CONSTRUCTION CHEMICALS

Perfect protection for buildings

Moisture in buildings and construction materials causes annual economic losses worth billions. However, most of the damage could be avoided, since modern chemistry has a remedy for moisture in buildings. RUDOLF develops and produces products and additives for protecting buildings and construction materials from water.

Additives for paste like masonry coatings

Due to their pore and capillary structure, mineral backgrounds take up moisture when in contact with water. Taken-up water can cause damage. In addition, disintegrating pollutants and micro-organisms penetrate into the building fabric together with the water. A value-maintaining preservation of structures is achieved by high-performance coating systems. These are, first of all, paints and plasters which resist weather, absorb as little water as possible and maintain the breathability of masonry. Under the name RUCOSIL RUDOLF offers waterproofing additives that confer optimum protection. Silicone resin binders for paints and plasters as well as silicone waterproofing additives for the most diverse types of coatings increase water repellency and maintain or even improve water vapour permeability.

Moisture in masonry, bridges or other architectural buildings is one of the essential factors of structural damage. A precautionary measure against damage caused by moisture is the impregnation with silicones. Silicones attach particularly tight to mineral substrates and can be effective for decades. Silicone impregnations are colourless, do not form films, prevent the penetration of water and maintain the water vapour permeability of construction materials. Silanes, above all, readily spread on surfaces and penetrate very well into the substrate. Silicones are irreplaceable for damp proofing masonry by means of chemical injection. Here silicone impregnating agents are injected into damp walls via boreholes. A hydrophobic zone forms - the capillary rising damp in a wall is stopped and the masonry can dry. Under the trade name RUCOSAN RUDOLF produces construction chemicals for protecting and restoring buildings.

All natural stones, but also unglazed artificial stones or fine stoneware are more or less porous. Absorbent surfaces, however, take up liquids that carry over soil and stain-forming substances, such as coffee, tea, wine, oil, fat, etc. into the coverage. The liquids cause permanent discolouration and the otherwise clean surface looks unsightly. Under the trade name RUCOTEC RUDOLF develops and produces stain-repellent fluorocarbon-based impregnations for the oil, soil and water-repellent finishing of stone surfaces.
