I am having a new heat pump installed in a couple of days. I want to put down 4" tall landscaping blocks first and then have the preformed pad put on top of the blocks. What would be a good material to put under the landscaping blocks to make sure they don't shift or sink. I bought a couple of bags of pea gravel, but after thinking about it, that might be other materials that would be a better choice.
The reason I need to put down the blocks is because the current area has sank down. At some point I am going to have to regrade the area for better drainage away from the house and with the blocks and pad, that should raise it up about 7 inches from where it is now.
Thanks for any suggestions.
