On June 25, the first opening day in Brooklyn in 44 years, the "Cyclones" took to the field of their new ballpark.

The team was named for a Coney Island rollercoaster and while the views from the stadium are spectacular, designers made sure that the expansion joints presented no hair-raising surprises.

Keyspan Park features technologies from a range of options to suit joint conditions while ensuring continuity of seal in changes in plane and direction as well as between technologies.

Starting in the exterior walls of the superstructure, structural expansion joints are sealed with SEISMIC COLORSEAL.  This products unique, non-invasive anchoring ensures the substrates are not violated with screws and anchors.  In addition, SEISMIC COLORSEAL can be transitioned around, through, over and under building elements to ensure continuity of seal and thermal insulation.

Blockouts required for EMSEAL's THERMAFLEX system in the bowl are continued 8-inches (200mm) up the inside of the parapet wall.  This allows the SEISMIC COLORSEAL to be married into the THERMAFLEX to ensure continuity of seal.

Each join is welded throughout the extrusion's cross-section to ensure that the primary and secondary seals inherent in the system are watertight.

As a further quality measure, each weld is wrapped with a fully-welded reinforcing sheet that is blended into the main seal for aesthetics.

Ensuring watertightness in split-slab decks is particular specialty of MIGUTAN from EMSEAL.

This system features side flashing sheets which are embedded in and encapsulated by the hot-rubberized asphalt waterproofing membrane on the structural deck.  The legs of the MIGUTAN are selected in a height to suit the concrete topping thickness. 

EMSEAL's approach to stadium expansion joint sealing centers around the belief that through better design, better products, and better installation we can provide owners with  trouble-free expansion joint systems.  Keyspan Park is validation of this approach.
