Blocking traffic noise from the I-279 Veteran’s Bridge which is just above the building required a seven-layer application of Modified Bitumen from Siplast, Polyethylene, three layers of extruded Polystyrene insulation, a Polyester protective layer, and a top application of loose aggregate. A 2-inch concrete pad was installed under the bridge to protect the roof from thrown or dropped objects. Owned and managed by the Buncher Company.
