Pyrite Removal Montreal

Our building foundation experts will offer their extensive knowledge and experience to help guide you through the pyrite decontamination process.

Inspection and Quotation: We will first inspect the property; once the property has been thoroughly inspected by our specialist and then we will provide you with a comprehensive quote outlining the expenses, the scope of work, and every stage involved in replacing the contaminated backfill.

Pyrite extraction: All the contaminated backfill beneath the concrete slab, all the way down to the foundation footing, needs to be replaced to permanently eradicate pyrite. The main tasks of the work include clearing the whole area, breaking up and removing the existing concrete slab, removing all the contaminated backfill, and replacing it with brand-new, non-swelling DB certified stone. 

The foundation walls, concrete slabs, and floors beneath your home are more than supports for the space directly above them. They ensure the structure remains stable, transferring load from the superstructure to the earth. 

Les Fondations Nouvelle Génération Inc. will use advanced industrial tools to complete the excavation, pyrite removal, and replacement process. We guarantee that your home’s foundations are pyrite-free and sturdy. View our projects to learn more.
