Abestos?
Location: Nebraska USA
House built in 1947. This is the basement of the house
We removed a 3 year old carpet + foam pad and found a layer of crumbling yellow pad + green layer on top of the concrete. The yellow pad was already like dust. The green/dark green layer come up when we scrape the yellow. The green layer detached the concrete like a layer of paint..... Might this green thing abestos?
We wore layers of mask when we scraped. Didnt know it may be abestos...
