Is there a particular way that gluing or pegging LR together that works better then the other. I am going to add more LR and i want to have my homework done on ways to keep stacked LR together and in place.
I know you can also use acrylic tie's from Home Depot or wherever. My rocks are just on top of each other so I can't help you with the gluing or pegging.
If you want something really cool looking. You can figure out the shape of the piles that you want. Get a masonry drill bit and drill the hole to make a pvc structure to hold it in place. Then you can get puddy to fill in the spots that you see pvc. You can also ziptie small pieces in place.
