The method FLICK uses to treat Rising Damp - See Figure B

 

To halt rising damp, a chemical damp course is injected at a pressure of between 170 kPa and 350 kPa into holes drilled horizontally at 110mm centres into brickwork in a continuous line on or as close to the internal floor level, or external soil level, which ever is the greater. This method has proved successful for over 50 years. 

Flick have been using this method successfully for 40 years and it has been approved by the British Board of Agrement. BS 6576: 1985 Code of practice for diagnosis of rising damp in walls of buildings and installation of chemical damp-proof courses. 

Some Causes for Rising Damp - See Figure A

 

  • Deterioration of the original damp course. Early Buildings used bitumen-based materials. Many newer properties have PVC plastic damp courses.
  • The damp course is incorrectly positioned.
  • The damp course has been omitted.
  • The damp course has been breached.

 

Where the damp proof course is damaged, bridged or omitted the damp continues to rise and evaporate on the surface leaving behind soluble salts which deteriorate the plaster and cause the paint to blister. The salts continue to absorb moisture from the atmosphere unless treatment is undertaken and the contaminated plaster removed. 


 

 

Rising Damp originates from the moisture, which is always present in the soil, rising up the walls of the building. A high Water Table will not in itself cause Rising Damp. There must always be a Contributing factor. 


Moisture from the soil rises by capillary action through the porous mortar and brickwork. To prevent the moisture damaging the plaster and paintwork the builder inserts a plastic damp course.
