Silane is a penetrating impregnating coating with excellent performance, which gives the micro-structure of concrete a long-term hydrophobicity, and maintains the function of breathing and air permeability, significantly reduces the invasion of water and harmful chloride ions, ensures the concrete structure from corrosion, and improves the durability of concrete.

Silane has a small molecular structure. The interaction between the capillary wall of deep permeable concrete and hydrated cement forms a polysiloxane interpenetrating network structure. Through solid chemical bonding reaction, the micro-structure of concrete surface is endowed with long-term hydrophobicity, and the function of breathing and breathing is maintained. After silane waterproof treatment, the surface tension of the base material is much lower than that of water, and capillary counter-pressure phenomenon occurs, which does not block the capillary holes and keeps the "breath" of the concrete structure waterproof.
