Ekodome anchor plates are designed to be mounted on each of the geodome's bottom hubs and fastened to the foundation.
We recommend purchasing the Ekodome anchor kit if you're building a permanent structure with your geodesic dome kit, for example, a geodesic dome house or greenhouse home.
The anchor plates will be mounted on the Ekodome's bottom hubs. These anchors allow the dome to be fastened to a foundation. The geodome can be secured using lag bolts for wood or concrete anchors for a slab.
If you use raw land as your foundation, the anchors will provide a hole to use creatively with whatever ground anchor solution you choose.
