Hello, Webb’s Water Gardens! This is Steve and Brian from Aquatic Effects. We want to show you another tip about setting and stacking rocks.
Today, we’re using West Virginia Mountain Boulder, which as you can see, isn’t cut. It has sharp edges and is a naturally harvested stone. One of the first things that you want to keep in mind is, when you go to place it down, building against your wall, you want to set your rocks and make sure your first base is nice and tight and level. As you can see, there’s very little movement. As you go to build up, you’re going to want to set your next rock, much like laying brick, where you cap your two bottom rocks by putting the stone on top, up against the wall. When you set the rest of them, you’ll want to make sure everything feels fairly tight. This technique should lock the rocks in place.
Once you’re done if you choose to use mortar, you can lift your rocks up and apply your mortar, or inject your urethane foam. Whatever the case, you want your rocks to sit on their own, as tight as possible. if the rock doesn’t want to sit on its own already, no matter what you put on there, it’s always gonna be subject to movement. The best thing is to do is to get them to sit tight on their own, then apply the adhesive. Once this is in place, you can put your capstone on top to complete the process.
