## Questions & Answers

**Q: What is the measurement from the base of the block (ground level) to the base where the bottom of the joist sits?**
A: 2”

**Q: Can they be used for fence post?**
A: No, they are really not appropriate as a fence post base.  They aren't designed to supply much lateral support.  They're meant to support a deck post.

**Q: My local building inspection office requires an icc, intertech, or similar  evaluation product evaluation for new products  does this have one?**
A: Yes, their website shows the product has been evaluated and been certified. Search Tuff Block certification and the search should take you to the web page with the information!
Good Luck!

**Q: How many would i need for a 20'x20' woodworking shop/ shed with a loft?**
A: One big package does 10x10 so I would get 2. I had maybe 5 blocks left over.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy, fast and sturdy!
*by J***B on October 18, 2020*

Lifesaver! This product saved me thousands of dollars! The floor of my 1800’s barn kept washing out. We removed all the old wood and damaged beams. My carpenter was going to put new support beams in and replace the floor running 10-20k! I was convinced I could put a deck floor in there using cinder blocks. After researching this, I found Tuff Blocks. I ordered them and they were delivered quickly. I put some gravel from the driveway into the barn, tampered it down and laid the Tuff Blocks out. With some leveling we got the joists placed and screwed in the floor boards. It was a couple day job. Very easy and cost me about $900 in materials. The beauty is I can easily unscrew it and pull it up if we have another flooding issue. I couldn’t be happier with it and I owe it to these fabulous Tuff Blocks!

### ⭐⭐⭐⭐⭐ Freaking Awesome
*by A***R on April 21, 2022*

Built a 12x10 studio shed using these things and it is rock SOLID.Did not have to break the ground or cut into my turf to do it. Would absolutely recommend for a shed, deck or anything needing a floating foundation. Not real popular out here on the West coast yet, it seems as no one had these in-store, but as a 'bored during COVID' project, these things took a lot of work out of what could have been a nightmare. 5 stars all the way.

### ⭐⭐⭐⭐⭐ Great Blocks
*by A***A on May 18, 2022*

Easy to use. Sturdy. For a solid shed deck. Lightweight. Will use these blocks if I need to build anything again.
