Love the big foot in the background at 6:59. So funny. Watch again if you didn't see it.
Nobody talking about the sasquatch out for his morning walk at 7:05?? Fun easter egg. Gave me a chuckle. Thanks.
He's out there!
i was mad because the type was too small to read without full screen, and the vid didn't answer a particular question i had, but Bigfoot randomly walking by made this all worth it! Hahahaha I love the sense of humor
We're sorry that your question wasn't answered. What was your question? We can most likely answer it here.
@@WesternInterlock I just want to know who is in the costume!😁
How do you know it's a costume? 🤔😉
@@WesternInterlock Fair, either way I want to know who they are, and see if I can get them in one of my videos, feel fee to pass on my info if you know them personally! 😁
Viva la Sasquatches!
LOL, I love the gorilla that walks through the background at the end of the video! Agree with other comments here. Very clear and nicely paced.
Thanks for watching!
Very nice tutorial video bordering on perfect. You are an excellent communicator. Pacing, clarity, diction, voice, succinctness, verbal instruction related to exact video example was excellent. You did so much right in this video you made it feel like you did nothing at all. Thank you for showing us what an excellent video looks like. Most of youtube shows the opposite. Plus your overlay expertise effortlessly shone through as well. Thank you for a super excellent job! 1st rate paving skills. 1st rate video skills that include 1st rate communication skills. MUCH THANKS!!!
Thank you! We strive for perfection!
Your comment is a very nice compliment! Please email sales@westerninterlock.com. We would like to thank you with a gift!
I liked this video for the Sasquatch. Well done!
Thanks! He's out there!
wow man....glad I found this video I think im gonna tackle my back patio.......
Awesome! Best of luck! You can do it!
Love the Yeti in the background!
We see him often around our job sites…
I like the BIGFOOT in the background!!
It’s been hanging around our projects lately.
One of the prettiest parts of my house. Is the paver steps to the front door. 😊.
excellent video! the bigfoot sighting was a bonus!!
Thanks!
Great video! I love the idea of the facing stone - as our posts are right at the edge of the porch. We have a brick house wall on the porch and are not sure how pavers will look with the brick.
If you choose the right paving stone it will look great!
Hahahah, did anyone notice Sasquatch walking in the background between 7:00 and 7:10?
Nice easter egg!
The DIY Bigfoot has been hanging around our jobites. Keep your eyes peeled in our other videos.
@@WesternInterlock Love your sense of humor.
LOL! I just watched this, how many people noticed the guy dressed as Big Foot at about 7:43 walking down the street in the background! lol! good video, I didn't think that adhesive would be strong enough to hold
You just gotta believe
Thanks for gr8 how to !!!
We’re glad we could help!
Was Bigfoot just passing through or does he (she) live in the area?
Supposedly our video fell right over the start of Bigfoot's migration from the Gifford Pinchot National Forest down to the Siskiyous. So we must've filmed one that was lost and wandering around. 🤷♂️
Ha - I was thinking the same thing
Thanks for a great project vid. I have an old patio that has some minor cracks and does not have proper drainage (not terribly off, just some pooling). How do you recommend correcting that with an otherwise very similar project? Also, Bigfoot gave my boys and I a pretty good laugh!
Any imperfections in the existing patio will transfer directly to the new surface eventually. If there's poor drainage, the best solution is to remove the concrete and replace it with pavers.
Have the contractor install a channel drain at its low point.
hi! I saw that the border was glued to the face block and the concrete slab. Then the pavers were laid on top of the slab + fabric + bedding sand. Isn't there going to be a height difference then? Did the thickness of the adhesive compensate for that?
You are right. There is an infinitely small height difference. Taper off the sand at the edge to minimize it, and you'll never notice.
Love the guy in the Bigfoot outfit!
About 2 minutes of this video is informative..
Amazing videos just wow. CAN YOU PLEASE DO interlock stairs video . How to build interlock stairs video. Please
It is on our list for videos for this year.
The outside edge is pressed into the soil and stacked up to match the porch height. The porch slab has a completely different foundation that's not tied very well to those outside stones. Even with the adhesive, won't those outside stones shift after a few heavy rains and freeze/thaw cycles therefore distorting the outside perimeter?
Good question, here in our climate we have no freeze thaw that would push this method to its limitations. We do however have a very consistent amount of rainfall in our region and with the porch mostly covered and facing the North, it hasn't seen much of it. This is just a pretty face to help tie in the style of hardscape a little better, we do not think it is making a dramatic difference in the weight of this slab to persuade it to move, settle, or separate any faster than if it was left alone.
why dont the inner pavers sit higher than the glued pavers since they have fabric and sand under them?
Very nice! 👍
Will this hold in cold winters?
If you use the correct adhesive it should work fine!
Why did you start with the border? Wouldn't it be easier to start at the house and work your way out?
Because the edge of the existing slab is an absolute, so it takes any guess work out. Additionally, it always looks better to have any cuts up near the house, partially hidden by the siding.
This is a helpful video! if the concrete is new, do you still need to put down sand?
The sand helps take up any irregularities in either the concrete or the pavers, so technically, no, but it will make your life easier.
Is it possible to lay over a concrete slab like this with bluestone and dry-lay it with stone dust/no mortar? Then fill the gaps with polysand. I have a slab as our back patio and would like to cover it with bluestone. Thanks!
Technically it’s possible, yes. But we aren’t experts on natural stone so I’d recommend talking to a mason.
That's gorgeous
Thank you!
Great video. Very informative. Any recommendations for a contactor in So Cal Ventura County area?
Unfortunately, the closest that we get to your area is Sonoma County, so I don't really have a good answer for you. I would recommend checking with paving stone suppliers in your local area.
Nobody mentioned Bigfoot walking down the street at the 7 min mark? LOL
He's out there
7:05 lol there is a grown man dress up in a bear costume walking in the back lol
When you laid the polymeric sand did you run a compactor over the pavers to get down in the joints? Or is this not necessary with the thinner pavers?
On an overlay, the compactor is likely to break the pavers, especially the thinner ones, so, no, we did not compact the stones.
Is it possible to lay a walkway using pavers directly on top of creek sand or basically just sand? I feel like pavers will always move up and down over time.
That is not advisable. Sand is pretty much impossible to pack and will always move. A properly compacted gravel base should never move very much.
Anyone going to mention Bigfoot walking down the street lol.
Apparently, this is one DIY Bigfoot. He's been lurking around our jobsites lately. Keep your eyes peeled in our other videos.
Very nice job. I have a 10x10 raised covered concrete porch in our backyard and would like to do the same. Couple of questions if you don’t mind. I have large exposed aggregate (larger than it appears you were dealing with here). Would you recommend grinding it down to a somewhat smoother profile? Also, how do you deal with water drainage. Some of the manufacturer installation instructions I have seen recommend drilling weep holes in the slab. Thank you.
Both wouldn't be a bad idea. Obviously, the flatter it is, the better off your end results will be. We couldn't drill weep holes here due to the thickness of the slab.
@@WesternInterlock Because the slab was too thin or too thick?
Too thick. We also weren't too worried because it was a covered northern exposure and won't get much direct moisture.
There was no Bigfoot harmed in the making of this video😂
I'm just here to let you know you captured a sasquatch in the background of you video. lol
He's out there
Great video! I have an exposed aggregate walkway where I plan to do the same kind of overlay job. Temps here in the Philadelphia area can drop below freezing. If I use a flexible tile adhesive for the border pavers, will I be ok? I am assuming very minimal water passing through the tight joints and poly sand of the other pavers.
We can't really speak to that because we have a totally different climate here. We'd recommend going to your local hardscape supplier and asking them.
What would you do if you wanted a half inch spacing between the bricks (including the glued down edge pieces)? What would you use to join the border bricks? Mortar/grout? I can't imagine you could a poly and for the vertical face.
That sounds more like masonry, which is out of our wheelhouse, so we can't authoritatively answer. Interlocking paving stones use their close proximity to each other to provide the necessary strength. We would recommend asking a mason.
great video. Question about the border pavers; i see the interlocking "nubs" are exposed along the outer edge. To me, it's not a clean look. Do folks just leave the nubs there, or have folks shaved or ground them down so the edge is relatively smooth?
People have shaved them off with a saw or ground them down, the only downside to that is that then it exposes more aggregate and doesn't look as clean. We used 40mm pavers for this overlay, but if you used standard 60mm you could use a coping like our Monaco for a cleaner look.
@@WesternInterlock thanks! how would I grind it down (what tools?)? I'd like to at least try it on a couple of pavers and see how it looks.
You can use a diamond cup wheel (www.amazon.com/KSEIBI-644030-2-Inch-Diamond-Grinding/dp/B01N5EI8F3) on an angle grinder. Be sure to wear some sort of breathing protection because there will be a lot of silica dust. The other option is to use a tile saw (or equivalent) to shave them off the edge.
@@WesternInterlock Awesome thanks!
Is it better to over hang the border like u did over the side facing block then to take it right to the edge?
That's more or less up to your personal preference. We like it when there's a little bit of a reveal.
No tamping needed to settle sand and eventually compact pavers?
You can hand tamp if you really want to, but it's not necessary since it's overlaid on the concrete slab on a very thin layer of sand.
@@WesternInterlock thank you!!
I did not understand what was the reason that you did not glue all the Pavers like you did with the first row , is that a problem with water or sun or leveling if glued?
Thank you
There's no real reason to glue them all. The outside edge holds them in place, and they're not going to fall up, so there's no reason to glue them down. Conceivably, you could glue them all down, but it would be cost prohibitive and take a lot longer. Once the outside it is restrained, those pavers aren't going anywhere. Pavers are a flexible system as well, so gluing them down would eliminate that benefit. If they're not glued down, they are allowed to move ever so slightly to accommodate environmental changes.
@@WesternInterlock understood. Thank you
Did anyone notice big foot walking across the street towards the end of video when he was washing down patio nice, work by the way.
He’s been hanging around our job sites….
Can I do this and continue my pavers into existing yard without concrete… so tie in from concrete to dirt area?
Yes, it is possible to tie in an overlayed area with an existing dirt area. You just have to be very diligent with getting the base compacted to 99.5% proctor density so there isn’t any settling.
Where do you buy such thin pavers
We sell 40mm and 50mm pavers.
westerninterlock.com/products/cobble-slimline/
Awesome video! What do you think is the best option for me using 18x18 pavers over concrete? Sand or mortar them?
We prefer sand-setting pavers because it's a lot more flexible.
@@WesternInterlock thanks for the reply, I want to do a grout line between my 1" pavers do I use polymeric sand for this "grout "line
For the sand between the joints we would recommend Extreme Wide Joint Polysweep.
westerninterlock.com/products/polysweep-x-treme-wide-joint-sand/
Yes. Use a polysand approved for wide joints like SEK X-Treme Wide Joint or Easy Joint.
@@WesternInterlock thanks so much 🙏, 1 more question, if all my pavers are 1" thickness and I just glue the trim piece all around perimeter area, wouldn't the rest of the inner pavers sit higher bc of the sand? Thanks again for the replies
The house has settled quite a bit over the years. The patio has a crack that runs along the wall, about a meter away from the wall. How should I prepare it before putting down pavers? The crack is about a 1/2 inch wide in some places. A gradual slope in the right direction.
Your patio does not sound like a good candidate for an overlay. At this point in the game I think your best bet is going to be to rip it out and start over.
Where does “sealing” the pavers come in and do you always do it or not and recommend brands? Thank you for video!
Sealing is the last step of any paving stone project. Whether or not to do it is completely up to you. There are several performance benefits with sealing such as less moss and weed growth, protection against stains, and color enhancement. The main drawback is that you can royally mess up your pavers if you do it wrong. You can watch our video on sealing here: ruclips.net/video/xNOVhidoJiw/видео.html Here in the PNW, we recommend using solvent based sealers made specifically for paving stones such as SEK's 8700. They hold up best in our moist environment. If you live in a drier climate, you may be able to get away with using a water based sealer. What ever sealer that you choose, just make sure that it is a sealer formulated for paving stones, not one made for sealing concrete. They are different products all together.
Would that adhesive work on a painted concrete patio? Or would I have to grind down to bear concrete? Thanks
It would be better to grind or strip the paint off. You will get better adhesion on clean concrete. If you grind, it wouldn't have to be totally polished or anything. Simply roughing it up so the glue can grab is enough.
dude, think i’m the only one who saw. but sasquatch was behind you
If you have glued the outer edge down how down water drain away from the inner field pavers?
If you notice, the glue is not a solid line. It is well within the edge of the paver which allows the water to escape.
love the gorilla
So I want to do something similar to this but I want to match the brick I already have on my home and only do the front of my front patio that is made of concrete. If I only add the brick to my exposed foundation do I need to dig that deep around the perimeter?
No you do not. We just did it to hide the exposed aggregate of the underlying porch.
Good job 👍
Thank you!
Ok question, if the border paver and the interior paver stones look like same height why wouldn’t they be higher then border after laying down fabric and sand? Can’t rubber Mallet the concrete not going to give?
You are correct. There will be slight lippage at the edge where the interior pavers are slightly higher than the border. We recommend tapering off the sand at the edge if at all possible to keep this to a minimum.
Where does the water on the interior on the fabric drain off to if the border is glued to patio
great video but I don't see anyone commenting about a sasquatch/bigfoot casually walking behind and crossing the street at the 7:00 mark =)
We do live in the PNW you know! Who knows what's out there?
If you want to raise it higher, could you use 3/4 aggregate a few inches over the concrete?
If you were going 2" or more, you could use wall block around the outside edge to retain the 3/4-0 aggregate. Less than that would not be a good idea.
Hello! What type of geotextile can you use? Would it be ok to use black landscape fabric that comes in rolls?
If you mean the felt-like weed barrier, than no. We recommend a woven geotextile like Terra-Tex. hanesgeo.com/Catalog/FeatureComparison?id=2841 It comes in rolls and should be available at any landscape yard.
Hi..I want to just use glue on a new concrete patio to overlay pavers. What precaution I need to take.
There's no need to use glue to hold all of the pavers, just the outside. The middle is held by the outside and it can't fall up, so there's no need to glue those. The sand is there just to make up for any height variance in the pavers or the slab itself. I wouldn't recommend gluing all of them. It will greatly increase your work if you ever needed to do anything to the pavers and it will not allow the pavers to move at all.
@@WesternInterlock I am planning not to use sand for the field pavers, because I am the only person to work on it and its a big patio around 800 sq ft. My concrete patio is still to be built. I will get proper slop for drainage also, I am thinking of having concrete grid lines closer than normal so that drainage will not be a problem. Also I will use polymeric sand for sealing. Do you still think I can lay field pavers without glue??
What make paver stones did you use on the borders?
Those are our Slimline Cobble pavers, which are the same pavers as the field, only in Charcoal.
Thank you!!!!
You're welcome
What type of sand do you recommend using over the filter fabric?
We recommend ASTM C33 washed concrete sand. You should be able to get it somewhere in your area.
Hi - I have a geotextile woven fabric from sandbaggy. I don’t believe it’s permeable, is that ok to use?
It would be better if it was permeable so that any water isn't trapped.
What can I use to fix the slope of the concrete? Does that go before the fabric?
If the concrete is sloped bad enough to require fixing, the amount of work needed to make it level will make it almost just as easy to remove it and lay pavers the normal way. You can use self leveling concrete, but that requires exact following of the instructions or else you can have it fail. You'll also need to build a form around your slab to hold it in. It's just not worth doing.
Hello,
Would this installation method work for porcelain pavers as well?
We can't really speak to that, since we don't know anything about porcelain pavers. We recommend following the manufacturer's instructions.
Bigfoot approved
Good job but the volume is extremely low.
What kind of mortar did you use to level the paver on the walk?
I believe it was standard Type S mortar mix.
How did you conceal the exposed mortar that you would see after that block was placed? Also the blocks can settle before that mortar dries. How do you prevent that from sagging
.what stones did use?
These are our Cobble Slimline pavers. westerninterlock.com/products/cobble-slimline/
Can new pavers be laid over an existing bluestone pool deck?
Hypothetically, if the bluestone was mortar set on concrete you could. However, if it is sand set, you will be placing a flexible surface over a flexible surface and the results will be disastrous. Regardless, we would recommend pulling up the bluestone and starting fresh from the base. The time spent will be worth it in the long run.
Lovely work, only problem I could see is when you laid the concrete block flat 9" then put concrete block on its 4" because the flat block wasn't laid In concrete over time the bottom block WILL start to sink in existing mud, which will then make top block sink too
That's why we added a gravel base underneath. We haven't had any issues with properly based projects in 30 years.
Is that a Yeti behind you at 7:00 to 7:07 ??
He's been lurking around our jobsites of late. 👣 We're in the PNW so I guess he's a local...
Haha! Sasquatch... Nice touch.
Great process, love it. I don't recall seeing the landscape fabric being installed over existing slabs before, I do like it, I can only hope it doesn't make too much difference if it was not actually installed Since I can believe that a lot of installations out there already are missing this important step.
what adhesive did you use
We used SEK Surebond SB-20. It's our favorite, but any flexible exterior grade concrete adhesive should work if you can't find it in your area.
Nice video. However, sand and paver on a verandah ... maybe better to mortar onto the concrete
While you can mortar set pavers, it's not recommended. There's simply no need, and it can adversely affect the product. Refer to the last several paragraphs of this white paper for the reasons why: westerninterlock.com/wp-content/uploads/2023/03/WI-Mortar-Set-Pavers-Whitepaper.pdf
@@WesternInterlock I hear ya. The flex and competing strength issues are real problems in thinner substrates, and I guess even more so as the tile is increasingly porous, like in a red brick tile. The tile will ultimately lose. Good points.
Is anthing between the pavers, or are they just pressed together. Or does the sand fall in between.
I was trying to understand why you pit sand over the top.
I have a stained concrete (a bad job).
Thanks for reply.
The sand dribbles in between the pavers and effectively locks them together, making one cohesive whole. For a photo of this interlock, check out this post on Instagram: instagram.com/p/Bwkv0EbFtN7/
And it's a different type of sand for on top
@@ingeniouswit thank you friend
would use a tile adhesive with flexibility to put the charcoal edgings on with 👍 never use that C31 mastic one big frost it start moving about 👎 but is everybody own way of doing it 🤔
We don't have the frost issues that you do so it's not a problem. The SB-20 we're using here is a great product. We haven't had any issues with it here in the PNW.
What the hell was that walking past in the background at 7.05??
Bigfoot?
How thin should the sand be
As thin as possible. The goal of the sand is to level out any imperfections in the concrete. It really just needs to be a skim coat. I think we put down 1/8".
Big foot sighting !
🦅👀
What is considered a “small amount” of paver sand? Is there a minimum you would suggest? I have to meet a bottom step to meet with pavers that is already low allowing only for 3/8” of sand.
Basically you want as little sand as possible. We use only 1/8" of sand for this. The purpose of the sand is to help even out any imperfections in the concrete and pavers to give a consistently flat finished surface. Additionally, if you have too much sand, it can make your glued down outer layer much lower than the field and the resulting lip will be a cosmetic flaw and a tripping hazard.
Am I the only one who saw "Bigfoot" walking in the background at 7:00? I knew "Bigfoot" was real!
All you have to do is believe.
Can't you just glue the pavers to the concrete slab?
In theory you can, yes. The point of putting the sand underneath is to allow for any surface imperfections in the concrete slab. If you glued them straight down, anything that is imperfect about the slab will telegraph right up through the pavers.
Should have used a bullnose paver for the edges exposed pavers to me doesn’t look to appealing 😮
We would have if these were 60mm pavers. However these are 40mm pavers designed specifically for overlays so that won't work.
I saw Big Foot!! hahaa
Is no one mentioning the bigfoot sighting here?
You just have to believe
Just my opinion, but, I would have just mortared the interior pavers in and avoided using the Geo-underlayment .😊
The reason we refrained from that method is the added thickness, and weight. We use a Geo-filter fabric to create something that can separate the concrete paver from direct contact to the concrete surface as condensation between the two can accelerate efflorescence. This is also why we try to steer from certain types of mortars to adhere them to a concrete surface. If this porch was not covered we also would add 3/4"-1" weep holes every 6-8 square feet to reduce condensation which can be dramatically increased by rainfall from above as all concrete surfaces dry through the top, also increasing the risk of efflorescence. These are all preventative measures, not guarantees.
Was it just me seeing a person walking in the back round across the street in a BEAR suit
It's the DIY Bigfoot. He's been hanging around our jobsites lately.
looks great, can't hear a thing.
We're sorry about that. We'll be adjusting the volume in subsequent videos.
Did everyone miss bigfoot in the background??
You just have to believe.
is that bigfoot?
Perhaps!
Sasquatch @6:57. That's what happens when you build housing developments too close to the natural habitats ! ;-)
He's out there!
Audio too low even on high.
Yeah, we're sorry about that.
Without doing literally everything else, the driveway and walkway looks like crap
Uh, Bigfoot?
Eagle eyes! 🦅
I think I saw a Bigfoot
You may have!
Big Foot
Bigfoot abides.
I hate concrete 😊
Guys, if you're gonna make a video, at least make it audible.
Yes, we are aware of the issue on this video, and have adjusted it for subsequent videos.
