Electro-osmosis damp proofing is a method used to combat rising damp in buildings by reversing the natural flow of water through capillary action in porous materials like brick or stone. This technique involves installing titanium or graphite anodes into the affected walls and applying a low-voltage electric current. The current repels water molecules away from the internal wall structure toward the ground, effectively drying out the walls over time. Electro-osmosis is a minimally invasive and eco-friendly solution, often chosen for historic buildings where traditional damp proofing methods may be unsuitable.
