The Hidden Threat in Your Walls: Capillary Damp and Its Definitive Solution

You may have noticed that when you dip the edge of a paper towel into water, the water climbs upward, defying gravity, and dampens the entire towel. This physical principle is known as the "capillary effect" or capillarity. The same natural phenomenon occurs in our buildings and is called Capillary Damp (or Rising Damp).

Capillary damp is the upward migration of groundwater or moisture present in the soil through the porous structure of building materials. This structural problem, which takes time to detect but has a major impact, eventually turns into a stealthy threat to the integrity of your building.

Capillary Damp Formation in Walls Flaking and bubbling starting at the lower sections of walls are the most prominent warning signs of capillary damp.

Where is Capillary Damp Observed and Why is it Dangerous?

The risk of capillary damp is significantly high on ground floors, basement walls, masonry structures (stone, brick), old buildings, and historical buildings awaiting restoration.

Viewing this issue merely as an aesthetic flaw is a major mistake. The hazards capillary damp poses to structures and human health include:

  • Health Risks: It causes mold and fungal growth on interior surfaces. This poses respiratory hazards while also creating an unpleasant odor problem.
  • Aesthetic and Financial Damage: It causes plaster and paint coatings to bubble, leading to flaking and an unsightly appearance.
  • Structural Weakening: It shortens the lifespan of buildings by causing severe damage to primary structural materials, particularly concrete and steel reinforcement.
  • Energy Loss: It significantly reduces the energy efficiency of buildings by damaging the thermal insulation of the walls.
Capillary Damp Surface Damage Particularly on ground floors and masonry structures, moisture is the enemy of paint and plaster.

Forget Temporary Fixes: A Permanent Solution with Restora WP07

Capillary damp acts stealthily and slowly. Often, temporary fixes such as repainting or replastering the surface are used; however, since the source of the water lies inside, the problem will soon recur.

RESTORA WP07 Capillary Damp Prevention Material has been developed precisely for those seeking a permanent solution. This specialized product in cream form is injected inside the walls to establish a horizontal damp-proof barrier without damaging the porous structure of the surfaces.

The Secret: Advanced Silane Technology

Silane technology is an advanced chemical formulation used to impart water-repellent properties to construction chemicals. Silanes, which are silicone-based organic compounds, deeply penetrate the porous surfaces of building materials. They establish an impenetrable protective barrier against water at a microscopic level, permanently stopping the upward migration of moisture.

Restora WP07 Silane Technology The formula injected inside the wall using silane technology creates a barrier at a microscopic level.

How to Apply Restora WP07?

The application process is highly practical and effective. To create a professional damp-proof barrier step-by-step:

  • Drill holes along the wall horizontally at 10 cm intervals.
  • Ensure that the drilled holes are 5 cm shorter than the total thickness of the wall (to avoid drilling completely through the wall).
  • Completely clean out dust inside the holes using compressed air.
  • Inject Restora WP07 into the prepared holes with the aid of a specialized cartridge gun.
  • Ensure that no liquid contacts the surface for 24 hours post-application.
Restora WP07 Application Due to the specialized cartridge gun, the application is exceptionally clean, fast, and effective.

"The problem of capillary damp is solved not by repairing peeling plaster, but by blocking the rise of water inside the wall with a technological barrier."

Capillary damp will, over time, present severe systemic issues for your surfaces and structures. However, this is not inevitable. Thanks to Restora WP07 Capillary Damp Prevention Material, you can permanently put an end to this issue that rots your buildings from the inside out, securing healthy and safe living environments.
