On the inner foundation ring there are holders for solid steel brackets, which are provided with holes for ground anchors. If required, long wood screws, threaded rods or steel ground anchors can be connected or screwed to the subsurface via these drilled holes. If ground anchors are used, the steel brackets and ground anchors must be installed before the substructures and floors are fitted. Anchoring the foundation ring provides additional protection against lateral forces and extreme wind loads. Often these anchor points are also used to secure the domes e.g. on floating pontoons, flat roofs, tree houses or similar exposed surfaces. We generally recommend anchoring the foundation rings to the ground to increase safety. If the domes are installed outdoors, this is essential. Details of wind loads and load distribution can be found in the structural analysis documents..
