MCU Park features technologies from a
range of options to suit joint conditions while ensuring
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,
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
joints in the exterior transition over and down parapets to meet the
tread-and-riser joints of the bowl, watertightness is critical.
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.

As a further quality measure, each weld

EMSEAL's integrated 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.
