Pyrite Remediation

What causes pyrite problems?

Building materials used for the basement, such as aggregates, concrete, or mortar, may contain pyrite. If these materials contain aggregates extracted from quarries containing pyrite, this can lead to the introduction of this mineral into the basement structure. When wet, pyrite breaks down basement slabs or foundations.

Turnkey Solution - Execution 

  • Excavation: Carefully excavate the area affected by pyrite, removing contaminated soil and transporting it off-site for proper treatment or disposal in compliance with environmental regulations.

  • Material replacement: Once the pyrite-contaminated soil is removed, replace it with certified DB crushed stone (uncontaminated) to rebuild the affected foundations or structures.
