The basement is fully finished and has a large recreation room with an above-grade window, a fourth bedroom with a double closet and a three-piece bathroom.
Finally, the entire exterior length of the first and fifth floor and the above-grade portion of the first basement will be sheathed in more protective geotextile.
The difference with rubblization is that above-grade structures, including the concrete containment building, are demolished into rubble and buried in the structure's foundation below ground.
