Bryan,
I researched this stuff when I designed my last house. If I remember correctly it has a crush resistance of 25 lbs./sqin. It was used under the highway built over the tundra to support the Prudhoe Bay oil development to float the road and prevent the melting of the permafrost. I think I calculated that if I put it under the basement wall footings it would support the weight of the 10" concrete walls and the story and half house built on them. So it should handle your butt without any problem.
