SiSiB produces a series of silanes, siloxanes and emulsions, which can be used for the waterproof treatment of various substrates: concrete, slate, sandstone, limestone and marble, bricks and tiles.

All building materials are exposed to damaging environments, from water ingression to high alkalinity erosion. SiSiB produces a series of silanes, siloxanes and emulsions, which can be used for the waterproof treatment of various substrates: concrete, slate, sandstone, limestone and marble, bricks and tiles.

Silane and siloxane have excellent water-repellent properties, can penetrate and form a protective layer in the substrate a few millimeters deep, and will not significantly reduce the permeability of water vapor. Other hydrophobic treatments may block or seal pores and capillaries, resulting in less vapor transmission and loss of performance after surface abrasion. The hydrophobic treatment of silicone is durable, because silicones have good resistance to external influences, such as ultraviolet radiation, thermal stress, corrosive substances and microbes. This is due to extremely stable covalent bonds between the silane and the silicate matrix of the pores and capillary walls in the concrete.

Silanes used for concrete waterproofing must penetrate well into relatively dense concrete and resist the high alkalinity degradation in new concrete. The purpose of hydrophobic impregnation is to prevent the absorption of water and corrosive substances dissolved in the capillaries by using a colorless non-film-forming agent, thereby protecting the exposed external walls from moisture and related damage. Because the capillaries remain open, the substrate maintains its vapor permeability.
