Great footer

Would Recommend

I used these as footers for a deck. I like it so much better than trying to make concrete footers. I was worried that my deck might slide down the hill, but it hasn't budged. If I ever change my mind and don't want the deck anymore, I don't have to dig up concrete footers. So, when it came time to create a raised garden, I decided to use these as footers, instead of sticking posts in a hole in the ground. I expect it will last longer if I don't bury my 4x4 posts. I considered laying the 2 ...

Awesome product and very versatile

Would Recommend

Bought 16 of these for a wood floor in my metal garage/workshop. I didn't want the floor to be too high above the gravel floor, as i left approx half of the space gravel for XUV and mower parking. These worked great, and i used 2x4's for joists and headers and 3/4 plywood sheathing for the floor itself. Very easy to position and level these bases, also very sturdy. Have already recommended them to a neighbor for use in leveling a pre-existing shed and will buy again if needed.

light and easy to use

Would Recommend

This product made my project a lot easier! I built a 10x14 deck using 2x6 and 4x4. I really liked the fact that the product was very light, as opposed to the concrete feet I have used in the past. Obviously, this was a small deck and very low to the ground, but after I was done, the deck was solid!

Affordable, Tuff, and EZ 2 Use!

Would Recommend

I tested four of these before building my floating deck. In short, 80 TuffBlocks later, and supporting a multi-level 12'x38' deck made from Trex, these babies are rock SOLID! So is my deck. Very simple to use; simple to position and reposition; and rated to half a ton per block. My deck ain't going anywhere. And, as it is a floating deck (not physically connected to the house), I did not need a permit or inspections.

Good flexible product at a relatively lower cost.

Would Recommend

I chose these because of the low cost but soon realized that cutting out a few small pieces of plastic also allowed me to accommodate 4x6 posts. I was also able to use deck screws to securely attach them to the posts. This is useful because due to the strong winds in Oklahoma, I buried the bottom 18-24” of the posts with these platforms attached. It would be difficult to attach the other options (concrete platforms) to posts and it would require digging deeper holes to bury them.
