Rising Damp is the name given to a form of dampness, which only comes from groundwater, moving up through the masonry pour structure. Usually, a DPC is fitted during construction.
Some remedial Rising Damp control measures:
Install a remedial chemical damp proof course to control the groundwater by controlling capillarity movement by fluid injected under pressure or cream injected into the mortar joints.
Install a remedial electro-osmotic system to control the rising groundwater by reversing its flow. The electro-osmotic system is fully reversible and suitable for historic buildings.
- Cut into the walls and install a physical damp proof course, but this could affect the building structure.
- Drain the ground around the property but may not be practical and needs to be monitored.
