Cordar was born in 1978 from the action of 38 Biellese Municipalities to intervene on the increasingly pressing environmental problem, linked to water pollution and due, in particular, to the massive presence on the territory of textile companies.
The Biella purification system was designed precisely on the local industrial set-up, with the three large plants of Biella, Cossato and Massazza, in order to serve the territorial production complex in the most efficient way. For this reason, in fact, the 150,000 effective inhabitants of the area correspond to plants with a largely oversized capacity, equivalent to 680,000 users.
Purification involves a set of actions aimed at removing contaminants from urban or industrial wastewater, before being “returned” to the environment.
The Massazza purifier protected from chemical aggression and waterproofed with the PENETRON ® System
The Massazza purifier, in particular, has been protected from chemical aggression and waterproofed with the PENETRON ® System , which has allowed a drastic reduction in construction site times and cost optimization.

Penetron ® Admix is the most important element of the System: it is added as an additive to the “mix design” of the concrete in the packaging phase, to obtain a complete, capillary and active waterproofing of the structural matrix over time. This innovative technology, thanks to the exclusive formulation of reactive components, drastically reduces the permeability of the concrete and the cracks due to excessive thermal gradient or contrasted hygrometric shrinkage, increasing the performance characteristics of the matrix and the durability of the work precisely “from the beginning” . The behavior of the “self healing” additive of the concrete remains active in the vehicle moisture-water present in the underground structures and in the hydraulic works and guarantees the waterproof seal.
