What is Rising Damp?

Rising damp occurs when moisture from the ground travels upward through your home’s walls via tiny pores and capillaries in building materials like brick and mortar. Similar to how a sponge absorbs water, your walls naturally draw moisture from wet soil through capillary action, causing water to climb against gravity until it reaches a point where evaporation balances absorption. This process typically creates a visible tide mark up to one meter high, often accompanied by white salt deposits that damage plaster and paintwork. Left untreated, rising damp can severely compromise timber floors and structural elements, leading to rot, fungal growth, and potential collapse of floor joists that rest directly in damp masonry.

Bridging of DPC

Damp-proof course (DPC) bridging happens when water finds alternative pathways around your existing moisture barrier, rendering it completely ineffective. The most frequent cause is external ground levels that sit higher than the DPC line, allowing water to simply bypass the protective barrier and enter walls above it. Internal factors like render, plaster, or mortar that extends below the DPC level can also create bridges, while debris buildup against walls provides another route for moisture infiltration. Even the most effective damp-proof course becomes useless when water can circumvent it, making proper installation and maintenance of clear pathways essential for long-term moisture protection.

Treating Rising Damp

Modern damp proofing solutions focus on creating effective moisture barriers without major structural disruption to your property. Chemical injection involves introducing specialized damp-proofing compounds directly into the wall through precisely drilled holes, creating an impermeable horizontal barrier that blocks capillary water movement. For thicker stone walls or complex structures, we may recommend mortar injection or electro-osmosis systems that actively repel moisture using controlled electrical fields. The most suitable treatment depends on your wall construction, severity of the problem, and building age, with our expert assessment determining the most cost-effective approach that provides long-lasting protection for your Melbourne home.

Re-plastering After DPC Installation

Installing a damp-proof course is only the first step in comprehensive moisture treatment, as existing walls will retain significant residual dampness and harmful salt contamina
