When I installed interior drain tile, I used filter fabric to line the excavation before placing the granular fill (clean rock and sand mixed) because the surrounding soil was silt and clay and the fabric increases the area of filtered water entering the drain tile that socks can never do.
I had a guy with a gas saw (open the windows) score the slab halfway through and then I used a sledge to knock out the chunks when I had time. My 12 year old son and I carried out the chunks. When it came time to dump the file he and a couple of friends threw the sand on the rock (no scientific formula) and hauled buckets into the basement. I mixed the bags of pre-proportioned concrete mix and placed it when an area was ready.
Much easier and cheaper than digging around the house with sidewalks, attached garage and landscaping. It took 4 week-ends and a few nights during the week when I had time from start to finish.
Bombastic idiot - say hi to my friend and French traveling companion for several years through Europe, Didier (DDA) when you return, if you get there. - His wife is a 5' 8" blond from Texas and he describes himself as a little "French Dwarf".
