IsmailG Posted August 14, 2018 Report Share Posted August 14, 2018 Built a base for a shed I bought out of pressure treated 2x6 and plywood. Is it ok to leave it directly on the ground, or should I put some blocks under it? Link to comment Share on other sites More sharing options...
Fly By Nite Posted August 14, 2018 Report Share Posted August 14, 2018 Cement blocks over a layer of crushed stone. Link to comment Share on other sites More sharing options...
nightfighter Posted August 14, 2018 Report Share Posted August 14, 2018 Ideally you should have a 4-6" compacted base of stonedust and then concrete block. If you have the compacted base, you could go direct with the PT. But prepping the surface is step one, if you are going to have any significant weight or spend any time in there. Winter curse will push it out of level if on just soil. Link to comment Share on other sites More sharing options...
Fly By Nite Posted August 14, 2018 Report Share Posted August 14, 2018 If its wood you should install gutters and leaders and paint the exterior. Will extend the life of the shed by years. I would definitely not leave it on the ground...it will rot quickly in this climate.

IsmailG Posted August 14, 2018 Author Report Share Posted August 14, 2018 It's plastic. Just lawnmower and garden stuff going in there nothing too heavy. Good thing I have a bunch of left over gravel Link to comment Share on other sites More sharing options...
IsmailG Posted August 14, 2018 Author Report Share Posted August 14, 2018 Was hoping to avoid any more digging lol Link to comment Share on other sites More sharing options...
Fly By Nite Posted August 14, 2018 Report Share Posted August 14, 2018 if Its plastic i would go right over the grass unless you want to lay it over some decorative stone. Link to comment Share on other sites More sharing options...
fluke07 Posted August 17, 2018 Report Share Posted August 17, 2018 What size? bigger than 100 sq. ft., NJ Building Code requires foundation/footings. Link to comment Share on other sites More sharing options...
IsmailG Posted August 20, 2018 Author Report Share Posted August 20, 2018 10x8. I just lined the base with blocks and put the PT frame on top, spot on the yard is almost perfectly level. Putting together the shed was another story, what a pain in the ass. Most of the holes where the tabs connect into weren't cut out properly.

rwalter7 Posted August 20, 2018 Report Share Posted August 20, 2018 (edited) for my 8x12 wood shed, I did 2 layers of PT 4x6 with 1" gravel that the shed sits on, basically a big sand box with PT having direct contact with the ground. Nailed the 4x6's together with rebar that penetrated to the ground. I notched the corners like lincoln logs with the rebar going through the corners.  Did it about 10 years ago. The PT 4x6's have begun to rot especially the bottom ones in contact with the ground. I've had one corner split so secured it back with 12" spikes. So far so good but at some point the PT box will have to be replaced. Not sure how I'm going to go about this. At some point I'll have to jack the shed up and redo the base. Not looking forward to this job.  My suggestion, provide ample drainage. Edited August 20, 2018 by rwalter7 CT Link to comment Share on other sites More sharing options...

rwalter7 Posted August 21, 2018 Report Share Posted August 21, 2018 If I had to do it over again, I would have compacted the area and put down some pavers then put the 4x6's on them and maybe put some pavers in the sand box and the gravel on top of the pavers. Over the 10 or 12 years that has been some settling due to weight.

Cape Posted August 24, 2018 Report Share Posted August 24, 2018 Paint roofing tar on the part that contacts the ground. I did that on fence posts and it lasted for years. Link to comment Share on other sites More sharing options...
