Rising damp is the capillary action of water rising and flowing along narrow spaces, countering to the forces of gravity. Bricks and mortar can be porous and contain many fine capillaries, through which water can rise. The groundwater that rises up through the wall often contains salts, minerals and nitrates that can contaminate plaster and cause lasting decorative spoilage.

We use water-based silicone cream that spreads through, and bonds with, sand/cement mortar. Any continuous sand/cement mortar line that has been properly treated with becomes a damp-proof course. Due to the fact that we use high strength creams, such as Dryzone, they deliver 5 times more active ingredient to a wall, over a wider area than other low strength competitors, making our damp proof course longer lasting and more effective.

We drill holes in to the first continuous mortar course that is at least 150mm above ground level. On a standard brick wall, these holes are drilled 90% into the width of the wall at 120mm intervals.

The Dryzone cream is introduced into the pre-drilled holes. This is usually done using a professional applicator gun.. Once the cream has been successfully applied, we move on to the next stage of the treatment.

We then install a damp proof membrane. This barrier treatment is a quick and effective method which provides a complete barrier from any damp left in the wall. We can then plasterboard the walls and plaster skim. 

Using this method means that the plaster can dry within a couple of days, ready for decoration.
