SYSTEM OF PRODUCTS FOR DEHUMIDIFYING, DESALIENATING AND ANTI-FUNGAL TREATMENT OF WALLS AND MINERAL PLASTERS
Problems related with the presence of water and moisture within building walls are phenomena commonly found particularly in old buildings, the foundations of which were not equipped with horizontal and vertical anti-moisture and waterproof insulations.
The innovative HERMON technology is used to for drying, consolidation and hydrophobisation of old, wet walls, concrete and aerated concrete, as well as removal of algae fungi and other microorganisms.
HERMON comes in the form of water solutions of several substances and chemical compounds. It works by using the water inside the wall as a carrier and conductor for the preparation. This significantly differentiates HERMON from other, popular hydrophobic agents, which, in most cases, operate on the surface with limited penetration depth.
- does not require power tool use (drilling, hacking), but only the application of HERMON on a wall.
- less labour-intensive than other commonly used methods. As a result, this technology is far more competitive. , which differentiates it from equipping existing walls with horizontal insulation by means of joint cutting or auxiliary hole drilling in order to perform resin injections.
- the effects are visible much sooner than in the case of the abovementioned technologies.
- universality of effects An equally important thing as the lack of need for cutting or drilling into walls, are the universal effects of the preparation. It is mainly due to the fact that HERMON is used for dehumidifying, as well as desalinating and fungal removal. In the case of other technologies, it is necessary to use several agents, with a very narrow scope of action.
The application of the complete wall hydrophobisation technology requires the application of four agents: HERMON I, HERMON II, HERMON III and HERMON IV, that vary in the active ingredient and number of particular solvent content. Each application corresponds to a phase of the drying and hydrophobisation processes.
Phase I includes the construction of new crystalline structures around fine microorganism particles inside the wall. HERMON I applied on a wall, penetrates its surface, using capillaries inside the concrete or brick structure. After dissolution in water, it surrounds grains of micro-fauna and micro-flora, causing rapid growth in their volume. A consequence of the above mineralization process is the increase of pressure inside the wall, which results in the displacement of water from its structure. The external indication is the liquefying of large amounts of water on the wall surface. The displacement of water from the wall interior is more intensive, the more moisture was present.
Phase II is characterized by a slowing down of the development of new grain nuclei crystallization, which prohibits blocking of water flow between wall particles. Used for this purpose, HERMON II causes partial dissolution of joints, both newly created and already existing grains.
Phase III. Application of HERMON III further reduces the pace of crystallization, reducing the internal stress of the walls. This process is intended to restore balance wherein the slow growth of grains will be connected with capillaries transformation into capillary tubes, being the condition of proper operation and use of the regenerated wall.
Phase IV is securing the dried wall from degradation. HERMON IV applied on a wall, produces a firmly adjacent coating, which is characterized by high mechanical strength and diffusion properties. Thanks to that, the wall can "breathe", i.e. remove moisture from the inside into the environment, at the same time protecting the wall against external factors. HERMON IV, strengthens and consolidates the wall structure, provides hydrophobic qualities (material absorbability decreases on average by 100%), and protects against biological corrosion and moisture.
