Shed Foundations: How We Build Them at Site Prep 

Thank you guys.

Hi Randy, this is the same ground-contact rated lumber that would be used in deck posts, etc. I believe they say it's usually good for at least 40 years.

Glad to hear you were pleased with our work! Thanks again for trusting us with your shed foundation!

Great! Glad it was helpful!

Hi William, it's usually best to remove the grass because the top level of soil is more likely to settle overtime. Also, if you add the perimeter of 4x6 lumber on top of the grass, your shed will be that much higher when the foundation is finished, which can be a problem if you are moving things with wheels in and out of the shed. By digging out the grass, you can get the door of your shed closer to ground level. Just some things to consider. Good luck with your project!

@@site-prep Hey buddy thank you for getting back to me and for the info. You're absolutely right about the foundation, I didn't think about that. Thank you and take care bud.

Yes, you should be able to do that. You want the foundation to be as close to grade as possible on whichever side the shed door will be located.

Hi there, It could be that the ground underneath is a bit damp or that the stone wasn't tamped particularly well. At this point, your best bet may be to let it dry out as much as possible and then tamp it again. If you're able to get some, you could also add a bit more crushed stone when tamping the soft areas. Good luck!

Thank you so much for your kind review Rachel.

Thank you.

We're looking forward to it too!

As of November 2021, we have crews based out of Gap, PA and Harrisonburg, VA. You can see our current service area here: www.siteprep.com/areas-served/

We recommend '3/4" clean' stone.

@@site-prep thank you so much!

Hi Eliyyah R, I'm not totally sure what type of plastic you have in mind. It needs to be a material that allows water to drain through so it doesn't sit inside the shed foundation. It should also be strong enough to withstand the weight and roughness of the gravel on top of it without deteriorating.

Hi, so I was asking particularly about 6 mil polyethylene. It’s what I had so I just went ahead and used it. Basically, since I was building my yard up, I didn’t need to dig down. I just put my treated 4x6 around it stacked two high laying flat. I used the 6 mil sheeting as my weed barrier and stapled it to the insides (like you guys), then poured my gravel on top of that. I didn’t do any drainage underneath or poke holes in it. I guess if I have to I can use the sides since my foundation is 1.5 ft wider than the shed all the way around. There’s room for me to dig down around the sides to poke holes in the sheeting “if I have to”. This is why I was asking. Thanks!

Sounds good! Hopefully it doesn't hold too much moisture in there :).

@@site-prep where does a guy buy this type of fabric at?

@@site-prep what’s the name of the commercial grade fabric you used? I missed it through your accent 🙂
