Oct 19, 2016 · Grinding Mill FOUNDATION. Adequate foundations for any heavy equipment, and in particular Marcy grinding mills, are extremely important to assure proper operation of that equipment. Any slight settling of foundations will cause bearing and gear misalignment, resulting in excessive wear and higher maintenance costs.

Seismic Retrofitting - Foundation Technology

Seismic Retrofitting is the reinforcement or modification of an existing structure against anticipated seismic activity (an earthquake). It also pertains to the subsequent fallouts of an earthquake such as soil failure or aftershocks. Depending on the structure, residential or commercial, the process of seismic retrofitting can differ a bit.
