Hey all.
I have a tunnel that runs underground for about 100'. It is highly contaminated with things like Pu-239,
Am-241, Sr-90 etc. etc. I want to fill it with grout, but that presents a weight problem for shipping. I am interested in any info on other materials that would do the same thing without the weight. Has anyone used a light weight foam product for a large area that will eventually be segmented with a diamond wire? Any ideas are appreciated.
Thanks in advance,
Brett
Oh by the way, tunnel is about 3 1/2' squared.
