The Iowa Method for bridge deck overlays has been very successful in Iowa since its adoption in the 1970s.


This method involves removal of deteriorated portions of a bridge deck followed by placement of a layer of dense (Type O) Portland Cement Concrete (PCC).

The challenge encountered with this type of bridge deck overlay is that the PCC must be mixed on-site, brought to the placement area and placed with specialized equipment.


In the sixties, Christensen Brothers, Inc. became involved with a new process developed by the Iowa DOT called High Density Low Slump Bridge Overlay. This relationship has given our company 50 years of experience in this type of Bridge repair and Bridge Deck Replacement.
