Anchoring your geodesic dome

Smaller geodesic domes do not require massive anchoring; many will use long ground screws or rebar bent in the shape of a “U”. But for a more solid, safe and permanent solution, concrete is poured to create piers. Many also use them as a base and frame for a riser wall.

as a rule for large permanent structures piers should go past the frost line and down to the bedrock.

Rebar should be included to strengthen any pier.
