TRUEGRID | PRO 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)

Absolutely love this product. I ordered 3 boxes of these 2 years ago waiting to get this project done but finally got around to it after the boxes were collecting dust in the garage. They are very solid and easy to install. I found them a breeze to cut through with a sawzall. They were easy to interlock and I really appreciate the flex. I have a high traffic area I was going to put 1/2” crushed gravel in and wanted the extra stability and not have to take gravel all the time. These absolutely keep the gravel in place and give a really solid feeling underfoot. I put a little extra gravel on the top as to not see the grid and it looks great. I didn’t try too hard to level/grade prior and it’s been working out great. The hardest part was moving the gravel. In the future I’ll never lay gravel without this.

I figured out how to make the path curve AFTER putting the first 35 feet down. At first I offset them, and that looks GREAT, but it also makes for a more narrow path.... I made a pathway through my woods just one tile wide, and that's not a lot. Major paths should be 2 squares wide with smaller paths one tile wide. Oh well, looks great. Water flows over and through the gravel, and I'm not dealing with mud anymore, which was the purpose of this project. Once I layed the next 4 boxes, I figured out the S pieces in the tiles allow for curving the path. You need to put a tile down, lock in place, put gravel down on the last tile, then push the tile into position, and place a big rock to KEEP the tile in place... dump gravel, and keep moving. Make sure you don't put too much gravel down at first. You want the grid to hold the gravel in place, so water and blowers don't move it around. If you need to move the tiles AFTER you put down gravel, there's no good way to DO that IF you have to lift a tile to get the last tile UP, so 90% research, and 10% execution. Plan this out. Order what you need. A ton of gravel covers about 200sq ft at 1 inch depth. Make sure you have the gravel dumped in a place that's convenient to your project and not in the way.. I put a tarp down first, and that was a good choice. Crushed river rock looks great for my purposes. I put medium, large, and small rocks on either side of the trail.... thicker on one side, then the other to enhance the appearance of a meandering trail... just lovely! This product isn't cheap, but it's forever, and it's solid. No more time and money wasted on pine straw. I also down a path on my somewhat steep hill. It's in the rock garden, and matches the stones perfectly. I have a flat surface to walk, roll a wheelbarrow, etc. It was a 2 day job.... one day to put down the grid. A day to fill with gravel, and place rocks back.

Awesome product. I have used these to create a patio-like seating/grilling area in my back yard, a handicap accessible walkway from the front of the house to the back Truegrid patio, and as base pads for 3 RVs (under tires and under jacks). They look good, especially with your favorite color of gravel in them, and they hold up very well. Expect weed growth eventually (even with weed cloth or cardboard underneath), and consider using "gravel glue" if you add gravel to prevent it from getting into the cleats of your shoes. All in all, this is an amazing product!

I used these for a small driveway/patio access area that needed to be fully permeable to surface water. Installation was completed by excavating into the rocky/gravely clay subsoil, leveling the area was a challenge but provided an excellent base for woven geotechnical fabric and paver installation. The TrueGrid units installed easily by using a table saw to rip down grids to the correct dimensions and click together in place. Steel landscaping staples were applied on the crossbar cells, then over filled with 3/4" crushed gravel, raked to level surface and compacted. This creates a very stable surface for rolling tires: bikes, cars and trucks. As we progressed into our project I used a skid-steer loader to distribute gravel and topsoil. This was fine for straight travel over the new sections of TrueGrid/gravel, turning a skid-steer on this surface was too much lateral torque and the grids were ripped up underneath, torn and fully exposed. A skid-steer moves by turning the right and left wheels in unison, independently or in opposite directions simultaneously. This was along the edge of the installation, where they were unsupported by neighboring grids, along an interface with concrete slab. In fairness, the same maneuver in loose gravel would have displaced a lot of rock. When the grids are displaced gravel immediately gets underneath and creates a raised section that only exacerbates the problem. It quickly becomes an unstable slip plane extending like a blister under the grids. With continued use the affected grids are completely torn out of the installation (see reference photo where I have removed some of the surrounding gravel to expose the affected grids.. While it was only 2 sections of grid that were displaced, the repair work to restore a level surface was not easy. Fortunately I had a few leftover grids from the original installation. I found it was easiest to cut out the interlocking tabs with an oscillating saw, then remove the damaged sections. The gravel must be completely excavated from the affected grid area in order to repeat the installation process. If I had to do it again, I would use an empty shop vac to clear the gravel. It took me about 2 hours to remove and fully reinstall two grid sections. Note to buyer: load ratings are apparently only for typical unidirectional-drive rolling vehicles, this product did not hold up under significant lateral/twisting loads. For the time and money, this product improves a permeable gravel surface application giving greater stability and expectation for longer gravel retention if installed with fabric underlayment. This is ideal for applications where improving groundwater replenishment and reduction of stormwater runoff is desired, or to establish a quick and reasonably stable ground surface. If it is displaced, expect a long and challenging process to repair, unlike a traditional gravel roadbed—you can't just rake it out level again.
