Gravity Damp Course or Damp-Course Fluid (Damp Proofing Liquid) is a product on the base of Siloxane, which penetrates the wet walls. After the penetration into the Brickwork, Damp-Course Fluid reacts with existing minerals, creating durable wet layer, protecting the wall from moisture.

Gravity Feed Method (Gravity Damp Course, or Damp Proofing Liquid) was used since 1950-s – that time the product was injected with vortexes. This method was practically the only one and the most effective treatment of Rising Damp till 2000-s – when the British Company Safeguard Chemicals invented their revolutionary cream DRYZONE – Damp Proofing Cream. After this invention Damp Proofing Liquid is losing its popularity – however, it is still used in some situations.

Damp Proofing

Damp Proofing Liquid is great for a large amount of work – mostly because it’s cheaper price. Another situation where Damp Proofing Liquid is used – when the Brickwork has to be rendered after the injection – otherwise in the process of drilling (which has to be 45 degrees) there is a risk of chipping the brick. More than that – patched holes don’t improve the overall view of the injected area.


However – Damp Proofing Liquid is as effective as other, more advanced methods of Damp Proofing and still commonly used on the construction sites or outdoor settings.
