Percolation Tests questions, answered by experts

Asbestos-containing materials are not easily affected by water and do not disintegrate or dissolve when exposed to it. However, porous materials can deteriorate due to water exposure, leading to the release of asbestos fibers into the air. The settling of asbestos fibers can also occur as water makes them heavy, which reduces the risk of airborne exposure, though future disturbance of the materials could cause risk. Wetting asbestos-containing materials does not constitute safe removal, and the proper handling and disposal of asbestos materials should be left to professionals.

Common areas include insulation, flooring, ceilings, and siding in older buildings. Professionals identify potential risks.

Asbestos testing takes place in two stages—collection and lab testing. Collection can take less than 20 minutes if a professional manages to get a direct sample. If air samples are required, then the pro will set up a testing device and return to collect it. In both cases, the sample is sent to a lab and results are confirmed or denied usually within one to two days.

Clear the area for access and inform the testing team about the building’s history and renovations.

Regulations require certified professionals for removals and disposal in compliance with local and federal guidelines, ensuring safety and legality.
