special building materials concrete protection

concrete protection I
(in severe chemical attack)
In digesters for biogas plants in digesters of sewage treatment plants and drainage systems, etc. are emerging over the years, serious damage caused by fermentation processes floors to the walls and concrete. to stabilize

To the strength of concrete from the inside or restore a particular concrete protection system was developed -. First, the damaged area may also be primed with a barrier layer of mortar covered. Then the deployment follows with a special mineral surface sealant to the pressure-water-resistant surface seal, worked with great care must be to avoid cracks and flaws. Thereafter, a thin surface coating on silicate / polymer base is sprayed on, which to penetrate deep to 2 cm in the concrete and reduces the pore formation. From the outside
the concrete facade with a cream or with a powdered mineral color, the water vapor permeable and protected algae, mold and fungus resistant acts. Alternatively, you could also use thick bitumen coating or a highly elastic Sealing material (rubber / bitumen) apply.

concrete protection II (in low chemical attack)
Similarly produced in compost, silage flat silos, stables, etc. in Kotflächen wear in the concrete. Here, too, steaming open products like concrete protection I used. The primer and sealing surface is adapted to the severity of the damage and is always open for new coat with other vapor coatings. In low damage in the concrete strength can even be reactivated again. Here, the same products as I used concrete protection.

concrete / oil protection
In machinery spaces, Hoftankstellen, garages, etc., the concrete with oil, fuel, lubricants, deicing salt, and more severely affected. These areas should also be more slippery. Here is a primer first with a thin, liquid concentrate Polymer-/Silikatbasis. It reduces the pore volume and the penetration of oils, fats and water in the concrete. Then you can continue working with mineral materials.
