Based on its extensive experience in this field, Silways is regarded as a leading China manufacturer, supplier, exporter of silicone water repellents. The waterproofness of the product has been subjected to various rigorous tests to ensure its effectiveness.

Building materials that have been treated with a silicone water repellent retain their vapour permeability.

This is because organosilicon water repellents do not seal the pores at the surface of the mineral masonry substrate, but form a very thin layer on the pore walls. Siliconized pores are no longer wetted by water, and capillary water uptake is prevented.
