As you can see here, the legs that will carry the domes must be cut vertically in half.
After the domes are placed in cascades, the arches under the domes must be closed. As you can see in the photo below, we used 10 mm OSB in this application and screwed the OSBs into the domes. If wooden material is not desired to remain in the concrete, 10 mm plastic plywood can also be used. Before placing the OSBs, the edges of the domes that the OSB will rest on must also be cut. Also, the use of screws is a must in this application.
