  Ted,

  My thought would be to build a foundation as would need for a road, =
etc. I suggest 6" of =BE" crushed rock. You need to pack this rock down =
well. Do you have one of those tampers that have a 6"x6" square plate =
and have a long handle. Then put down 4 to 6" of concrete with a mix =
suggested by Chris which I believe is one part cement and 1 part sand. A =
very rich mix. And I would suggest concrete sand rather than mason's =
sand. You probably should have some rebar in there too. Chris will some =
ideas too. Well, this is a start. You probably want to wait at least 6 =
months before you try a seismometer on the pad. I'm sure it will be =
talking.

  Hi All,   I am building a new house.   This house has no basement, but =
has a 24"? crawlspace under the house.   I have lots of time, to create =
a space for my three sensors, under the house.   I could also place them =
in the garage on the concrete floor.   My thought was to enter the =
crawlspace, and dig a small pit large enough to allow for elbow room, =
then line the pit with concrete blocks to keep dirt away.  Perhaps =
covering the floor area similarly.  Concrete may not be the best =
material.   I could also pour a pad or small footing using cement.

  Please any thoughts on preparing this space?

  Thanks, Ted
