I have used these for several years now, and they work well. I had to move one of the beds (bizzy brain made a change in a design), and breaking them apart was tough, but worked by fulcruming them with another pager. They are put in one by one, leveled, and then glued to its neighbor. Makes eight-inch deep beds, and no wood rot.

My dry climate here means I do have to water often. I do have frosts, but no heaving of the ground.

If you have a veggie or any garden where you don'y plant , lay them out after leveling , everyplace you plant one you get no weeds. I used to pave my garden with scavanged pavers, plus all around the plot of my property I pulled them for various reasons. I may go back to raised beds this year and then again pave everything that isn't food or grass, (lawn kind,,,, but one day perhaps). Then I can garden easier and no/less weeds.

Coroplast become available after election season. As politico's do NOT return and remove their signage. I used it for underlayment of rock beds, a walkway. I showed a friend how to use in his garden he thanked me a lot. He had almost no weeds. I got him to seal the edges with silicone then gorilla glue them like a giant auto sunscreen, then chop out circles for plants. Extra hole were added all over, but each had the most expensive weed barrier glued over on both sides. He was amazed how it worked for him. He layed pavers down the walking areasand all around.

I love the glue concept for the blocks but we get freeze thaw and ground heave. I will need to go down 3 1/2-4 feet and lay cinderblock. But the effect is quite nice.
