A seismic anchor has a head for location in a hole in ground-connected structure and a shaft connected thereto to extend out of the hole and mount members or equipment to be isolated from vibrations. The head is surrounded by vibration damping means, such as a high durometer rubber or rubber-like material. A covering extends along the shaft to the damping means. Solidified bonding agent in the hole, above the head and the vibration damping means, secures the anchor in place while the sleeve prevents the bonding agent hardening to the shaft and preventing relative vibration between the ground-connected structure and the shaft.
