Water Management Industry
Waterproofing clean water reservoirs and tanks
Water management industry is a major topic that covers a wide range of sub-topics related to the use and treatment of water including clean water, wastewater, dams, pipes, channels and aqueducts, power and even industrial plants.
Water, a resource to preserve
It is common knowledge that water is the source of all life and ensuring its retention and maintaining the quality of drinking water and has been a priority since the beginning of humanity. Today the most used materials for water tanks are reinforced concrete or prestressed concrete. However, since the contamination of water can be easily caused by bacteria, viruses, algae, gas intrusion and so on it is of vital importance to utilize proper waterproofing technologies and pay particular attention to quality control to mitigate negative effects especially for drinking water.
Legal water treatment requirements
In addition, there are also strict legal requirements in relation to the storage of drinking water, that we must take into account when choosing waterproofing solutions for potable water facilities. This means that mandatory tests and approvals must be insisted on before applying waterproofing solutions.
Wastewater treatment
The treatment of wastewater also faces some unique challenges. It might surprise you to learn that our environmental awareness takes its toll on wastewater treatment facilities because reduced water consumption leads to a higher concentration of contaminants, which, in turn, accelerates the corrosion of concrete. Apart from traditional coal tar epoxy coatings which are cost-effective and relatively easy to apply, other technologies and products are also emerging to help overcome these new challenges.
Our experts have also managed to develop an innovative, reliable and highly efficient concrete waterproofing and protection system – MasterSeal 7000 CR – which provides a better waterproofing experience. Combining resistance to chemical and mechanical impact with effective crack-bridging properties in wastewater systems, MasterSeal 7000 CR reduces the risk of unexpected interruption-of-service and significantly extends maintenance cycles. Its long-term protective effect has also been tested by the Fraunhofer Institute for Environmental Safety, and Energy Technology under conditions that simulate a sewer system over a 11 to 14 year period. The Institut found there were no significant changes to the properties of MasterSeal 7000 CR. We can proudly say that MasterSeal 7000 CR has not only been used in European cities such as Poznan, Poland, but also in Asia including the water management facilities at Shanghai Chemical Industry Park, China’s first industrial area specializing in petrochemicals and fine chemistry.
Dams, Channels, Hydropower plants and other water related structures
Apart from drinking water and wastewater management, the waterproofing of dams, channels, rails, roads and other marine structures is equally important. Used for flood control, water supply, irrigation, navigation and hydropower generation, dams can bring significant benefits to our society. In fact, hydroelectric power accounts for more than 40% of renewable energy generated in Europe! However, the problem is that most European dams were built in the 1960s and the 1970s and have an average life expectancy of 50 years or more. To avoid a decline in their effectiveness and potential threats to the environment as well as human safety, many will need to be refurbished soon.
A success story related to dam refurbishment is the waterproofing of a hydroelectric power plant in Madeira, Portugal. To ensure the uninterrupted operation of the hydropower plant, the hydroelectric reservoir of 70,450 cubic meters had to be protected against leakage and corrosion. The solution provided by us, not only met the requirements for a durable waterproofing solution, but also supported the utility’s commitment to sustainability.
