Effective way of drying walls and foundations
Problems with the presence of water and moisture in buildings are commonplace especially in old buildings, whose foundations are devoid of horizontal and vertical damp insulation and waterproofing.
Innovative dryPROTECH technology is used to dry, consolidate and hydrophobise old, wet walss made of brick, concrete and aerated concrete and to remove algae, fungus and other microorganisms.
The main components of the system are HERMON agents in the form of aqueous solutions. The agents use the water contained within the wall as a carrier. The product is fundamentally different from other popular hydrophobic agents, which in most cases act on the surface or depth of penetration (penetration into the surface) is limited.
- No need for mechanical actions (drilling, chipping), but only application of HERMON agents to the surface.
- Less labour-intensive than other commonly-used methods. It fundamentally differs from horizontal insulation created by undercutting the welds or drilling holes to perform the injection.
- Effects are noticeably faster than in the case of technologies mentioned above.
- Versatility of the agent's effects. The product removes both the effects of dampness, salinity, and mould. In the case of other technologies it is necessary to use several products, each of which has only a narrow range of application.
Mechanism of action:
The use of full technology requires the application of four agents named HERMON I, HERMON II, HERMON III and HERMON IV. The application of each of them corresponds to the individual phases of the drying and hydrophobisation process. Phase I builds new crystalline structures. HERMON I penetrates inside the wall, using capillaries inside the concrete or brick structure. The accompanying increase in pressure causes displacement of water from its structure. On the outside, this is manifested by the condensation of large amounts of water on the surface of the wall, which is the more intense, the more damp the wall. Phase II is characterised by a slowdown of the process, so the flow of water between the wall elements is not blocked. Application of HERMON III (phase III) causes a further reduction of the crystallization rate, thus reducing the internal stresses in the wall. This process aims to bring about a state of balance. Phase IV protects the dried wall against re-degradation. HERMON IV applied to the surface has a "breathable" coating that removes moisture from the wall to the outside and protects it against external influences. Thanks to its properties, HERMON IV strengthens and consolidates the structure of the wall, hydrophobises it (the absorption of the wall material is greatly reduced) and protects against biological corrosion (mould, algae) and moisture.
In the case of bare concrete or other surfaces requiring no aesthetic finish, the work is completed. But for surfaces that need smoothing and painting (e.g. indoor walls, façades) we use „SUPER BIAŁA Cement Mortar” to smooth the surface and then paint it with SILANIT paint.
SUPER BIAŁA Cement Mortar is designed for thin-layer plasters on walls and ceilings, as well as for other refurbishing, finishing and decorating works indoor and outdoor. Due to its excellent properties it is suitable for damp areas. It bonds well to concrete, cement and cement-lime surfaces. Uses as part of the dryPROTECH system, it does not impede the removal of residual moisture from the inside of the wall by HERMON agents.
SILANIT W and SILANIT 100 are mineral paints intended for painting cement and cement-lime plasters, base plasters, brick and concrete. The basic use of paint is damp spaces, but it can also be used on façades of buildings covered with mineral plasters. Due to the well-chosen ingredients, these products provide mould protection in new premises such as dairies, breweries, distilleries, warehouses as well as the renovation of damp, moulded walls in old buildings, also of historical character. Their use as part of the dryPROTECH system provides a permanent protection of the dried wall for many years.
