Elimination of Pyrite

Pyrite is found mostly in the 1970 constructions.  The problem is located predominantly in the Montérégie and Montreal Island area.

Pyrite is a sulfite mineral found in sedimentary rock used for crushed stones intended for filling. Complications arise in the presence of humidity and oxygen. The moisture under the concrete seeks to filter upward, which causes a chemical reaction.  With this reaction comes swelling and erosion of the concrete.
