Dry Ice Blasting For Mould Removal

Dry ice blasting is the most effective mould removal solution, reducing remediation time by as much as 80% per project. When blasted with CO2, the mould is immediately removed upon contact, causing it to shrink and detach itself from the surface. In addition, dry ice blasting draws out moisture from wood surfaces to prevent future mould growth. With high-pressure blasting at -78ºC freezing temperatures, restoration is successful for residential, commercial, industrial and institutional buildings.

Our Mould Remediation Process

Mould is typically identified visually or by smell. Its presence is then confirmed through quantitative testing.

An industrial hygienist will conduct surface tests and capture air samples inside the building, and then compare these samples to the concentration of spores outside.

Lab testing can also identify the types of spores and how many are present.

As professional remediators, Wickens follows a thorough procedure to ensure the mould is safely and effectively removed:

  1. The first step is containment. We use physical barriers as well as negative air pressure to ensure that nothing can escape the contaminated area.
  2. Soft contaminated materials are removed from the area, including insulation, carpet, and dry wall.
  3. Dry ice blasting is used to remove mould spores from all affected surfaces.
  4. HEPA vacuums filter microscopic mould spores out of the air during the remediation process.
  5. We apply an anti-microbial solution to affected surfaces to deter the mould from returning in the future.
  6. HEPA vacuums are used again to catch any remaining mould spores in the air.
  7. The industrial hygienist will return to conduct a post-test to confirm that the mould has been removed. If all is clear, then we encapsulate the area.
  8. Finally, we remove all containment and take debris to the landfill for disposal.

The Hazards of Mould

Mould and bacteria can cause a great amount of health issues when found in everyday living and working spaces. Common causes and habitats for mould growth include floods, leaks, plumbing problems, elevated humidity and inefficient cleaning. Allergies are on the rise, fungal infections have become common, and contamination has become a risk in production facilities, restaurant kitchens, and product and food storage facilities. Mould requires proper, direct treatment in order to remove existing spores and inhibit future growth by removing any matter that can support growth.
