Garage addition concrete questions
I'm doing a uni-pour on an 11' X 21' garage addition and have some questions on the prep work.
1. On the floor area inside the footings do I need to remove the sod prior to adding the crushed stone base? Can I just weed eat the grass down to bare dirt or do the roots need to come out?
2. It requires 4" minimum of crushed stone base but with the slope of the yard can I put in up to 12" of crushed stone (compacked) with out any problems? It would save on concete.
3. I will need a form wall to hold back the crushed stone from falling into the footings and I plan on using 2 X material. Is it recommended to remove this form prior to pouring concrete or can i just leave it and pour the concrete with the boards still there (encasing the boards in the concete floor)?
Thanks in advance.
