Protective coatings for tank linings and corrosion protection

Sika offers a wide range of protective coatings for steel or concrete structures. Used in large thickeners, leach tanks, floatation cells or as corrosion protection for exposed steel structures, we cover the whole application range. The products are either manually applied or by the use of special spraying equipment.

Concrete for long service life

Tunnel linings have to be protected for long lasting service life. For permanent protection and for visual design of the tunnel construction, effective surface protection systems are used. They have a firm bonding with the substrate, are resistant against stress from de-icing salt, moisture and damages from air and act as a protection against carbonation. These coating systems do not restrict the diffusion of water vapor and slow ageing process of concrete. Sikagard range of paints covers all these applications and it is referenced.

Protection for concrete lining

All systems of Sika are tested and certified in accordance with the applicable rules and regulations. Basically distinction is made between surface protection systems for surfaces that cannot be tread on and driven (e.g. ceilings, tunnel walls) and systems, which are mechanically stressed (e.g. cycling and pedestrian paths). As simplest protection system, hydrophobic impregnations are used. The Sikagard® range offers as well coatings able to penetrate into the substrate, create water-repellent surfaces and protect the substrate from penetration of harmful substances.
