Why Do Real Results Matter?
When home and building owners suffering from rising damp look for a solution, the question they most want answered is 'does it really work?' And that question is entirely fair. Dozens of different products and methods are promised on the damp-solution market; but how many of them actually deliver a lasting result? That is precisely why sharing real user experiences and concrete results matters so much.
In this article, we share the experiences of four different customers who solved their rising damp problem using Dryvatec HydroFix and DampStop products. Each story involves a different building type, a different severity of problem and a different application scenario. Our aim is to help you find an example similar to your own building and to form a realistic expectation.
Story 1: Historic Building Restoration in Istanbul
Building Details
- Location: Istanbul, Kadıköy
- Building type: A masonry apartment block from the 1940s, ground floor
- Wall material: Brick, 39 cm thick
- Affected area: 2 walls, 14 metres in total
- Damp height: Up to 120 cm in places
The Problem
The ground-floor flat had been struggling with rising damp for years. There were widespread damp stains, salt efflorescence and peeling paint in the lower parts of the walls. The owner had had it repainted 3 times in the last 5 years but had faced the same problem again each time. There was heavy mould growth in one corner of the living room and a damp smell had spread throughout the home.

The Application Process
The owner bought Dryvatec's 15-metre application kit. Following our application guide, he carried out the work himself. The total application time (including drilling, injection and DampStop) was about 8 hours over one weekend. Because of the old building's thick walls, the HydroFix consumption per hole was slightly above average; however, the contents of the kit were sufficient.
The Result (8 Weeks Later)
At an inspection 8 weeks after the HydroFix application, the damp stains had visibly faded and the salt formation had stopped. The musty smell had completely disappeared. By week 12 the wall had dried sufficiently and was replastered and repainted. Although 6 months had passed since painting, no peeling or staining had appeared.

Customer Review
"I'd been paying decorators for years. When they told me to apply HydroFix myself, I didn't believe it, but it really is very simple. I got everything done in one weekend. The walls have been spotless for 6 months now. I only wish I'd discovered it sooner."
— Ahmet B., Istanbul
Story 2: Detached House in Bursa
Building Details
- Location: Bursa, Nilüfer
- Building type: A detached house built in 2005
- Wall material: Pumice block, 25 cm thick
- Affected area: North façade, 8 metres
- Damp height: 60–80 cm
The Problem
Although it was a relatively new building, the inside of the wall on the north façade stayed permanently damp. The plaster had softened and the paint had blistered. There was a bedroom in this part of the house and the family was worried about the children's health. A quote obtained from an insulation firm involved excavating the external façade and re-waterproofing it, and a high cost was involved.
The Application Process
The owner first worked out the amount of material she needed by filling out our Request a Quote form. She ordered a 10-metre kit. Thanks to the porous structure of the pumice-block wall, the HydroFix fluid was absorbed quickly. The application took 5 hours in total.
The Result (6 Weeks Later)
The porous structure of the pumice-block wall allowed both good penetration of the HydroFix and rapid evaporation of the existing moisture. After 6 weeks the wall had completely dried. New plaster and paint were applied. There have been no problems for 4 months.
Customer Review
"We were about to have external insulation done — we've been spared a big expense. HydroFix turned out to be a far more economical and practical solution. The musty smell in the children's room is completely gone, and we're relaxed now."
— Elif K., Bursa
Story 3: Basement Conversion in Antalya
Building Details
- Location: Antalya, Muratpaşa
- Building type: An apartment block built in 1995, basement
- Wall material: Reinforced concrete + brick infill, 30 cm thick
- Affected area: 4 walls, 22 metres in total
- Damp height: 80–150 cm (basement level)
The Problem
The building owner was using the basement as a store, but belongings were being damaged by the constant damp. There were damp stains, salt deposits and widespread mould growth on almost all of the walls. The basement was spreading a damp smell throughout the whole building. The owner wanted to convert the basement into a usable space.
The Application Process
Because it was a large area of 22 metres, the owner carried out the application over two weekends. The first weekend was drilling and injection (about 10 hours), the second weekend the DampStop application and details (about 4 hours). The total application time was about 14 hours. Because the basement's ventilation was limited, the drying process was accelerated after the application with a portable dehumidifier.
The Result (12 Weeks Later)
The basement took a little longer to dry due to the limited ventilation. After 12 weeks the moisture readings had dropped to acceptable levels. The walls were plastered and painted. The basement is now used as a hobby room and additional storage. No sign of damp has been seen for 8 months.

Customer Review
"Our basement had been like a rubbish tip for years. After the HydroFix application, we started using it as a hobby room. The building's damp smell has completely gone too. Even our neighbours have noticed the difference."
— Mehmet T., Antalya
Story 4: Stone Building in Trabzon
Building Details
- Location: Trabzon, Ortahisar
- Building type: A stone building from the 1960s, ground floor
- Wall material: Natural stone (andesite), 50 cm thick
- Affected area: 3 walls, 18 metres in total
- Damp height: 100–140 cm
The Problem
Because of the Black Sea region's heavy rainfall pattern and high groundwater level, the ground floor of the stone building was facing a chronic damp problem. The thick stone walls were drawing up large amounts of water by capillary action. There was heavy salt build-up on the surface, erosion of the wall finish and constant mould growth. Due to the historic value of the building, destructive interventions were not wanted.
The Application Process
The 50 cm-thick stone wall required a different approach from the standard application. It was recommended to drill the holes from both sides (the inner and outer faces). This ensured that the HydroFix penetrated as far as the middle of the thick wall. Because of the irregular porous structure of the natural stone, some holes needed extra fluid. The application took 3 days in total.
The Result (16 Weeks Later)
The thick stone wall took slightly longer than expected to dry, about 16 weeks. But the results were striking: the salt formation had stopped completely and the damp stains had largely faded. Having come through the Black Sea winter without trouble, the walls were replastered and repainted in the spring. No sign of damp has been observed for 10 months. A permanent solution had been achieved without any damage to the historic fabric of the building.
Customer Review
"In our old stone house we used to fight the same battle every winter. HydroFix solved the problem without cutting into the wall or damaging the stone. It works even in a damp climate like Trabzon's — I can't believe it."
— Hasan Y., Trabzon
Comparison of Application Times
The application times of the four different projects vary according to the size and complexity of the building. To give a general summary, DIY application time usually depends on the following factors:
- Wall length: A 10-metre wall requires 5–8 hours of application time on average.
- Wall thickness: Thick walls require deeper holes and more HydroFix; the time increases.
- Wall material: Drilling into brick and pumice block is faster than into natural stone and concrete.
- Experience: The first application may be a little slower; from the second wall onwards the time shortens.
Drying time, on the other hand, is independent of application time and usually varies between 4 and 16 weeks. Drying is faster in well-ventilated areas.

Your Story Could Be Here Too
Every building is different, and every damp problem has its own dynamics. But as the stories above show, the HydroFix + DampStop system offers an effective solution for different building types, different wall materials and different damp levels. Whether it is a historic masonry building from the 1940s or a modern detached house built in the 2000s; whether the wall is brick, pumice block or natural stone; the HydroFix chemical barrier has produced effective results in every building type.
The common points that stand out in the stories above are these: all the customers had previously tried temporary solutions and failed. Methods such as repeated painting, waterproof coatings and ventilation had a masking effect in the short term, but the problem came back every time. After the HydroFix + DampStop application, no customer reported the problem recurring.
Another common point is the cost advantage. All four of our customers chose DIY application and saved considerably compared with professional alternatives. The application times remained reasonable even for inexperienced users. For detailed cost information, you can read our Damp Treatment Cost Guide article.
