on the floor of our punch porch, under the carpet, it's cast with a material I'm wondering what it is. It is black and hard. But it doesn't feel quite cold like concrete. pondering because I have to chip away a bit before we lay new flooring. Close-up of a punch porch floor with a black, hard material showing cracks and debris, alongside wooden floorboards.
 
Thinking so it's not some form of death asbestos mass that causes lung cancer directly..

Best regards

It feels reasonable, is it something you dare to dig into a bit without having a spacesuit?

Of course you dare to do it! It is an oil product, but it never hurts to use a mask when tearing down! I always use jungfrubröst when I rip in the house.
 
Anyone have any knowledge on how to sensibly demolish this?
It's rock hard and fused under the tongue and groove...
I really need to remove it, and I'm using a crowbar but am considering if it can be heated in some way, but the thickness makes me think it will be difficult...
 
S
definitely should not start heating it.
perhaps try with bilmaskin and breddmejsel
 
I have a small rotary hammer that I'll try out tomorrow.
 
Went with it, and amazingly enough, it was possible to break off large parts once enough had been removed to get the crowbar in, lucky that:)
