Percolation Tests questions, answered by experts

If you can locate building records, you may be able simply to see what type of tiles (or bonding agent) was used. Any flooring made between 1950 and 1989 more than likely contains asbestos. Asbestos tiles can also be slightly thicker than other tiles and often measure 9” x 9”, 12” x 12”, and 18” x 18. Black mastic was a commonly used adhesive that contains asbestos.

Testing and analysis take 10 days to 2 weeks. Expedited services are available for urgent situations typically requiring higher fees.

Older textures may contain asbestos, requiring careful handling and professional inspection before work begins to ensure safety compliance.

Asbestos fibers can stay airborne for 48 to 72 hours, depending on the home's ventilation. Fibers can linger longer in enclosed spaces with poor airflow. Because the fibers are microscopic, they can easily remain suspended, making them difficult to detect without professional equipment.

Damaged tiles can release asbestos fibers into the air. Anyone in the surrounding area who may inhale the fibers will have them settled in the lining of internal organs. Over time, it may lead to serious health conditions such as lung cancer and mesothelioma.

The only safe way to prevent these conditions is to avoid exposure to asbestos at all costs, even for a short period of time.
