On today's video, we talk about HPB or High Performance Bedding, what it is and why we use it as our bedding layer instead of concrete sand.

I've been useing 3/4" clear and then used HPB before paving any patio stones for a little over 10 yrs and I recommend it to my friends who want to pave their walkways and backyard.

Hey what base do you recommend for a 2" flagstone patio in Ontario? 3/4" Clear then HPB? Will be doing one in a new video! Thanks

Man thanks to Mike and his/this video it saved my bacon today. I originally bought a load of HPB from a well known local building supply store (no not one of the big box stores). I ran out do went to another supplier very close to my house and picked up another load. BUT, after watching this and other of Mike's videos, while not a pro, I've done enough homework and research to know 1/2 of the garbage I put down was not the recommended material. Too many rounds and it felt like I was walking on a pebble beach with my feet slipping under me.
After checking in with Mike, he graciously advised Absolut don't use that material. So my instincts were right.
That $150 of material could've ruined my entire patio. 😢 But as we all learned in Star Wars; trust your instincts, you know it to be true.
Thanks Mike 👍

I am just about to screed a small patio in my yard. This video has convinced me to use the HPB over a concrete sand. You mentioned it would sink a bit, but I am assuming for a small patio, this would be negligible?

Been stonescaping for 20 years. I’ve always used 3/4 clear under all my armour stone walls and natural steps. Not one complaint of sinking (over 900 jobs)
HPB is the best for paver projects

Discovered your channel a bit too late and have already installed 6” of dense graded base, the 3/4”-1” minus. The area does get water runoff as the yard has a slight grade toward where the patio will be located. Planned to use sand, but would you recommend using this material as a screed layer instead even over the dense graded base? After watching your videos, realizing this may not have been the best choice for a base layer, but it’s already in the ground and hoping to get things right for the next step. The pavers will not be permeable, if that matters—using Unilock Beacon Hill smooth pavers. Thank you!

I tore up a concrete walkway and will be installing pavers. I will be installing pavers and want to know if HPB can be used as base layer and bedding layer.

[mauielectriccruisers]

It’s a wealth of information, to a novice like me, it’s coming at me too fast, almost overwhelming..

[jasonberezny]

Excellent presentation. From Ontario Canada. What is the standard depth required for base using hpb for bedding? Is a sub base of granular of 4-6” needed? How deep does the base excavation need to be for a common residential patio, walkway installation?

[basemtemraz]

Hi,
Thank you for the great videos. I am putting up a raised patio. I excavated about 12 inches. I have put in 6 inches of aggregate A and add 4 inches of HPB as the bedding layer. How much should I compact this layer ? The aggregate A was compacted with a vibrating plate, should I do the same with the HPB? Also should I use a synthetic layer on top of the HPB to prevent shifting, and future ant colonies?

[yzebrov]

So your using the HPB instead of the 1” sand layer that would be right underneath the flagstone? Or are you using it instead of the 4” base rock?

[carrieleedinsmore]

Hi! Why do you not recommend using HPB for the entire base? You said you did for the one walkway, but haven’t since. Could you elaborate on why you do not? Thanks!

[JoanneLozier]

We plan to fill in our inground pool and lay a patio which, when finished, will extend just a few feet into the shallow end of the pool. Our landscaper suggests using HPB to fill in the void in this area, but we aren't convinced it will be enough to prevent a significant sink. Three feet of HPB?? Also in the GTA. Is it as good as all that?

[nellyjizzle]

Final Height question: do you get any paver settling during poly compaction with HPB? Like with sand for example, it compacts about 1/4".

[cestavendre]

I have a small question, because I'm a bit confused, and I want to succeed in my installation next spring. For 3/8 rock bedding, is it better to compact it or not?! thank you a thousand times!

[dylanbrown]

For a walkway/patio extension.
Weed barrier
HPB (tamped or no tamped?)
Synthetic paver base
Pavers ?

Does that make sense? Sorry first time DIYer

[jorgemoreno-nunez]

What would you choose: 1/4 clean crushed rock or 3/8 clean crushed rock? These are the options available where I live. I'm planning on using a synthetic base for our backyard pavers under our deck cover

[adamarriaga]

I just want lay few pavers in my front yard and stop stepping on my lawn grass but i want to do it right! A little advice please

[Nightside]

I called several building supplies... they never heard of it in los angeles area. Just sand. Checked prices😲

[troyporter]

So how exactly do you handle the jointing sand going down into the HPB? compacting and just keep adding more until it stops?
