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…

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…

Step 1: Damp Proof Courses

The Role of a Damp Proof CourseThe primary role of a damp proof course (DPC) is to be a VAPOR BARRIER from the ground to prevent or minimize the excessive evaporation of water into the wall fabric, which over time develops…

“Water in” vs. “Water out”

The amount of water inside damp walls - and weather a wall is getting damper or drier at any point - is determined by the balance of two factors: Water in: how much water being absorbed into the building fabric…

Pressure Driven Flows, The Role of Heating

The Effect of HeatingIn addition to electrokinetic short-range forces, some external factors - such as temperature and pressure - also affect the movement of moisture inside capillaries.The positive effect of slow, steady heating in old buildings is well known. Heating…
