Heritage Rising Damp Restoration

Over the past 20 years BRW Remedial has been involved with Significant Heritage projects though out Sydney. Specialising in Westox Chemical Injection and Cocoon Systems.

Salt Damp is a significant issue in heritage buildings. In modern buildings to prevent salt damp it has become legislation to place an impermeable barrier at the base of the wall just above ground level.

Most properties use a thick black plastic sheet to create the damp proof course. Some of our early buildings used lead sheets, bitumen based mortars, overlapping roofing slates and glazed ceramic tiles/brick to create the barrier. Moreover, some of these remain effective today.

The damage caused by salt damp to the existing masonry and bricks on a heritage building can be costly and extensive. If left for an extended period both the moisture and salts will cause long-term decay to your walls. The mortar will fret and crumble away, and the face of the stones/ bricks will rupture and begin to erode. This damage can leave the building structurally vulnerable and visually unappealing.

Westox Cocoon is the perfect choice for Halting Deterioration

Cocoon works by drawing the salt out of the masonry it is applied to. Cocoon is spread in a 10mm thick layer where it slowly releases water into the masonry to place the build up of salts in the surface of the wall into solution.
As the cocoon dries, the water containing the salts is drawn into it. The cocoon is then removed, along with the salt.
