Bricked Furnace Hearths contain multiple joints that can fill with sand, scale or other debris when cold, which then expand when the furnace is operational again.  Poured Furnace Hearths often have different ceramic characteristics throughout due to drying from only one side (the hot face).  Thermal and mechanical abuse will take its toll on all Furnace Hearths, ultimately causing failure. 

Precast Hearths have the benefits of exponentially fewer joints, coupled with a complete and controlled dry out.  The properties of a Precast Furnace Hearth are superior to those either poured or bricked.
