TECMADRY® MILENIUM is a one-component cement based hydraulic waterproofing material, which is especially designed for penetrating the concrete micrangium net and through a series of chemical reactions which lead to the formation of non-soluble crystals, seal the above mentioned micrangium net blocking the passing of the water and acting for or against pressure. TECMADRY® MILENIUM does not alter the conditions of vapour exchange of the support, thus allowing its natural transpiration.
