how many blocks will I need for a 90 square foot floor

Asked by ray April 30, 2021

Answer

That depends on the length of each side and the size of your joists e.g. 2x6, 2x8, 2x10, 2x12. Suppose it is 9' x 10'. You'll need 4 for the corners and assuming one for each center that's another 4 for a total of 8.

Probably 15-20 lbs each. 60 lbs must be an error.

What is the suggested weight or averages on these blocks can handle.

Need corner posts in concrete, no but you can. If your worried about high winds anchor the deck which like posts in concrete defeats the ability for these to move with the dirt under them. https://www.homedepot.com/p/ShelterLogic-30-in-Earth-Anchor-Set-4-Piece-w-Heavy-Duty-Corrosion-Resistant-Steel-Construction-and-Spinnable-Corkscrew-Design-10075/202719050?MERCH=REC-_-searchViewed-_-NA-_-202719050-_-N

No, they're meant for 4x4 to rest on it for e.g. a deck.

Would not recommend for use. Not designed for stacking. If you need heighth, a 4x4 post will sit securely in the middle of the cross section.

Post hole/slots much shallower than desirable
The slots prove level and nice tight fit for cedar, not so for treated pine. I have older blocks that have much deeper slots and provide notably more stability to slats and post. The older blocks are also more dense then current rendition. Ultimately the current blocks work and are stable base when corner braces were added.

What i received is not what was pictured
I ordered 4 blocks online and had them delivered to my house. The blocks that arrived have maybe 1 inch of space to hold a 4x4. Pretty much unusable and now I have to drive to Home Depot (which is what I was trying to avoid in the first place) and return them.

This product is great. I built a floating deck with very little digging (just to level) using these blocks. I didn't have to lay cement and it turned out just as sturdy using these patio pier blocks
