TRUEGRIDPRO LITE Permeable Pavers Designed as Driveway Pavers, Grass Shed Base, Patio RV Pad, Gravel, DIY Outdoor 120,000 lb Load Class Pack of 18 (72 Square Feet)

I purchased this product to construct a patio in place of a hot tub which I had removed--initially I was looking at concrete pavers, but I have 3 mature trees near the spot and the roots are way too dense to dig a conventional foundation. With these, I just graded the site roughly level, laid the tiles down, dumped gravel in, and raked it in, just as advertised. This product, half a cubic yard of pea gravel and a bit of landscape fabric, a wheelbarrow to get the gravel from my truck to the site, and a couple basic tools to spread the gravel really was all that was needed.I wasn't sure what to expect with respect to the surface--I would have imagined that pea gravel would shift underfoot quite a bit, but with the grids in place, standing on it definitely feels very planted. It definitely exceeded my expectations in that regard. The plastic is very thick, and quite sturdy, and the tabs snap together securely but don't require tools to click into place (which is impressive from a manufacturing tolerances perspective). If you need to cut the tiles to make a more complicated shape, you probably can do that, but power tools would likely be required. At about $2.50 per square foot, the price seems steep, but I think they're going to be worth it in the end.Overall, as of the day after the install, I couldn't be more pleased. I'll update the review if that changes, but as of now, it's great.

So far, I have used it in three applications. One was in front of a shop in my backyard where water stood after a rain. I put a layer of white rock, then the TrueGrid Pavers, and filled them with angled black rock. No more water problems, and looks good. Had a number of tree roots I had to work around, and the TrueGrid pavers were easy to fit using a skill saw.The second application was on a walkway to a grill in my backyard. As the walkway approached the deck the grill sat on it sloped down. Problem - this would accumulate water. Put the TrueGrid pavers down, and again cut them easily to fit the form of the walkway. Put rubber pavers over the True Grid pavers. Ended up solving the water problem by lifting the walkway and yet providing drainage since the TrueGrid pavers are about one inch. Used no gravel in these and yet the walkway over them is solid. You would not know the rubber pavers were not on solid ground.The third application was to extend my driveway. Again, the problem was drainage, and in this case, if cars parked there, ruts. I had thought about using regular pavers, but there are are a bunch of roots and I would have had to dig deep enough to make a base of sand for the pavers and the width of whatever pavers I used. Digging down through roots three to four inches did not sound appealing. With concrete, again there is the problem of digging far enough down to lay a good base and use either wire or rebar. Then there is the work involved in mining the cement. Using the TrueGrid pavers I only had to go down one inch, level the ground, lay the pavers on it and fill them with angled black rock. Works perfectly. Heavy pickups can park on it with no. give, no ruts, and yet it allows excellent drainage.Glad I found this stuff. I have some other projects I intend to use it on. Check out their web site for examples of personal and commercial use and it will also give ideas as different ways it can be used. No, I do not work for them nor receive any compensation for this review - it's just good stuff and made right here in the Houston, Texas, area.

I waited to write this review until after the product was completely installed and I drove over it. I recently purchased a travel trailer that requires me to back over my boulevard to park. I wanted something stable that would not displace and require ongoing maintenance. My steps were as follows...1) Remove sod and top soil at minimum 4 inches below grade. Recommend 6-8 inches if soil is soft. I have hard clay so 4-5 inches was enough for me.2) Layed down woven geotextile fabric. I didn't want to use a basic landscape fabric because it would be destroyed by driving over it within a year. Geotextile fabric is the material that is put under roads to stabilize the soil. Since I have hard clay, soil stability was not a big issue for me but I used it anyway for weed control.3) Layed down 1 inch crushed rock leaving 1.25 inches below grade for the tiles. Very important to not use washed rock or pebbles for this step because washed rock has rounded edges and does not pack/lock together like crushed. I didn't want to rent a plate compactor so I packed the rock using a manual tamper which I already owned (if I had a larger area I definitely would have rented the plate compactor). This left a nice level & soild surface for the tiles.4) Layed down the tiles. I chose to cut my tiles in place. I locked them together, then used an oscillating multi-tool to cut them which worked extremely well and was easy.5) Lastly I used 5/8 inch crushed rock (1/2 - 5/8 inch pieces) over the tiles. I used my tamper again to pack the rocks into the tiles and lock them together.Drove my camper and pickup over the finished product and afterwards you could not even tell my boulevard had been driven on. Truly amazed how well these worked and highly recommend them provided they are installed correctly.
