillary Effect vs Evaporation from the Soil

After doing several experiments on the topic of water absorption into porous bricks, and comparing and cross-referencing the results, we made an interesting discovery about the mechanism of fast vs slow wetting.Experimental SetupExperiment 1: we applied water directly at the…

Rising Damp Recreated in a Lab

Recreating Rising Damp in the LabRising damp can be recreated in a lab under "artificial" conditions very easily.We used some common "old-style" porous bricks, purchased from a brick factory. We put it in a plastic tray, added some water to…

Controlling Moisture with Non-Invasive Means

The fact that certain wave forms and frequencies affect the movement of moisture in porous building materials, can open the door to new, non-invasive technologies in moisture control - both drying and wetting - applicable to a wide variety of fields,…

Humidity vs. Voltage Changes

Dumping water at the base of a brick sitting in a tray - as we have found out - creates a very fast capillary rise, generating a lot of change quickly. Because most old houses are not sitting in water…
