Introduction
Damp problems can have different origins: condensation, leaks, or rising damp. Although the signs may look similar, each type requires a different approach. Applying a random solution without understanding the cause often leads to wasted time and money. Recognising the source of damp is therefore essential before deciding what method to use.
Main types of damp
Condensation
- Caused by excess indoor humidity.
- Appears as mould, water droplets, and black stains in poorly ventilated rooms.
Leaks and lateral penetration
- Caused by rainwater or faulty pipes.
- Stains often appear suddenly after heavy rain or in basements.
Rising damp
- Caused by water moving upward from the ground through capillary action.
- Appears at the base of walls with salt deposits and flaking finishes.
Why the cause matters
- Different signs, different sources
- Mould in corners is not the same as efflorescence at the base of walls.
- Avoiding ineffective solutions
- Dehumidifiers may reduce condensation but do nothing for rising damp.
- Anti-damp paint can mask stains but does not stop moisture movement.
- Targeting the problem directly
- Once the type of damp is clear, more suitable methods can be considered.
Options for rising damp specifically
- Breathable plasters → cosmetic improvement, allow evaporation.
- Electronic systems (ATE) → emit impulses to influence water movement in masonry.
- Geomagnetic systems (ATG) → use natural fields, autonomous and maintenance-free.
These options differ from measures aimed at condensation or leaks.
Conclusion
Understanding the cause of damp is the first step before choosing any solution. Condensation, leaks, and rising damp may appear similar but require different approaches. For capillary damp, specific methods and technologies such as ATE and ATG devices exist to target the issue without invasive work.
