pure, solvent-free product
low volatility
watervaporpermeable, colorless impregnation
not film-forming
seals hairline cracks up to 0.3 mm
significantly reduces absorption of water and damaging
water-borne salts (e.g. chlorides)
very good penetration
very high alkali resistance
frost resistant
stops alkali/silica reactions in concrete
For the waterproofing of mineral substrates, in particular
low-porosity substrates such as:
concrete (road bridges, port installations and all marine
