About This Product

For many homeowners, building a paver patio or walkway is simply too big and arduous a project. Lots of dirt, digging, hauling and labor. If you ask, most would say, I'll never do that again. Not anymore. Brock PaverBase is a lightweight panel that replaces bag base and most of the sand used in the "old way" of doing things. Now you can build the patio or walkway of your dreams in a weekend without all the sweat and fatigue. Brock PaverBase offers many advantages over traditional project base construction.

Highlights

  • Lightweight and durable material makes it easier, faster, and a better way to build your project base, and it costs less
  • Each 5 sq. ft. panel (1 lb.) replaces 4 bags of base (160 lbs.) (1 case = 20 panels, weighs 20 lbs. covers 100 sq. ft.)
  • Simply lay the interlocking panels on top of sand layer and you have a stable and accessible job area, which speeds up the process of laying pavers
  • Digging out only 3 in. or less with Brock paverbase Vs. 6 in. to 8 in. with heavy bag paver base makes the job a lot easier
  • Patented product lifetime limited warranty
  • Product Height is .68"
  • Use for all paver and patio stone projects (patios, walkways, pool decks, sitting walls, pillars, grills, small and large (foot traffic) for professional results, not for driveways. Can also use under turf.
  • Able to walk on panels while installing pavers and patio stones
  • High grade 100% polypropylene is proven as a construction material and provides lifetime stability for your patio
  • Use in All Climates (U.S and Canada) cold, hot and especially in freeze thaw regions
  • Channels and holes allow water to flow through the panel into the sand for drainage to avoid ponds on your patio
  • Medium density material is easy to install and cut with utility knife
  • Great for installing irregular shaped stones or multi paver patterns; you can move your pavers around with ease to match your pattern
  • Food grade material is environmentally safe, does not leech chemicals into the ground
  • How many panels do you need, project sq. ft. / 5 = number of panels
  • How much sand do you need, project sq. ft. / 12 = number of bags (for 1/2 in. sand depth)
  • Takes all the hard work out of preparing project base

Questions & Answers

Can you use this to Top and smooth out 57 gravel rock base that has been leveled for 5k pound hot tub?
ByOct 29, 2026
1 Answer | 
Answer This Question

57 Gravel has almost no fines, so after you lay your long lasting landscape fabric, I would screed 1" sand and hand tamp. Use a straight edge from high to low end of slope to make sure there are still no low spots before laying you panels. Regarding the 5k hot tub, there are a couple important things to consider with hot tubs. 1) Is the hot tub built with equal weight distribution over the entire bottom surface or is it framed where all the weight is on the frame, outside area? 2) Can the paving stones handle the weight of the hot tub? 1) Equal weight distribution: You can use the panels if your paving stones can handle the weight. Most paving stones (patio stones, patio pavers) do not have any required specs. The only ones that do are driveway pavers for vehicles (8,000 lbs./ per sq inch). 2) Framed hot tub, weight not distributed: There are two ways to prepare base under hot tub. Use traditional base under hot tub and use Paver Base panels for base for the patio or walkway leading up to or around the hot tub. Use 1" of base material for additional support, use Paver Base panels (following steps). You may get some compression of the panel, some amount under the .68" thickness, which you may or may not notice. Again, make sure you use a paving stone that can handle the weight.

      I used brock base under my patio pavers & spaced them apart for decrative rock trenches between them. In the center I left it open for a water fountain. It's very heavy... total over 400 lbs. Is the brock going to support it?

      Answer This Question

      The PaverBase panels can handle up to 8 psi, so the answer depends on the size of the fountain base. Questions call Tim - The PaverBase Guy anytime at 813.431.8259

            Do these prevent sinkage
            ByMay 21, 2026
            1 Answer | 
            Answer This Question

            No not when the panels are installed correctly. Compacted ground with proper 1/4" per foot slope and use a straight edge or side of straight 2x4, in the direction of the slope, to fix all the high and low spots. This is important as the panels conform to the ground. Questions call Tim - The PaverBase Guy anytime at 813.431.8259

              Works for me on a 260sf area, just make sure you add enough slope to control water flow. Also when leveling sand with pipes, take time and use level to make sure you get the level and slope you want, here is where i wish i would have paid more attention. I used a Block and Paver saw from Home depot to make my cuts.

              light, easy to install, stable to use
              I bought these to do a little patio out back behind my new-to-me mobile home. I thought they'd be easier than shoveling and moving and leveling gravel rocks and boy was I right! The installation was sooo easy and the lightweight panels let air and rain drain up/down through while we were still work, but now that I have the bricks all laid on top, it seems pretty stable. See photos of installation process to see what I mean. I used the lightweight plastic horizontal edge restraints THD sells to take down the panels and use as a base for scalloped edgers and that worked great too. The Brock panels made this project a LOT easier to set up, adjust (repeatedly) and finish!

                Not as easy or effective as advertised
                I purchased the Brock 20 in. x 36 in. Black Polypropylene Paver Base Panels (20-Case) to build a 12 ft × 11.3 ft paver foundation for my aluminum shed (about 300 lbs). I chose this product because the video made it look simple — “five easy steps” to complete a patio base. Unfortunately, my experience was the opposite. The process was very difficult, time-consuming, and the final result was disappointing. 1. Installation is much harder than shown The instructions say to remove grass, compact and level the ground, then add ¼"–½" of sand and level again. In reality, achieving that level of precision (+¼"/–¼") is nearly impossible, especially over a large area. Even a small stone can throw off the level. I spent weeks trying to get the ground right and still couldn’t match the tolerance they claim is easy to achieve. Because of this, the sand layer inevitably ended up thicker than ½", making the surface uneven. 2. Panels are not as stable as expected After placing the panels and laying the pavers, I followed the instructions for applying joint sand, which required gently tamping the pavers. Even though I was very careful, the panels flexed slightly because they sit on sand. This movement caused several pavers to crack, and I had to replace them. 3. Foundation did not stay level A few months after installation, I noticed that parts of the foundation had sunk slightly. This seems to be caused by unevenness in the ground and sand layer beneath the panels. Despite doing my best to level everything, the foundation did not remain stable. Overall: The concept of lightweight, easy-to-install base panels sounds great, but in practice, it didn’t work well for me. The precision required for proper leveling makes this product far more complicated than advertised. I would not recommend it for larger projects or heavy structures.

                  We reset the paver blocks in the courtyard and used these Brock paver panels as a part of the system in hopes to stabilize the blocks from dropping and moving away from the concrete sidewalk surround. Which has continued to happen time and time again in the past. I ended up cutting these panels in half to match the paver block sizes better and get more bang for the buck since these sheets are not exactly cheap even in large quantities. But if they hold the paver blocks in place for a few years it would be worth the investment. With the paver panels, sand and some edging and spikes I think the paver blocks are pretty solid and are staying flush to the concrete. I would use these again although in my opinion the price is something to consider if you have a lot of blocks.

                  The pavers were very easy to install and cut as needed. I bought 3 boxes and using these pavers made the process shorter because of the length…

                  If I could give it a -10 I would. Biggest pain ever. Extremely difficult to work with. Let’s say nightmare. I may be having it ripped out & re-done. Absolutely worst experience even other than torture

                    These were great to use! Easy to score/cut. And saved us a ton in materials and labor for our brick patio! My parents have a small project to do and were quickly interested in how I completed my patio and used these, saving them several trips for materials and cost as well. And now that my little sister saw I was able to do a large DIY patio, she's also attempting to recruit me to help her with a walkway as well. Would highly recommend to any DIYer.

                      First time paver installation
                      This was my first time installing a paver patio. Having to dig down 8in+ and hauling in gravel didn't sound appealing. The section I installed is 8x8 and I completed it in 2 days, the slope on our yard was a challenge so the first day was figuring out the best placement and removing dirt, second day was laying the pavers. These made the job surprisingly easy.
