Water is our most important natural resource! In water supply systems and wastewater management structures concrete is the most commonly used construction material. Higher plant throughputs, more efficient handling and new processes for the treatment of fresh and waste water have given rise to more demanding durability specifications. Concrete is an alkaline material and therefore by nature not resistant to acid, and conventional protective coatings, based on reactive resins, have not always produced the desired results.
For more than 40 years MC-Bauchemie has been meeting the challenges of developing permanent systems for the protection of concrete and the restoration of damaged concrete surfaces. The decades of research led to the development of new mineral-based systems, which now, after 10 years in use, have proven performance on site and passed all practical tests with flying colours.
This brochure gives an overview of a number of international projects in the water and wastewater management sectors. Whether using a mineral-based or highly acid-resistant polymer-silicate surface protection system, durable results are assured with MC’s products.
MC offers you not only innovation and competence in research and development, but also advice and assistance on site. An extensive network of competent experts that are versed in the special application technologies ensures the success of your construction project.
Competence and experience: MC is your partner for preventive surface protection and restoration in the areas of water supply and wastewater management!

Cracks in the concrete walls of the digester tanks, if unsealed, would have permitted the leakage of sewage under treatment. Due to the pattern and location of the cracks, it was neccessary to use a combination of rigid and flexible resins. The selection of resin was based on whether the point of injection was to form a single rigid element or whether to allow for movement. Thanks to MC-Bauchemie’s wide range of products, the engineers could easily select the most appropriate material and consider all design factors.

The primary sedimentation tank of the watewater treatment plant in Friesenheim (southern Germany) was repaired with Nafufill KM 250 and coated with MC-RIM. Inside the screw pump the trough surfaces of the Archimedean screw were corroded, decreasing the delivery rate. This not only led to a rise in energy costs, but also caused hydraulic problems because of the increased backup in the collector. After it had been repaired with the mechanically resistant MC-RIM, the pump could once again be operated at full capacity.

After 20 years of operation, repair and protection measures for the concrete surfaces became necessary. Eight sedimentation tanks with especially heavy loading in the water exchange zone were lined with MC-RIM.

WILSELE NEAR LEUVEN, BELGIUM
Wastewater Treatment Plant Wilsele
46
Objective:
Elastic filling of cracks, surface protection
Product:
MC-Injekt 2300, MC-RIM
Year:
2003
Project Information:
The wastewater treatment plant Wilsele purifies a major portion of the wastewater of the Flemish city of Leuven. During the construction cracks formed in several of the structural elements. These were sealed permanently with an elastomer-resin-combination MC-Injekt 2300. A permanent surface protection was achieved by applying MC-RIM.

Elevated Tank Objective:
Repair and surface protection
Product:
MC-RIM, MC-RIM F, Nafufill KM 250
Year:
2003
Project Information:
Damage as a result of corrosion was found on the concrete walls and columns of the elevated water tank operated by the Saarbrücken public utilities board. The restoration plans called for systems that would guarantee a minimum service life of at least ten years. To determine this, extensive tests with various systems were performed on site. The assessment by an independent test institute resulted in top marks for the highly sulfateresistant mortar-systems MC-RIM and MC-RIM F.

Reservoir in the Voest Objective:
To stop water from leaking through cracks in the concrete
Product:
MC-Injekt 2300, MC-Injekt 2033
Year:
2000
Project Information:
Numerous cracks had enabled water to penetrate through the concrete lining fostering the growth of plants and roots which could have caused further deterioration. The cracks were partially sealed against pressurised water with MC-Injekt 2033 followed by permanent sealing, through injection packers, with MC-Injekt 2300. The combined use of MC-Bauchemie´s foam and polyurethane products ensured a successful job.

Sedimentation Tank Rauch Fruchtsäfte
50
Objective:
Wastewater resistant coating for sedimentation tank constructed under adverse weather conditions
Product:
MC-RIM
Year:
2002
Project Information:
Rauch Fruchsäfte GmbH of Austria has an annual production of approximately 160 million litres of fruit juices. It became necessary to add another sedimentation tank to the company´s wastewater treatment plant. The original concept was to line the new tank with a polymer system but this was changed to MC-RIM to enable application under adverse weather conditions which would not have been possible with the polymer system.

Surface Water Purification Plant Tegel, Module 1 Objective:
Repair and surface protection of concrete using sulphate resistant materials
Product:
Konusit KK 10, Konusit KK 30, Konusit HB, Konusit NB, Nafufill KM 250 HS
Year:
2004
Project Information:
The plant was built between 1980 and 1985 in order to improve and maintain the water quality of the popular local recreation area Tegel Lake. It eliminates phosphates from the tributaries Tegeler Fließ and Oberhavel. The employed flocculant caused heavy concrete damage on all three modules through sulphate attacks. MC provided materials to meet the high technical specification and thereby facilitate execution of the project
