Expansion Joints and Pre-Compressed Sealants
Replacing Failed Caulk Joints in Precast

sealant, or "caulk" as it is commonly referred to is the most commonly
used material for the sealing of building components.
performance is often disappointing in joints that move, however, as the
result of it's reliance on ideal installation as well as
tension. Tensile stresses at the bond line and within the
cured sealant usually result in adhesive or cohesive failure or both.
It is not
surprising that facility owners and managers are looking for a more
durable alternative. They have found it in EMSEAL precompressed, hybrid
products take the best characteristics of one of the best liquid
sealants (silicone), and combine it with the best characteristics of the
best precompressed, impregnated foam sealant on the market.
hybrid sealant system that exploits the advantages of both
technologies while eliminating their respective shortcomings.
DSM SYSTEM to replace failed caulk joints in the precast bowl of
Montana State University's Bobcats stadium is illustrated in the
Supplied, precompressed to
smaller than the field-measured joint sizes, the
SYSTEM is installed into epoxy-primed joint faces. A sealant
band of silicone is injected between the substrate and the factory-cured
bellows and is tooled into a corner bead.
Joints small and large,
regular and varying, are easily accommodated with size switching.
Inside and outside corners
are handled in the field using prescribed methods or can be addressed
using factory-fabricated customer or
Universal-90 transitions pieces.
The result is
seal from field to parapet using material that is weather, UV, and
traffic durable. And, unlike liquid sealants, or caulk, is
virtually free of the tensile stresses that shorten life span.
sealants are the standard for durability in large and small, wall and
deck, watertight joint sealing.
wax-saturated, precompressed alternatives do not come close in
performance and come with major risks of bleeding and staining.
Revenue loss in affected
concession areas, damage to equipment in storage rooms, disgruntled
athletes and fans are all consequences of leaks at expansion
joints. Energy loss, structural deterioration, and costly repairs
are all the result of
short-term thinking in expansion joint selection.
Elimination of these
problems in new sports venue construction as well as in retrofit of
existing structures is a central focus of EMSEAL's.
The approach is grounded
in a collaborative process centered on joint treatment that requires all
of these parties to
detail, specify, construct, fabricate, and install
