Split-Slab Joint Selection Guide


Below is a selection of some of the many projects for which EMSEAL has furnished MIGUTAN watertight structural expansion joints in split slab and plaza deck applications.  EMSEAL is the only manufacturer with 20+ years of track record of watertight split-slab deck expansion joint sealing using this technology.  For a larger image, click the image.  Any questions please contact us.

New York, NY, Jet Blue Terminal, JFK International Airport
There is nothing worse after a long flight and all its hassles than to have to wait for your cab beneath the icy drips of leaks from above.  Departure roadways at airport terminals are roofs.  These roofs are over the arrivals area. These roadways are commonly designed as split-slabs with a buried waterproofing membrane on the structural deck and a topping slab as the wear course.  Expansion joints used to isolate the roadways from the terminal building must be watertight.  In order to be watertight, the joint must integrate into the deck waterproofing membrane.  Only MIGUTAN from EMSEAL was purposely designed to achieve this.  The static integration of the MIGUTAN side flashing sheets into the deck waterproofing membrane ensures watertightness while joint movement is accommodated by the elastomeric insert at the wear course surface.  Following the curve in the deck is no problem either.  Working with EMSEAL's technical staff, the contractor provided field measurements and condition surveys from which EMSEAL produced detailed shop drawings.  The materials were manufactured and marked according to the shop drawings making installation straightforward and efficient.

Boston, MA, 100 Cambridge Street, Mixed Use Office/Residential/Retail
Mixed-Use facilities usually incorporate high-rise office and/or retail structures with parking and open space.  Consequently, open spaces are usually situated on split-slab plaza decks.  MIGUTAN from EMSEAL is the original joint system designed to be integrated into the structural deck waterproofing membrane to ensure watertightness on these critical conditions over occupied spaces.  These images illustrate the integration of the MIGUTAN system into the plaza deck elements. Unlike looped membranes, and other buried "band-aid" approaches, MIGUTAN ensures a static, watertight connection to the waterproofing membrane while accommodating movement at a purpose-designed, maintainable, sealing insert.

Chicago, IL--President's Plaza, Corporate Office
The bolt-down joints in the top of a concrete curb in the asphalt-topped, split-slab roof over parking always leaked.  Bolt-down systems (a DOT bridge joint crossover) are not watertight.  In addition perpendicular cracking in the concrete supporting curbs caused water simply to bypass the joint and the deck waterproofing membrane to leak below.  In the second full replacement retrofit, bolt-downs were specified again.  As an alternative, the watertight MIGUTAN system was proposed.  After complete integration of the MIGUTAN to the hot-rubberized asphalt deck waterproofing and through the use of watertight, factory-fabricated transitions and terminations, the deck is finally watertight.

 
Before: Leaking through failed bolt-down joints is made worse by leaking through cracks in the supporting concrete header. During:  Watertight, factory-fabricated transitions in the EMSEAL MIGUTAN joint system are integrated into the deck waterproofing to create a continuous, waterproof deck system. After: With asphalt overlay and landscaping replaced, the entire deck is watertight.

Itasca, IL--300 Park Boulevard, Corporate Office
The story of 300 North Park is very typical.  An office tower with parking below and elevated driveway up to the main entrance that leaked "since the day it was built".  Topical fixes over years were never effective, making the spaces below untenantable or unusable only after the addition of makeshift gutter systems.  Gutters only conceal the problem however allowing deicing salts to corrode the structural support below.  Eventually, MIGUTAN was specified as a lasting solution. With the various topping finishes removed, the MIGUTAN was installed on the structural slab and tied into the deck waterproofing membrane.  The topping materials were replaced the building at these locations is watertight.

Champaign, IL--University of Illinois, Post-Genomic, Biotech Building
College and University owners live with their structures forever.  Like other building owner/operators, for them the life-cycle cost of an expansion joint material material selection is easy.  Choose the best way to treat expansion joints to ensure watertightness and the long-term investment will pay off.  The real cost of replacing a cheap, buried band-aid, looped membrane system at the structural level is the cost of digging up the plaza.  The up front cost of treating the joint with MIGUTAN will far pale in comparison.

 

Perimeter joints in plaza decks around buildings are notorious for leaks.  In addition, whether at new construction or retrofit, substrate conditions create challenges for proper watertight treatment of the joints.  Addressing substrate conditions to accommodate the attachment of the MIGUTAN system inevitably results in better design for all surrounding building elements--windows, cavity walls, facade panels, etc.

 

Left: Deck-to-wall runs, incorporating columns and other offsets and that eventually transition to deck-to-deck are handled with factory-fabricated, watertight transitions from EMSEAL.

Middle and Right: In straight runs, MIGUTAN integrates with open-joint pavers.  Watertightness is assured while the sealing insert that accommodates structural movement is accessible for long-term maintenance if needed.
