Internally, the DPC system consists of a system of receiving and transmitting antennas, and is composed of the following modules:
To understand how the dehydration system works, some basic understanding of certain physical phenomena is required. For easier understanding of the key concepts, the explanations in this section have been deliberately kept simple and the complex scientific terminology has been simplified.
Most building materials — including brick, cement, sand, quartz, granite, sandstone, clay, glass etc. — are silicate based, consisting mainly of silicon and oxygen. Due to their molecular structure (one silicon atom surrounded by several negatively charged oxygen atoms), building materials have a negative surface charge. (–)
Water (H2O), is a two-pole molecule, with one negative (the O–) and one positive (H2+) side. This structural arrangement makes water molecules behave like tiny liquid magnets which can be influenced by external fields.
So fundamentally all wall surfaces are negatively charged, while "the larger" part of the water molecules are positively charged.
From elementary physics we know that opposite charges attract each other and similar charges repel each other. The negative wall surface attracts the positive end of the water molecules and this is capillary attraction. This is one of the fundamental mechanisms behind rising damp.
Wall Dehydration Effect
The dehydration system outputs tiny pulses on well-defined frequencies (30 Mhz - 3 Ghz frequency band) throughout the footprint of the building. These pulses penetrate the surrounding walls and reduce the capillary adhesion forces between the wall and water molecules. As a result the wall capillaries can "let go" of the water, which under its own weight (gravitational pull) sinks back into the ground, resulting in the dehydration of the building.
The results are permanent as long as the DPC system is kept in the building.
Long-term the system prevents the re-bonding of water molecules onto the capillary walls, acting as a "wireless" damp proof course keeping the building dry for decades.
