These tuff-blocks are so much easier (and lighter) to use than the traditional post-in-concrete or the post-in-concrete block! My sister and I just finished my backyard deck using them which made that part of the building process that much easier. If your lot is unlevel (like was mine), just level the tuff-block on the ground, add a 4x4 post, level and attach the joist board, and you're done. We made the exterior frame first, then installed the interior tuff-blocks. Price can be an issue comparing to the concrete block, but your back will appreciate it! Not to mention, the convenience. If two women can do it, you can too!

I built a porch/deck/floating patio, whatever it's called. The TuffBlock design has me addicted to dreaming up all the other things I can build that normally I wouldn't have even considered. Why? Ummm, augers, concrete, plum, exhaustion! Yes, there's work involved with Tuff Blocks, but it doesn't have that same stress. It makes framing a pleasant process. If I could do it all over again, I would have bought a dado blade. Being a newbie, I didn't know that thing existed. Would have made getting the cuts for the 4x4 beams so much more precise. Dig past the organic matter, buy some rip rap aka paver base ... get that at a landscaping supply store - SO MUCH CHEAPER than bring home bags of that stuff ... smooth it, tamp it, level it, use a couple of over hanging "jigs" on your joists, measure, cut, install, BOOM - Porch!

great

Quick delivery...I'm still in process of leveling site, but the product appears more than adequate for my needs. I have previously used concrete deck blocks and these are easier to position and level
Christopher P.
Very easy to use. Great for a first timer
Jerry T.
Excellent product! They save us so much time compared to concrete blocks when we build storage sheds. They look much nicer as well
David M.
Cottage deck build out was easy with these deck bases
Mohusker
Great alternative to concrete block! Just finished a 30 x 40 ground-level deck around an above-ground pool. We place 1-3 inches of tamped paver base at each location requiring one-half to one bag of gravel each. Most of the joists attached to the wood retaining wall surrounding the pool and the best practice seemed to be establishing the height of the joist based on the retaining wall and height of the pool (we wanted to be just below the pool rim), then placing the first base and leveling each subsequent base therefrom. After trying the joist, a bit of adjusting was required. We built the rim joist first and leveled from the retaining wall to the rim joist. At the far end, we had to add a 2 x 6 post a few inches high. Unknown if any of the bases will settle, however it's a pool deck at ground level. We spaced the blocks four feet or less apart. Span tables say a 2 x 6 can span up to 7 feet seven inches. Note that the spacing on the blocks is different in each direction...number 1 is for 1 1/2 inch lumber. We easily trimmed the block verticals to fit cross-pieces between closely-spaced joist "ladders". Good choice; very easy to handle; sturdy; long-term results unknown.

Just as sturdy as cement blocks! These made building a deck a breeze! Everything squared up perfectly. Very sturdy.
Barry M.
Will use again. Great product. Easy to use,way better than the cement ones.
Hemied
Works great. TuffBlocks are easy to work with. 4x4’s fit in very snug
Michael
This Tuff block is really lower to the ground. Product was strong and has different sizes for 4 x 4 and 2 x 6 to 12
JLKSF
Wish I would have known earlier. Very easy to work with. Could have used these for previous projects.
Cheryl
These things are so awsome that we bought more to add onto our deck. Love'em!
Deni
A friend told me about these blocks. It sure was a lot easier to do my floating deck. The picture is before I put the joist hangers on.
Josh K.
These are a much better option than concrete blocks, designed for low-profile floating decks but these can also be used for taller decks (most codes limit floating decks to 30-36"). I opted to dig out topsoil and replace with tamped-down paver base. Rock solid.
candlemaker
High quality product works as represented.
Lewis G.
easy to work with, tough (as advertised) - perfect for the remote tractor shed I am building...
Mark B.
Used 18 blocks for this ground level deck. Nade vo struction so much easier.
The building inspector loved them
Pierre S.
It made the process go much quicker and feels VERY stable. I hope that they will produce some that can accommodate some short 6x6’s for a little bit heavier duty supports.
Craig C.
This is a follow up as BuildTuff invited a review. I think the result speak for themselves. See my other review for a framing photo. BuildTuff made a great and super strong Yurt platform.
Scott S.
Used Tuffblock as the foundation for two walkways. Simple to use and much less labor intensive. Used compressed limestone dust under the blocks. Curious to see how system works through a season or two. Nice and level to start.
Lautaro S.
great quality. love it!
Craig C.
I am building a platform for a yurt on an old mining tailings pile. The BuildTuff block has been a joy to work with especially since my joists are true cut 2”x8”. The layout was easy. We are really looking forward to this winter.
Brent W.
Deck turned out amazing. Thanks for saving me time and work.
Darvin M.
This is an incredible product and the owner is jsut as good.

These Tuff blocks were the "hit" for my deck repair!!! What could have been a 2 day job, turned to be completed in only 4 hours! They are so light and easy to work with and so incredibly effective! Best building find, and best product..EVER!!! My crew was amazed!!!
John H.
These are fantastic!!! Not only are they light - they are super strong! I built this floating deck and it turned out great (not totally done - but close) they also save lots of time by not having to dig! I love them
Nate R.
Just looking so far
Do t know what I clicked on to get this box
Thomas H.
They are fantastic
Stephanie C.
We had a deck built as part of our barn remodel and our general contractors LOVED working with this product! They said it cut down the time they needed by at least 1/3.
Joseph G.
These block were the best. Easy to place, light and everything fell into place just as planned with this 24X30 foot deck.
Steve b.
Easy to use and works great
Randolph P.
I am building a 10’x10’ deck. I live in the Texas hill country on a hill which is primarily stone. It is a steep hill as well. Without the TuffBlocks, it would have been very time consuming and costly to dig holes for footing. I am very happy with the product and would definitely recommend it to anyone considering building a deck.

Mark M.
These work great and I’m going to be using more on a different project.
Kenny M.
These things are awesome. Makes the job so easy and fast.
Verna J.
Love these tough blocks they are light weight and easy to use. I am glad I found them.
Dave M.
I won’t be taking it out of the box for another 6 months or so let’s try again then.
Jessie B.
great product. arrived on time. did the trick! thank you
Denise S.
We both have severe back issues..we found tuff blocks and thought it was a great option for people who can’t lift much..IT was!! So easy to use, very stable, perfect fit every time! It was our first time building a deck.. this product made it so easy and less hectic on our bodies. My husband was injured in Iraq and I, a car accident… I recommend this product to Everyone!
bob s.
We used them were we needed to be temporary worked great
Mark B.
So far so good. Seems stable
Renee S.
So easy to use and convenient. Didn’t have to lug the big cement blocks home!
William R.
Use of Tuff Blocks make deck building manageable, even for a 69 year old DYI’er. Building two 15’ x 15’ decks for a completed project of 30’ x 15’. Tuff Blocks helps to make the project a breeze. Thanks.
Robert M.
Here is my 16x16 deck. 1st deck build showing from beginning to end. Use these however you like. The product is absolutely amazing. Was easy to use, rock solid, consistent and the deck is absolutely QUIET and awesome to walk on. Thank you Build Tuff. So happy with the results. Robert from Indiana
Robert S.
My deck is a work in progress. I found the TuffBlocks to be snug to the wood members but not too tight. I did not have to fight to put the wood into the slots. I will be using them again on a much bigger deck in the front of my house. They have worked great so far!!
David D.
Tough block makes it easy to renovate and create. By using Tough Block I avoided filling my space with landscape material to build the deck I needed. Great product, thank you !
Travis S.
I really love these tough blocks! I built a 16x16 storage shed and my 4x4 posts fit perfectly inside the blocks. This is a great product for building decks, elevated tiny home frames, or storage shed. Worth every penny!
beth d.
Used your product to build a wood shed here in North Georgia. Used 4 pallets joined and mounted on your supports. Off the ground and supporting three full cords of wood.
James M.
Light weight and sturdy. I used them to support a 200sq ft shed.
Mike S.
The blocked worked out great and so much easier to work with than cement blocks. Very happy
david y.
Easy to work ..
Nacomas P.
Just what I need for my ground level deck. Fast shipping.
Jean D A.
This is so versatile, it is unmatchable!
David A.
I haven't used it yet but it's just the height I needed.
Beryl R.
They worked as advertised. Very light and easy to maneuver, move, relocate, etc. WAY easier to work with than the concrete block type. The finished deck (sorry, no pics) feels solid as a rock. So it did what I needed it to do for a bit more than concrete but MUCH easier and less frustrating to use.
Brian M.
Framed out 560sq ft of ground level deck with these things - made life easy! My first big DIY project on my house and I couldn’t be happier!
K W.
Very easy to work with. We used Tuffblock to build a low deck over existing concrete. Looks great
wolfece
Excellent for our floating deck. Lightweight and the joist fit perfectly. Made it easy to get a 16’x12’ floating deck up in a day.
Mac1
I recently used these to build an 8x10 deck about 1.5 feet off the ground, 21 TuffBlocks in total. It took a full day with two working, but neither of us had specific deck building experience. It's easier than digging holes for cement footings but still pretty tedious getting 21 blocks leveled and 21 posts set. Overall it seems very sturdy.
gayle
This item made it a lot easier to built a platform for a shed on uneven ground. Would highly recommend vice using concrete blocks.
Radols
I was looking for dimension of the concrete post block when I seen these items online. I was very pleased with the product ease of use, size and weight compare to it counterpart the concrete blocks. I would highly recommend these post bases for all your deck needs. Just looking forward to when they are available in your stores.
Hound dog wood shop
These make deck supports so easy and low profile. I got 20 for a walkway and landing. So much easier than hauling concrete blocks.
Ronka
easier and lighter than cement blocks thats for sure! Only problem is they stick out kind of far under the deck.
Paolillo
Worked great.
EB1959
Perfect for leveling a Shed deck! We had to build our shed deck on a slop and could not dig holes for posts due to rock, these made leveling it very simple! I built the frame structure, then used 4x4 treated posts to level the framing out. Good size foot print. I screwed deck screws into the sides at bottom, and I also drilled holes in the flat plate part and installed 12" "spikes" to keep the structure from possibly sliding.
Adam G.
I had to use almost 50 tuff blocks for a 230 sq ft deck. It felt excessive and notching out the posts for almost every single support was a pain. I think some additional resources on how to work with tuff blocks AND cement footings would have been nice. I know you mentioned that it can be done, but for a DIYer, a full set of instructions would’ve been nice. It seemed like the east choice to just do all tuff blocks, but unfortunately, I was a lot of extra work.
Maria N.
We used these to build a floating deck near a pool on a slight slope. This was on an upper level of the property accessible only by a flight of narrow stone stairs. I very much appreciated the weight difference between these and concrete or concrete piers. Definitely a back saver. Installation was straight forward and much simpler that digging forms. The lower profile allowed us to keep a cleaner line to the decking and save materials. The online support was also appreciated.
unhootchie
I built a front porch using pressure treated wood with trex slats to cover an existing cement stoop. I enlarged the stoop from 6x4' to 12x8' and used the tuffblocks on the outer corners. As others have said, you can't butt them directly against walls, but I don't know that it matters. Decking can have an overhang past the frame, which is what I did to make the porch flush with the house. They don't fit the 4x4" tightly, which is good. I was concerned that after leveling the tuffblocks, I'd have a hard time pulling out the 4x4 to make any adjustments. I am slightly concerned about a frost heave, but since this is a floating deck, it won't cause any damage if it slightly lifts in the front. Our winters are also mild.The reason I used these as opposed to digging footers is because we have a sewer access pipe to the left of the porch and we've been unable to get a clear answer as to where that pipe is under the ground. It was safer to keep everything above ground when working so close to that pipe. Now, having completed the project, if it holds up I'll be extremely pleased. Not having to dig holes and pour concrete saved me at least a day of labor.

John Z.
This is an amazing product. I’ve built 7 decks using them. I build alone, so it saves time and energy. It also allows to easily build low decks. I’ll never use anything else.
Reiner K.
This product is so much better than the brittle concrete bases we were looking at!!!
Richard T.
Was looking to build a low floating deck and these were perfect. Simple to use, light and solid. I highly recommend them for building a deck.
David P
Worked perfect as expected. Placed directly on dirt ground. Used to support a 8X10 wood base that holds a shed of the same size.
Citylightsdt
Worked exactly as they said it would. Real sturdy and very good quality. Used them to build an 8 x 7 foot shed on a cement foundation. Just need to make sure surface is level however you use.
AWalkInTheWoods
We had planned to use concrete deck blocks until we discovered these items. They saved us an enormous amount of labor. We were building a tent platform in the woods and this saved us from lugging those heavy concrete blocks. I couldn�t be happier!
Clark Sims
Tuff Blocks are very easy to use and every bit as solid as they are described to be. I will be using them again.
rich juzumas
I first used Tuff Blocks using them to build a small (6' square) deck to serve as a step up to an entry door. I had concerns about frost heaving causing movement and distortion but after three New England winters have detected none. The time and labor savings over alternative footing methods was very welcome. Last year my Covid project was to enlarge our outdoor living space, covering an existing patio and raising it with a 10' x 12' deck to match the height of an existing porch. The structure would have been designed differently using traditional footings to minimize digging and leveling concrete piers. Using span tables and TuffBlock's own recommendations I used a pair of blocks to provide ground support to each joist supporting the rim by short cantilevers. Using this method each joist had to be leveled from the fixed height of the porch deck, which is where the built in flexibility of TuffBlock to accommodate a 4x4 post came into play. In retrospect the hardest part of this project was finding the PT lumber I needed. With TuffBlock the structure can be easily modified or even removed in the future without permanent footings to deal with. Large decks would require caution not to exceed TB's load limits, but with appropriate design they can be the solution for decks up to about 16 x 16 and be incorporated in the design of larger, more traditionally supported decks, for example for changing levels.
JA
I am too old and too lazy to be packing around concrete blocks so these things are the perfect replacement. Got 'em holding up a deck and a couple small sheds and they work great.
Peter Mifsud
The Tuff Blocks were the most economical and time saving solution for our new deck, I would recommend them for any decking project
Kevin Fowler
Easy to use, quick to install. Two DIYers built a 10 x 19 deck in less than 7 hours from scratch. Used 4 x 4's to support joists, because ground was not perfectly level. Only way I see you could use the 2 x 4 slots would be if you were installing on a concrete pad or something PERFECTLY level.
Donna Attanasio
I used the BuildTuff supports under a small DIY shed over three years ago. They were much easier to use than sinking supports into cement. It took some work to get them seated firmly and level, but once we did, the rest of the construction went well. Most importantly, three years later, the shed hasn't budged an inch; it's still level and firmly supported. I'd certainly use these again.
Bryan Dailey
Easy to use and work well
DeckDan
Tuffblocks are awesome. I build about 15 decks a year , and these Tuffblocks make is so much easier than anthing I've used in the past.! Don't have to dig for 4x4 posts. Just level the ground and lay them down...super easy.
Marc B
Yes and my wife decided to build a deck on our own but we wanted to keep low to the ground. This saved us time and it's holding up perfectly. And yes they are pricey but well worth it.
EricM
I am the ultimate novice. I was so nervous to build my own deck but lot's of time on my hands. I was on the verge of buying the concrete blocks when I found these and watched the video. Could not have been easier. I had a contractor friend come buy and look at the tuffblocks before I did my job and he was blown away and is now using them for a deck he is building. Highly recommend!
Larry
All construction starts with a good foundation, I was going to go with the concrete piers which are heavy and not always cut very well, when I found these Tuff Blocks from Lowe. I bought 21 of the Tuff Blocks and I must say very impressed 4x4 posts, 1 inch lumber or 2 inch works great extremely light and durable. Your next construction project start with Tuff Blocks!!
rogerkk
easy to use. Used these for a footing base set on the ground for a 4x5 platform for our new above ground pool. used 2 against the pool wall and 2 stacked for the side away from the pool. fit a 4x4 good and feels sturdy.
Stanislav Havkin
A+++!!! Very ease to work !!! Like Lego !!! Recommended to everyone !!! Thanks !!! Stan.
Jason Hagan
This product definitely surpassed my expectations. I built a 10' x 10' deck and the time and money saved by using the Tuffblocks kept my project under budget. Shipping was extremely fast with zero issues. The next deck I am involved with I will definitely use Tuffblock again!
Sean Stahlhut
A great product. Made my life easy as a first time deck builder. We have very sandy soil in WA, so way easier than digging and using concrete. Very stable. Excellent cost effectiveness.
tim2
Great product, used as footing for 4 x 4 posts, for a deck about 18" off the ground butting up to a concrete wall. It makes leveling the joists easy. But you can't put support posts right beside the wall because the bottom surface is so wide it pushes the posts several inches away from the wall. Also if you use these to support posts at or near the edges or corners of your deck you are going to see them sticking out several inches beyond the edges of your deck. So I only used them to support posts on the interior of the deck and nail my joists to the posts. For the edges of the deck I had to use other supports because I didn't want black plastic sticking out beneath the edges. There is already a photo on here that shows them sticking out so I won't add another.
Donny C
Love them.lighter, stronger better then the concrete ones.
Bones
These are the best! Toss them down and build. Saved so much labor!
Lolo Bass
We are amateurs, and this product helped us build a professional-looking deck. It�s easy to use, they are lightweight, and using them ensures we ended up with a sturdy deck.
Bordoods
Easy peasy
Big O
Ordered them, they took a bit longer to get them than originally calculated but after I talked to someone, I got them quickly. They seem very sturdy and a great option for not digging holes.
James Ostapenko
High quality and easy to use product. Used >100 to build 50 sq/m deck. Deck is 18 months old, has not moved and looks great. BuildTuff team were amazing with their support, particularly discussing QTY and spacing for this huge project. Highly recommend!

Frequently Asked Questions (FAQ)
It is completely dependent on the project. As a general rule, if you’re supporting joists directly on the TuffBlocks, you will need to support the joists with a TuffBlock at every 4.92 feet intervals. Joists will need to be spaced at a distance appropriate to the finished material. For example; it is recommended that some decking timbers be spaced at 17 inches. It is always best to check with your timber material supplier for material specific recommendations.
Deck blocks were introduced over 30 years ago in the USA and since then, instant foundation blocks have been embraced worldwide for creating strong and stable foundations for both professional and DIY projects. TuffBlock's are an extremely popular alternative to digging holes, carrying heavy concrete blocks, mixing concrete and waiting for it to set. TuffBlock's are a versatile utility block and the options are endless for how you can use them to make completing your projects a breeze.
Yes. Especially when you consider the time and effort taken to dig multiple holes and then mix the concrete to fill them back in, not to mention the cost of buying the steel post supports and bags of concrete in the first place. Generally a steel post support and two bags of concrete will set you back around $24-30 USD. Even if you use a few more TuffBlocks, you are still well ahead of the old conventional footing method.
TuffBlocks have been engineered for structures up to 36" above ground. Having said this, many people have built structures higher than this using the composite foundation method (TuffBlocks in combination with concrete-in-ground footings). We recommend that you consult with a qualified builder or engineer regarding your project.
TuffBlocks have been engineered to be stackable and only weigh 1.5 lbs each, compared to that of a traditional concrete deck block that weighs 41.5 lbs each!
Made in America for professionals and home improvement renovators. Each TuffBlock is incredibly strong, with its vertical load designed to support up to 1,700 lbs and is break tested to 11,000 lbs.
Great question and yes we do offer a Buy Back Policy for remaining TuffBlocks not used at the end of a build!
