Temporary Platform

[NickRose2006]

Two weeks ago my family moved into my grandparents home which is now my moms house. Anyway we will be digging up the backyard to put in a new lawn next summer, so I can't put in a permanent pier yet. I decided to dig 3 holes and put in cinder blocks. It took several days to dig all three holes. Below maybe 4 inches of the top soil it became very hard to dig, so I filled the holes with gray water from my washer and let it soak over night. When I was reading how to conserve water I was reading how grey water from the washer can make hard dirt looser. By my surprise it was a lot easier to dig.

Here are some pictures:

My backyard is all clay. I'll try the gray water trick next time.

Looks like a solid platform. Did you fill the voids with sand?

Thank you. No, I actually just used the dirt/clay that came from the holes and then I poured some water in so the dirt would move into any voids.
