As an accomplished
inventor Ben Franklin would likely be pleased to know that his
namesake stadium is no longer leaking or employing material
solutions not suited to the challenges of structural joint sealing.
UPenn's Franklin Field
is home to Quakers sports and, since its construction in 1922, has
been a pioneering stadium in many respects. In 1925 when the
second tier of the bowl was added it became the second and largest
two-tiered stadium in the US. The first televised commercial
football game came from Franklin Field in 1939.
What the hallowed
site has shared with many other sports facilities, however, is
leaking expansion joints. The use of field-applied wet sealant
in repeated joint replacements has inevitably met with the same
result--failure in tension or at the bondline
(see photo above left).
The selection of EMSEAL's
DSM SYSTEM for the
expansion joints has ensured that failed-applied caulk and backer
rod approaches are no longer a part of the maintenance demand on the
facility. DSM is one of EMSEAL's line of
hybrid precompressed, preformed joint sealants that offers a durable,
tensionless,
alternative to backer rod and wet sealants.
Unlike wet sealants
in their traditional field-applied format, EMSEAL's precompressed
sealants are never in tension. Tensile stresses at the bond
line AND within the cured wet sealant are the principle reasons for
wet sealant failure. Combine these physical forces with any
deviation from the hour-glass geometry required for wet sealant to
function and caulk-joint failure is likely to occur even after one
winter cycle.

construction or at retrofit--Who else is using EMSEAL stadium joint
