Liquid
sealant, or "caulk" as it is commonly referred to is the most commonly
used material for the sealing of building components.
It's
performance is often disappointing in joints that move, however, as the
result of it's reliance on ideal installation as well as
adhesion in
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
sealants.
These
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.
The result
is a
hybrid sealant system that exploits the advantages of both
technologies while eliminating their respective shortcomings.

Montana State University's Bobcats stadium is illustrated in the

others who are "thinking outside the bucket" when it comes to joint
sealing.
