The EMSEAL Approach to
Successful Expansion Joint Treatment--Collaborative,
Detailing, Construction, Fabrication, Installation.
It’s not just about great
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
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
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 detail,
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
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
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
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.
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, A/E’s,
general contactors, EMSEAL, and a select group of like-minded
waterproofing sub-contractors are proving this approach possible and
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.

Sealant and Expansion Joint Leader Continues Stable Growth Trajectory
WESTBOROUGH, MA—A manufacturer of
precompressed sealants and expansion joint
systems for the commercial construction industry as well as for numerous
gasketing applications in industrial other specialty market applications,
EMSEAL has operated out of locations in the Northeast United States of America
the Greater Toronto Area in Canada for nearly thirty years.
The company’s long history of quality
in product, creativity in problem solving, curiosity in innovation, and
personalized customer service are the basis of EMSEAL's stability and commitment to focus. This strong
foundation supports the market-driven innovation, decision-making and rapid
customer response that characterizes the company.
Established in 1949 by the
late Mr. Max Baerveldt, as Electro Mechanical Construction
(Pty) Ltd., the company was one of the first licensees of a sealant
technology invented by Laban Mast in the Netherlands in the late 1950's.
The sealant product, called EMSEAL
became the basis, as well as the corporate name, of the present
company, which has operated in North America since 1979.
over the years is based on management according to a carefully developed strategic plan
under the leadership of a committed and focused executive, sales,
engineering, manufacturing and customer service team.
“EMSEAL has solidified its place as a leader in the sealant
and building expansion joint marketplace,” comments CEO, Lester
ongoing success is a tribute to everyone who works with EMSEAL, from the extraordinary service provided by our in-house sales and
specification development engineers, to manufacturing, outside sales,
field technical service and administrative staff, as well as through our
independent reps, the EMSEAL team delivers quality based on the principles
of market-driven, performance-proven products and services and
professional, customer-centered service”.
Movement Joint Gaps are Problematic:
Our experience, validated by the research of CIRIA (Construction Industry
Research and Information Association), is that the treatment of movement
joint gaps in buildings, from design, technology and installation
standpoints, are grossly under-emphasized: "Although they are a minor
component of the building envelope, joints with sealants are often
responsible for defects and failures-sometimes after only a couple of
Expansion joints constitute
a small percentage of a construction budget yet, along with other
waterproofing-related issues, are responsible for the majority of all
post-construction complaints and call-backs.
Our closely held company
is committed solely to providing lasting joint-sealing and bridging
solutions. We are not distracted by involvement in the offering of other
types of products--patching materials, deck coatings, etc.
Results of a New Paradigm: Our
single-minded pursuit of new ways of looking at our services and products,
has resulted in the supply of millions of feet of sealant materials. Over
the last twenty years, for example, more than 1,000,000 LF of parking deck
expansion joint material have been installed on projects ranging from
small and medium retrofits, to large new construction projects. Through this
process we have cultivated relationships with well-respected, regional, national and
international design firms, engineering firms, contractors, and owners.
Pre-Installation Quality Assurance:
We have developed expansion-joint checklists, and a schematic layout
system for use by designers, reps, contractors, and ourselves in
communicating expansion joint needs. This system has dramatically improved
the quality of information we receive and provided a sound basis on which
decisions about choice of product can be made. Additionally, the use of
this system has considerably reduced the amount of time all parties spend
communicating their needs. Finally, it has provided a means by which
costly errors can be avoided during design, fabrication in our factory,
Attention to Detail: We have
developed and are aggressively promoting the full potential of heat
welding our Santoprene seals to provide watertight transitions and
terminations in the most difficult situations. We are not satisfied with
simply supplying material to meet the requirements of cross-section design
and we encourage axonometric detailing of these conditions.
Our details for sealing
terminations include watertight transitions from joints in decks to
vertical structures. We have in the past six years supplied over many
thousands of factory welded Santoprene direction changes and terminations.
Installation Quality Assurance: We
have instituted material delivery programs that provide contractors with
mixing equipment including all accessories as well as, procedures, and
training to aid and simplify the installation of our products.
Credibility: Respect and credibility
are earned. The list of projects on which we have earned our reputation
and the trust of much of our industry is extensive and can be reviewed at
our project references page
and in our case studies.
completed and ongoing projects include the resealing of the Empire State
Building, stadium installations at the new New York Yankees, new New
York Mets, Indianapolis Colts, and retrofits at Houston Astros, Tampa
Bay Buccaneers, Lambeau Field, and Gillette stadium.
We have, at the
invitation of many of the nations top design and engineering firms, as
well as at the Sealant Waterproofing and Restoration Institute (SWRI) and
numerous state chapters of the International Concrete Repair Institute
(ICRI), presented very well-received seminars on the treatment of
