Sample Collection & Analysis


Excerpt from the Government of Alberta, Alberta Asbestos Abatement Manual, August 2019, Chapter 7.1.1:

As part of a hazardous materials assessment, sampling of materials suspected to contain asbestos are collected. Verification whether a material contains asbestos cannot be done conclusively by visual inspection alone; samples must be analyzed for asbestos content. Samples must be collected by a competent person and packaged/handled carefully to prevent asbestos contamination or exposure. Bulk sampling is considered a low-risk activity and the appropriate procedures need to be followed.

Some examples of the locations and types of products that contain asbestos include:

Building exteriors

  • asbestos cement siding panels – flat, corrugated, shingles or accent panels
  • asbestos cement soffits – flat or perforated panels
  • asbestos cement roof panels – corrugated
  • roofing felts and mastics
  • building overhangs – thermal spray
  • stucco
  • brick and block mortar
  • loose fill insulation in exterior wall cavities (vermiculite)


  • vinyl asbestos tiles (VAT)
  • sheet vinyl flooring (asbestos paper backing)
  • floor leveling compound


  • t-bar ceiling tile
  • asbestos cement ceiling tile
  • acoustic and stippled finishes
  • plaster or drywall jointing materials


  • plaster or drywall jointing materials
  • stippled finishes
  • thermal spray
  • asbestos cement panels

  • vermiculite insulation (may contain tremolite asbestos as a contaminant) – known by the brand name “Zonolite”

Please note:

FLEET Remediation Services Inc. does not recommend that a homeowner cut into their building materials to collect their own samples, as they could inadvertently disturb the materials, releasing asbestos fibers into your home.

FLEET Remediation Services Inc. personnel are available for consultation, and can advise our clients on the best course of action for testing and managing of asbestos-containing building materials.
