removed, including digging out surface roots
to a depth of 2 - 2.5 feet, and out to 15
feet from the stumps. Most of this area has
been dug up and filled. The material is
Adobe, this is in Hollywood, California.
Now I want to replace the concrete slab that
the trees destroyed. Given that the adobe
has been disturbed to a depth of two feet,
what kind of compaction and other preparation
do I need to do? Should I rent one of those
aptly-named Whacker machines? If so, do I
need to dig out the loose stuff, whack the
area, and lay down layers and whack them?
Or is it good enough to just run it over the
top of two feet of loose adobe? Eventually,
when I get enough money, I want to put a
large hot tub on top of this slab. Before
that, I want to tile over it. So, I want
to make this plenty strong so it won't crack.
