Welcome to the Mid-State division of Filigree Systems, Inc. in Cranbury, New Jersey. The Filigree method is a process for construction of concrete decks that successfully integrates “factory precast” and field-construction technologies. This is accomplished by constructing such decks from two interconnected concrete placements, one made in a factory, and the other done in the field. The Filigree Wideslab method has a 40 year success record as an efficient and economic construction process that results in safe and lasting structures. Filigree construction and design is in full compliance with the former BOCA and current ACI and ICC building codes.
