Frequently Asked Question
How is rising damp rectified and what does the process involve?
Rising damp is rectified by injecting waterproof chemicals into wall joints to create a moisture barrier, followed by repairs to internal finishes.
Rising damp rectification typically involves creating or restoring a barrier between the ground moisture and the building materials above. The most common modern approach is injection damp-proofing, where a waterproof chemical is injected horizontally into the mortar joints of the affected wall, usually around 150mm above ground level. This creates a continuous moisture barrier that prevents capillary action from drawing water upward. FeaturePoint Constructions assesses each property individually to determine the most appropriate method, as factors like wall construction, existing DPC condition, and property age all influence the solution.
The rectification process begins with thorough inspection and diagnosis to establish the exact extent of rising damp and any underlying causes. Once a solution is determined, damaged internal finishes like plaster or render may need to be removed to access the walls properly. After the damp-proofing treatment is applied and has cured (usually several weeks), internal surfaces are carefully restored. This ensures the moisture barrier is effective and new finishes won't trap residual dampness. In some cases, additional measures like improving drainage around foundations or installing ventilation may be recommended to address the root cause and prevent recurrence.
