A very busy city required an emergency replacement of pavement over an existing manhole.  The production crew at Advance Concrete Products Co. poured the precast roof at our plant after precise measurements with the contractor.  The existing pavement was cut out in the morning, the precast concrete heavy duty slab was set in place by the Advance Concrete crane operator, and traffic was flowing in the afternoon.  Save time and money with precast panels from Advance Concrete Products Co.
