Thanks for the reply, InspectorD...I appreciate it. I think that my timing on my post (right before a holiday weekend) is probably why I haven't seen many other replies...no big deal.
Well, I just got done a little while ago this morning rebuilding the block wall. Of course, here in the northeast, we've had all that rain and clouds, and today is bright and sunny, so I had to work fast with the mortar...thanks Mother Nature! I had maybe six 5-gallon buckets' worth of sand fill spill out when I removed the "back" wall of the old block...not as bad as I thought. Built up 3 rows of block; gonna have to jerk around with cutting blocks for the 4th row, as I can't remove the old layer completely-it has lots of aggregate and cement in the voids from the top slab. Oh well...
Thanks for the info re: demolition. Even $2000-3000 is a tough nut to swallow...

I found a calculator online, and determined that the slab alone weighs roughly 3+ tons, and with my 1/2 ton pickup, that's quite a few trips to the township dump with the junk, nevermind the beating this 45 yr old body will take sledging it apart! Guess I'm just gonna have to bite the bullet in a few years, since I won't be any younger...
Thanks again for your advice!!!!
