Construction—EMEA—France—Commercial Buildings Technique Béton supplies Special Products for Europe’s largest Wastewater Treatment Plant With an operating capacity of 2.1 million m³ of wastewater per day, the Achères treatment plant in northwestern Paris collects approximately 80% of the wastewater of Paris. This makes the plant the largest sewage processing plant in Europe and the second largest worldwide after Chicago. Within the scope of a modernization and enlargement project, the wastewater treatment plant is being upgraded to comply with the new European Water Framework Directive and to serve the growing population in western Paris. Construction work includes two new parallel facilities for the biological treatment of sludge. A total of 27,000m³ of concrete was needed for the new wastewater treatment plant. Technique Béton supplied a large range of products that ensure a high-quality execution on the jobsite. This included the synthetic mould release agent Décosyntec ® 2005. In addition, the following special products were used: ■ ■ Ravalchoc ® PMES, a mortar with a high sulfate resistance that is suitable for aggressive environments ■ ■ The mortar Ravalchoc ® Flexible Etanche used to create a waterproof bond between the concrete cone Laroche ® Concrete Cone and the wall. ■ ■ Finisol ® Self-Levelling Mortar for levelling the floors in the jobsite area ■ ■ The finishing coat mortar Finimur ® and the finishing coat paste Revet Cryl ® Thanks to the company’s know-how, different mortars with the right color have been delivered to the jobsite. Thus, the light grey repair mortar, Ravalchoc ® GC, has been used to respond to a special color request. Technique Béton is proud to have contributed to the modernization of the largest sewage works in France by supplying its high quality products.
