Even with proper operation and regular maintenance of a biogas plant, the aggressive and
chemical processes to attack and damage the concrete wall or the coating of the container. Even after only a few years of operation of a biogas plant, it can cause significant and visible damage to concrete and steel
because the biomass (the substrate) but also the biogas are highly corrosive. A refurbishment of the facilities is therefore not a matter of aesthetics, but rather a matter of safety in terms of
Environmental considerations and an investment in long-term economic viability and functionality.
Nesemeier GmbH offers professional renovation of defective concrete surfaces and components, as well as high-quality coating in fermenters, secondary fermenters and fermentation residue stores. We carry out all the necessary work steps for you, from substrate cleaning and substrate preparation to concrete restoration and the finished new coating. A rehabilitation by Nesemeier GmbH is carried out in a structured, fast and economically effective manner, because such a measure is a drastic intervention in the operation of your biogas plant.
Container walls are cleaned by us with a water jet high-pressure cleaner with up to 2,500 bar.
We process large areas highly efficiently with a washing robot.
This enables us to prepare the container in the best possible way for refurbishment and to create a
optimal substrate.
Sometimes not only the coating but also the concrete of the tank wall is attacked. The removal can amount to several centimeters, in severe cases even the probation is exposed to aggressive gas and substrate. In these cases we repair the tank walls with fibre-reinforced, highly sulphate-resistant concrete additives.
To make your container walls sustainable and safe for the operational stresses of the coming years We apply special coating systems. Our products are specially designed for the protection against biogenics Sulphuric acid or silage leakage juices developed and with the current building supervisory approval the system any requirement of the AwSV. Our employees are supported by our manufacturers in the Processing trained.
