DAMP PROOFING SOLUTIONS

INSTALLATION OF DAMP-PROOF COURSE

 

  • Holes are drilled in the mortar of the bricks at a specified height
  • Damp proofing material is then injected into the holes

 

A water-based silicone injection is considered the most effective damp proof course at preventing the rise of moisture through walls.


Re-plastering is often required after the insertion of a damp-proof course. New wall plaster will then prevent the migration of damp and salts from the wall to the internal wall decoration.

RISING DAMP

Rising damp refers to water travelling through porous building materials that are in contact with the ground. This causes the wall to draw water from the ground, which in turn evaporates into the atmosphere. This pattern continues, until the water reaches a height where it can no longer evaporate, meaning dampness will occur and remain in the wall.

THE ELECTRO OSMOTIC DAMP PROOFING SYSTEM

The Electro Osmotic system is increasingly accepted as an alternative to fluids and physical damp course. This system rising damp by using a low-voltage electrical current to create an electric field that pushes moisture back down into the ground. It is unique in the way it uses titanium and platinum group elements to carry all positive voltages.


Once a small voltage has been applied to the titanium via the power unit, the titanium wire in contact with the wall and anode sections will immediately become a conductor. Due to the ability to continually conduct electricity, a very rapid build-up in the wall is possible. 


Eventually, an insoluble film of titanium dioxide will build up at the point of contact between the titanium and wall. Once this film is established, the titanium will mostly stop conducting electricity further. As long as the voltage is applied regularly, corrosion ceases to be an issue. The anodes will naturally continue to conduct and maintain the wall potential.


To summarise, this damp proofing system is virtually self-healing. Any scratching to the titanium will simply see it form another protective skin. This type of system is often used on flint walls and listed buildings.
