The EMSEAL Approach to
Successful Expansion Joint Treatment--Collaborative, 3-D Design, Detailing,
Construction, Fabrication, Installation
It's not
just about products.
While
EMSEAL prides itself on having high-quality, innovative and durable
materials for use in sealing and bridging small and large, building
component and structural expansion joints in foundations, decks, walls,
and floors, the company's track record of successfully completed projects
is equally attributable to its approach to expansion joint treatment:
Anybody
can make an expansion joint appear watertight in cross-section.
However, joints leak at changes in plane, direction and where dissimilar
joint materials meet.
Successful projects with expansion joints that don't leak are
characterized by a collaborative commitment by the A/E team, the general
contractor, the joint manufacturer, and the waterproofing sub-contractor
to think, design, detail, specify, construct, fabricate, and install
three-dimensional solutions.
The
process begins at design with the visualization by the A/E team and the
joint manufacturer of expansion joint locations, layout and impact on all
other adjacent materials and spaces.
This
visualization is aided by the use of simple isometric line sketches of
joint layouts which reveal conditions that could be designed-out,
simplified, or for which details must be developed. The A/E then
supplements the usual cross-sections with axonometric details of
conditions involving changes in plane, direction and between dissimilar
materials.
To
these conditions, the expansion joint manufacturer must furnish
axonometric CAD details
showing their materials adaptation to these conditions. The
manufacturer's application of their material to the designed conditions
should be warrantable as watertight at all agreed upon changes in plane,
direction, and intersection between various joint materials. The
final isometric layout(s) and all cross-section and axonometric details
then become part of the bid documents and working drawings.
Before and during construction the
general contractors' role
is to elevate the place the expansion joints typically occupy in the
sequencing path. ALL trades must be held accountable for their work
in relation to expansion joints. The joints, for example, must be
protected from construction traffic damage and cannot become a place to
accumulate construction tolerances.
The
expansion joint subcontractor must commit to taking field measurements
from which the manufacturer can fabricate and furnish factory-welded,
warranted assemblies to install into the relevant joint locations.
This collaborative approach is not just theory. It is a practice
that has resulted in the successful execution of watertight expansion
joints on new and retrofit projects on structures of every type.
From the National Naval Medical Center in Bethesda, to the enormous, newly
constructed mixed-use development
Atlantic Station in Atlanta, to the
retrofit of
FedEx Field Washington Redskins Stadium,
and the newly constructed
Citizens Bank Philadelphia Phillies Ballpark,
owners, general contactors, EMSEAL, and a select group of like-minded
waterproofing sub-contractors are proving this approach possible and
practical.
If this
collaborative and disciplined approach is not adopted as the basic
philosophy on any project of any scope, whether a stadium, hospital,
school, government building or airport, it can be expected that leaks at
expansion joints will constitute a high percentage of post tenancy
headaches.

The EMSEAL Approach to Gasket, and
Sealant Solutions:
For more than 30
years, EMSEAL materials have and used in
gasket and OEM sealing applications. EMSEAL's preformed, precompressed
sealant tapes as well as sheets, rolls, pads, and master rolls have be supplied
to OEM's and converters worldwide.
Applications include, automobile, marine, log
home, recreational vehicle, awning, telecommunication shelters, HVAC, building systems, awnings,
precast concrete building systems, precast walls, precast foundations, windows,
metal roof and building systems, retrofit roof drains, and many
more.
The Specialty Market Division of EMSEAL was
expanded in 1995 to incorporate product application specialists devoted
specifically to assisting OEM's in selecting sealants to suit their component
sealing needs.
Grounded in the latest innovations in
impregnated foam sealant technology, EMSEAL sealant tapes deliver extraordinary
value through durability and performance.
EMSEAL sealant tapes are a unique hybrid of the
best features of liquid-adhesive sealants infused into a cellular foam matrix
that provides resilience, compression recovery and unmatched durability.
EMSEAL sealant tapes compress into their own matrix and do not extrude, squeeze
out, or spill over like liquid or butyl sealants. This extraordinary
combination of features results in a material of significant versatility,
aesthetic advantage and suitability to a wide range of uses.
