Prep for Basement Slab

After we finished the rough in plumbing, had to get 4" pea gravel set, vapor barrier laid down, and rebar set.  I estimated that I needed about 30 yds of pea gravel (didn't use crusher run because pea is self compacting) but the quarry only sold by tons about the equivalent was roughly 32-35tons of gravel.  So, order up a full load that was 32.68 tons .... that was way short so ended up having to order another full load and had about 4-5 yds left over.  What I didn't think about was that the gravel was wet so I was paying for water weight but was way short on material (lesson learned).

John was bringing the gravel via backhoe and dumping inside the walls, then I would use the Dingo to move and spread around the basement area.  This took about 3 days to complete and one day a neighbor, Mike, who is also building down the street stopped by with his backhoe and helped out as well.


 After getting it spread 4" thick, we spread out the 6mil vapor barrier (aka plastic sheet) and overlapped the joints 12".  I had wanted to tape the seams (best practice) but it rained so wasn't able to.


 Finally after many hours of prep work, finished off the the area with all rebar tied in an 8'x8' grid.  Big thanks to John for helping out to get this done (Note - this will become a common theme :-)  Next stop, basement floors.
