Lightweight Forms for Bridge Construction

Large precut blocks of EPS15 Geofoam were used as lightweight forms for this bridge project in Camden, NJ. Using a system patented by Universal Foam Products for adhering plywood to EPS, the contractor was able to screw 3/4″ plywood to 2×4’s inserted in precut slots in the EPS blocks. After the concrete was installed the EPS and plywood forms were removed. EPS is much lighter than steel or fabricated wood forms for this type of application, making it easier to work with. It has multiple applications in bridge construction including form liners for bridge columns and horizontal bridge supports, bridge window block-outs, flute fillers for metal bridge decking and internal void fill for large vertical and horizontal concrete structures.
