I'm setting up a 10 foot diameter children's swimming pool. My land
slopes and I have to build up the soil by about 8 inches on one side
to make the area level.

What type of soil would you use to level the area? I've looked into
screened topsoil, but that seems to fine and might easily just wash
away when wet. All the companies I contacted so far just carry the
screen top soil. I don't want to use basic fill, but rather a
compromise between the two. Any suggestions?

Thanks.
