MANHOLES AND CATCH BASINS

The strength of precast concrete gradually increases over time.  Other materials can deteriorate, experience creep and stress relaxation, lose strength and/or deflect over time.  The load-carrying capacity of precast concrete is derived from its own structural qualitities and does not rely on the strength or quality of the surrounding backfill materials. –NPCA  Website
