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.
