Pyrite Inspection & Testing for Residential and Commercial Properties in Montreal, North Shore and South Shore
What is Pyrite and Why is It a Concern?
Pyrite, also known as "fool's gold," is a mineral found in the backfill material under concrete slabs. When exposed to moisture and oxygen, pyrite can oxidize and swell, causing significant damage to building foundations. This is a common issue in regions like Montreal, North Shore and the South Shore, where specific geological conditions increase the risk of pyrite-related damage.
what is a pyrite test?
This involves taking a sample of the backfill (crushed stone) located under the concrete slab (floor) to determine if there is a potential for swelling that could damage the building. We also check if the concrete slab is affected by sulfation and, where possible, if the natural ground has a potential for swelling linked to pyrite. Our services are available throughout Greater Montreal, including North Shore and the South Shore.

How Pyrite Can Affect Your Building’s Structure

Common Areas Where Pyrite Is Found
Pyrite is commonly found in the backfill material beneath concrete slabs, particularly in regions with specific geological conditions like Greater Montreal. It can affect both residential and commercial properties in Montreal, North Shore and the South Shore.
Affected Geographic Areas in Montreal, North Shore and South Shore
Pyrite issues are not limited to older buildings. Even properties built after 1999 can be affected, as the National Building Code does not require builders to use DB-certified backfill. This is a concern for homeowners and businesses in Montreal, Laval, South Shore, North Shore and throughout Greater Montreal.
