Is Drainage Rock a Good Choice for My Shed Foundation?
Asked by User12345!
I'm planning to build a shed that measures 8ft by 7ft, and I'm considering a foundation size of 9ft by 8ft. Is that size alright, or should I go bigger? I want to fill the foundation pad with drainage rock (like the one linked below), but I'm unsure if that's a good option. Also, for an 8 * 7 shed, do I need to use rebar for the foundation, or can I skip it? I'm located in New York, if that makes a difference. Thanks for any advice!

You're on the right track with that drainage rock. It's a solid choice, but renting a compactor to compact the gravel will give you a firm base. As for the rebar, if you're just doing a gravel pad and not a concrete foundation, you likely don’t need it, but it could provide extra stability if you decide to use concrete in the future.

Your foundation plan sounds good! As for using drainage rock, it's fine but can get pricey if you're buying it by the bag; consider sourcing it in bulk from a local rock yard if you can. They can also help with any specific questions based on your area. Just a tip: you'll need about 1 cubic yard for your shed size, which is more economical if delivered in bulk rather than bagged.
DIYExpert22: Bulk is definitely the way to go if you're looking to save some cash! While bags are easier to handle, it can be a hassle shoveling that much rock by hand.

Consider building a raised platform instead! I built a 10x10 shed by leveling out spots with gravel and placing cinderblock pavers underneath. I also added some 4x4s on top with the shed floor resting on that. It's quick, requires less digging, and looks pretty solid!
NewShedBuilder: That sounds way simpler! I'll look into that method for sure.
