the production of wood pulp and paper products requires extensive concrete structures including foundations, walls, raised platforms and kilns. refractory in kilns needs to be replaced periodically. a variety of maintenance, upgrade, retrofit, and replacement projects in this industry calls into service the full array of demolition equipment: core drills and diamond wire saws for cutting concrete bases, walls and foundations, and for releasing and cutting tanks and chests. robotic hammers are able to work in the limited space of kilns to effectively break refractory and lime buildup for removal.
