Fort Decking Foundation Deck Blocks, Designed to Accommodate 4x4 Posts, 2x4, 2x6, and 2x8 Joists and Beams, High Density Plastic, Black

I built a 12x16 green house on top of these. They are plenty strong. Would definitely use again.

These are way more user friendly than cement pier blocks. They worked great for my 16x8 shed build. Sorry, no pics of the shed in my gallery.

Massive supports

Decking system used for shed build, works great, easy enough. Beats a post hole digger. Honestly someone could not pay me to used a post hole digger for what these cost. Yes, one must provide a flat surface onto which to place the blocks, but this is easy digging. A ground cloth and some gravel and your ready. I did need to heat a couple blocks (it was a cold day) to fit the 4X4 post into pocket. Could have chamfered the end of post but I got to enjoy the heat as well. I am sure I could of driven the post into block but that would have required a trip back to barn for a bigger hammer. I have yet another shed to build, more blocks to buy!

Great quality, sturdy and solid feel

Excellent.

I went with these fortnite deck system because they were easy to use in the area I was working at. Had very large oak trees surrounding the shed I was building. And really didn’t want to attempt to dig out for concrete footings. These worked well I used 4 x 4 short post, attached to 4 x 4 skids to get it level and support the shed

Work really good but had a hard time getting the post to fit did some modifications to the post then it worked fine.
