Damp Proofing After Subsidence in Dorset
Subsidence damage often creates pathways for moisture to enter your Dorset property. Cracks in walls, failed damp proof courses displaced by movement, and compromised drainage all contribute to damp problems following subsidence. Our specialist damp proofing service addresses these issues as part of a complete subsidence repair programme.
We install chemical damp proof courses, membrane systems, and remedial tanking to tackle rising damp, penetrating damp, and condensation issues caused or worsened by structural movement. Every installation is preceded by a thorough damp survey to identify the type and source of moisture.
Addressing damp after subsidence is essential — not just for comfort and health, but because ongoing moisture can re-soften ground beneath foundations and potentially trigger further movement. Our integrated approach treats both the structural and damp issues together.

Frequently Asked Questions
Does subsidence cause damp?
Subsidence itself doesn't cause damp, but the structural damage it creates — cracks, displaced DPCs, and broken drains — allows moisture to enter your property. Addressing both issues together is essential for a lasting repair.
What is a chemical damp proof course?
A chemical DPC is a waterproof barrier injected into the base of walls to prevent moisture rising from the ground. It's the most common solution for rising damp and replaces the original DPC that may have been compromised by subsidence movement.
How do I know if I have damp after subsidence?
Look for tide marks on walls, peeling wallpaper, musty smells, black mould, and salt deposits on masonry. These often appear after subsidence repairs if damp hasn't been separately addressed. A professional damp survey will confirm the diagnosis.
How long does damp proofing take?
A chemical DPC installation typically takes one to two days for a standard property. More comprehensive damp proofing involving membranes and tanking may take longer. We always specify timescales in our quotation.
Will damp proofing stop mould?
Properly addressing the source of damp will prevent mould from returning. We also treat existing mould and advise on ventilation improvements to maintain a healthy indoor environment.
Is damp proofing guaranteed?
Yes, all our damp proofing work comes with comprehensive guarantees — typically 20-30 years for chemical DPC installations. Full documentation is provided for your records.
