Hydrostop is a colourless product based on silicone resins.
Hydrostop can be applied on brick, cement, concrete, etc.
Hydrostop makes stony material water repellent so that water or rain can no longer penetrate into the stone.
Nevertheless, the wall preserves its breathing properties so that the transport of water vapour is still possible. Because of the fact that the wall remains dry, the pollution is minimalised; the colour and the aspect of the stone are therefore longer preserved. There is no longer frost damage and the thermical sealing ameliorates because a dry wall seals better than a damp one.
