In the first instance, the purchaser order a concrete with an exposure class XA2 for the construction of a container. The exposure class to be increased after the completion of the plant on the basis of the medium to XA3. The container is filled with a 35 ° C  up to 40 ° C warm industrial wastewater with a 6000 mg / l sulfate content. The pH value of the effluent is less than 3.5; may vary but very strong.

According to a report by the GERMAN CONCRETE AND CONSTRUCTION  TECHNOLOGY ASSOCIATION the exposure class XA3 is not sufficient in this case.
Exposure class XA3 according to DIN 1045-2 or DIN EN 206-1 applies to "chemically strong attacking environment according to table 2". Conclusion: It cannot be ruled out that  the used concrete with exposure class XA3 without further carried out concrete measures, such as coating, offer stratum or run as a concrete with high resistance against acid attack has no sufficient resistance to the described above attacking medium. Therefore, damage to the construction may occur as far as take a closer look at concrete chemical or engineering.

As protective measures, the concrete surfaces were treated with sump pump the two secondary sedimentation tank with Controll®Innerseal to achieve the required chemical resistance. The concrete was about 10 months after his processing, 7 times with Controll®Innerseal by simply applying with low pressure sprayer, treated. It was created as a permanent, waterproof protection for the steel reinforcement and concrete-aggressive media. The consumption of Controll®Innerseal total amounted to approximately 0.49 l / m2. The treated interface showed a slightly shiny surface after drying. The treated surface of concrete surfaces (C35/45 XC4; XD2; XF2; XA2) amounted to approximately 2,214 m2.

Controll®Innerseal is non-toxic and therefore not distinguishing mark according to the hazardous substances regulation. It is colourless, odourless, solvent-free, and non-flammable. Controll®Innerseal makes concretes resistant to chemical attack and impervious to water against both, positive and negative hydrostatic pressure, and is an active a deeply urgent corrosion protection of reinforcement steel in concrete (Deep penetration > 195 mm).  Also, any harmful salts in the mineral building material cast out during the crystallization and curing process.

Beyond the product properties Controll®Innerseal and Controll®Topseal stand out due to low cost and short lay on times.

We give a product warranty on the effect of Controll®Innerseal and Controll®Topseal by 10 years.



















Komsol Innerseal products have been approved worldwide for their ability to extend the lifetime of concrete up to 3 times.
