Presentation of the project content
In developing our experimental guidelines, we focused on examining the properties of our manufactured products and distributed raw materials, exploring their advanced processing, and expanding their applications. Our starting point is the hydrophobic properties of the materials we produce and sell. But what does this mean in practice? How can hydrophobicity be measured, influenced, and utilized?
There are two well-known methods of hydrophobization (protecting materials from water damage):
1. During production – Hydrophobic additives are mixed directly into building materials to enhance water resistance. Our manufactured products are commonly used in this process.
2. Post-production surface treatment – Applied to existing materials to provide waterproofing protection.
The Importance of Hydrophobic Protection
Water is ever-present in our environment, both as liquid and vapor. While essential for life, its harmful effects—such as frost damage, corrosion, and biological growth—are well-documented. Wet materials conduct heat more effectively, contributing to energy loss, while damp surfaces promote the rapid growth of bacteria, viruses, moss, and fungi.
In our region, even newly constructed buildings quickly develop moss and fungal colonies. Night-time condensation provides the necessary moisture for these organisms to thrive. Beyond their unsightly appearance, their root-like structures penetrate building materials, degrading their integrity. Additionally, their airborne spores contribute to allergic respiratory diseases.
Since our company does not manufacture building materials, our focus is on surface protection solutions applied post-construction.
Challenges of Water Exposure in Buildings
Buildings face water infiltration from two primary sources:
- Groundwater (rising from below)
- Precipitation (rain and moisture from the air)
Because porous inorganic building materials absorb significant moisture, effective waterproofing is critical for durability. While protection against groundwater requires a complete waterproof barrier, precipitation protection can be achieved through three known methods:
1. Hydrophobic Impregnation – Allows ventilation while repelling water droplets without sealing material pores.
2. Impregnation – Partially seals pores while leaving the surface exposed.
3. Coatings – Penetrates material pores and forms a protective surface layer.
Connection to Our Research & Products
Our research aligns with these waterproofing solutions in several ways:
- Silicate-based impregnating agents can serve as binders for anti-corrosion coatings, waterproof layers in brick walls, and mold formation.
- Silicone rubber, known for its water-resistant properties, is also an effective binder for heat-resistant and insulating pastes.
These attributes allow for wide-ranging applications of our raw materials in the construction industry, supporting both structural longevity and environmental protection.
