Liquid manure containers was carried out a concrete cleaning with Controll®Deepclean and concrete treatment with Controll®Topseal for the purpose of conversion as a fermentation rest Depot (part of a bio-gas plant). The treated area of the inner wall of the place concrete walls amounted to approximately 666 m2.

The place concrete wall must be protected of  the chemical attack by biogenous sulphuric acid and must be impregnated against improper leaks and surface sealing to avoid (valuable) gas outlets. The reinforcing steel must also be protected against corrosion. The concrete protection of the concrete had to however be exempted from organic substances (manure) which had penetrated into the capillary system over the years.

Were the 4-year-old place concrete walls with high-pressure water cleaned and then treated with Crontroll®Deepclean. After 3 hours of contact time, the concrete was again cleaned with high-pressure water and cleaned of the pollutants that are pressed out by the treatment with Crontroll®Deepclean. The consumption of Controll®Deepclean amounted to approximately 0.2 l / m2

And then treated a total of 7 times in the interval from 30-45 minutes with Controll®Innerseal on the inside of the place concrete circular tank ( with a low pressure spraying system). The consumption amounted to an average of 0.78 l / m2. The concrete had a glossy surface after treatment with Controll®Innerseal.

Special attention was given to maintaining the should and order speed. The  impregnation time required for the applications with Controll®Innerseal was 3 x 30 minutes at the 1st day and  4 x 60 minutes at the 2nd day ( including waiting times).

Treatment with Controll®Innerseal is solvent and aroma free, which excludes any permanently damage to the  important bacteria culture system. The thermal conductivity (DIN EN 12667) of the concrete wall is reduced in addition this procedure by 24 % (See certificate MPA Dortmund), what an average temperature difference of approximately > 6,2 ° C up to 10 ° C, dry, is equivalent. (Advantage for the operator: lower primary energy costs for the basic need for heat; lower exterior insulation necessary).

The place concrete circular tank was equipped with a 10-year-old product and functions warranty of Controll®Innerseal on the part of the manufacturer's, that represents a high additional safety, in addition to the VOB/BGB of the trades for the user.
