1. Moisture problem: rising damp
What is rising damp?
Rising damp occurs when ground moisture rises through the foundation or walls. This often happens because there is no or an outdated damp-proof course present. The moisture then slowly rises higher in the wall, especially in basements and on the ground floor.
Because ground moisture often contains minerals and salts, visible white efflorescence (wall salts or saltpeter), peeling plasterwork, and a musty smell occur. Over time, this can lead to structural damage to walls, floors, and paint finishes.
How do you recognize rising damp?
- Damp spots at the bottom of walls
- Peeling paint or loose wallpaper
- Salt rings or a white powdery layer on the wall
- Mold Formation and Musty Odor
How to Treat Rising Damp?
At Solusio, we always choose an effective and sustainable treatment tailored to your home. Rising damp can be treated in various ways, depending on the severity and cause of the problem.
Our solutions for rising damp:
- Wall injection: We apply a moisture-resistant gel in the wall that forms a waterproof barrier and stops further rising.
- Wall Underpinning or damp-proof course: in older homes without a damp-proof course, we install a new, permanent separation layer that blocks ground moisture.
- Cavity wall repair: we repair damaged joints or insulation materials that cause moisture conduction, allowing walls to breathe again.
Solusio detects the cause of the moisture with a free moisture diagnosis. This way, we know exactly where the problem starts and can solve it sustainably.

2. Moisture problem: condensation and mold formation
What is Condensation?
Condensation occurs in areas where the humidity is too high . When warm, humid air cannot escape sufficiently, for example due to poor ventilation, the water vapor condenses on cold surfaces such as walls, windows, and ceilings.
If these surfaces remain damp for a long time, mold and musty odors. Especially bathrooms, kitchens, and bedrooms are susceptible to this problem.
Typical symptoms of condensation and mold:
- Dark or black mold spots on walls and ceilings
- Affected paint or wallpaper
- Moist windows or condensation droplets
- Poor air quality and respiratory complaints
How to Treat Condensation and Mold?
At Solusio, we address not only the visible damage but especially the underlying cause.
Our most applied solutions are:
- Installation of a ventilation system that removes humid air and brings in fresh air.
- Repair of thermal bridges and insulation, so walls no longer act as condensation surfaces.
With this approach, we restore the air balance in your home and prevent mold or moisture from forming again.

3. Moisture problem: a damp basement
How does a damp basement occur?
A damp basement can have various causes:
- Seepage water penetrating through walls or floor
- Groundwater pressing through due to pressure against the foundation
- Leaks or faulty drainage
- Poor sealing or outdated waterproofing
- Condensation due to poor ventilation
A basement is part of the foundation of your home and thus plays a crucial role in stability and indoor climate. When moisture accumulates, it can not only affect the walls but also cause rising damp in the rest of the house.
How Do We Treat a Damp Basement?
Our experts always look for the real cause of the problem. Depending on the situation, we apply one or more of these solutions:
- Wall injection: stops rising damp at the base.
- Basement sealing: we apply waterproof cement layers or coatings that completely seal the basement against penetrating moisture.
- Basement drainage: we install a drainage system that collects and drains water, ideal for high groundwater pressure.
With our specialized approach, you get a dry, healthy, and usable basement space. Contact us for tailored advice.
4. Moisture problem: penetrating damp
What is Rising Damp?
Penetrating damp occurs when rainwater penetrates the exterior walls and thus makes the interior walls damp . Especially with facades that are porous, damaged, or poorly maintained, rainwater can easily seep in.
When the facade cannot drain or dry out the moisture quickly enough, the walls remain wet for a long time. This leads to:
- damp spots on interior walls,
- peeling paint or plaster,
- mold formation,
- and even damage to the masonry.
How do we treat penetrating damp?
At Solusio, we ensure lasting facade protection with the following treatments:
- Hydrophobic treatment (facade impregnation): we apply a transparent, water-repellent layer that keeps rain out but allows the wall to breathe.
- Moisture-resistant paint: protects and beautifies the facade at the same time.
- New facade cladding: ideal for severely damaged walls or when renovating older facades.
Thanks to these techniques, your facade remains dry, clean, and durably protected against rain and wind.
