Percolation Tests questions, answered by experts

If you own a stereo microscope, you should be able to see the fibers. The stereo microscope often can perform magnification up to 50x. But unless you have experience viewing asbestos fibers, you may not know exactly what you are seeing. Some fibers are curly, while others are long and straight. Blue, brown, white, and gray colored fibers are all possible.

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

Costs depend on the number of samples, property size, and lab processing fees.

Testing is crucial to identify harmful asbestos fibers common in building materials from older properties, ensuring safe environments and health.

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.
