Frequently Asked Question
What causes rising damp and can it be prevented in new construction?
Rising damp results from missing or failed damp-proof courses; modern construction prevents it through proper DPC installation and drainage management.
Rising damp is caused by the absence or failure of a damp-proof course (DPC), combined with the natural capillary properties of building materials and the presence of ground moisture. In older Port Melbourne properties, many homes were built before damp-proof courses became standard practice, leaving them vulnerable. Even where a DPC exists, it can fail over time due to cracks in the wall, ground levels being raised above the original DPC height, or simply deterioration from age and environmental factors.
In new construction, rising damp is largely preventable through modern building practices and compliance with building codes. A properly installed damp-proof course, usually made from bitumen-based materials or plastic membranes, is placed horizontally within the wall during construction. Ground drainage must also be carefully managed to direct water away from foundations. Additionally, modern materials like cavity wall construction provide better resistance to moisture ingress. However, even with these precautions, long-term maintenance is essential. If you're building a new home in Port Melbourne or undertaking substantial renovations, FeaturePoint Constructions ensures all moisture barriers are installed to current standards, protecting your investment against future rising damp problems.
