Expansion Joints for Plaza Decks | Sika Emseal Watertight Building Enclosure Solutions

Sika Emseal offers a multitude of watertight expansion joint systems to ensure a static tie-in to the waterproofing membrane in split-slabs and plaza deck joints. Thoughtfully designed transitions ensure continuity of the building enclosure - www.emseal.com...
RoofJoint (www.emseal.com...) can be used in split-slab and hardscaped decks when drainage or other construction may be impeded by the expansion joint protruding above the structural deck elevation. In these cases an additional expansion joint seal would be needed at the wearing course. (See SJS, DSM and DSM-DS.) As with roof applications where a fire-rated seal is also required, Emshield DFR can be installed directly below the RoofJoint. When transitioning to a vertical wall expansion joint, Seismic Colorseal can be used.

A seismic plaza deck expansion joint system the SJS-FP System (www.emseal.com...) is designed to provide a watertight, trafficable joint system in wide expansion joints in hardscaped decks of split-slab design. SJS-FP expands the use of the SJS System to waterproofed hardscaped split-slab deck designs through the use of structural-slab mounted retainer legs with integral waterproofing side sheets that integrate with the deck waterproofing membrane.
The retainer legs are available in leg heights that can be matched to the topping slab or wear course thickness. The waterproofing side sheets lock into the top of the retainer legs and are embedded in and encapsulated by the deck waterproofing membrane. The SJS System foam/spline assembly installs between the faces of the retainer legs. The foam/spline assembly is constructed from two precompressed foam sealants pre-assembled in parallel adjacent to a heavy-duty extruded aluminum spline. The spline acts as a receptor for attaching the surface-mounted traffic plates that bear vehicle and other loads.
The result is a system that is watertight and covered with a cover plate that is securely anchored into the wear course.
A plaza-deck to solid-slab or wall expansion joint, DSM-FP is watertight and purpose designed for use in plaza decks particularly where a split-slab meets a solid slab or wall - www.emseal.com...
DSM-FP extends the use of the DSM System to waterproofed split-slab deck designs through combination with our FP (for plaza) mounting rails and side flashing sheets that integrate with the deck waterproofing membrane and contain the wearing course.
The material that bridges and seals between the FP mounting rails is Emseal’s DSM System which is a silicone-and-impregnated-foam hybrid sealant that ensures watertightness, absorbs sound, dampens vibration and offers uncomplicated installation.
In contrast to buried joint systems, Emseal’s FP Systems prevent the buckling of pavers or other hardscaped wear course materials and will not suffer flex-fatigue failure at the waterproofing membrane tie-in.
A plaza deck expansion joint, Migutan FP110 and FP155 (www.emseal.com...) are unique designs incorporating side membrane sheets which integrate with the deck waterproofing system to form a continuous, completely watertight system. For applications, particularly over occupied space, where totally watertight integration of expansion joint and deck membrane is a fundamental requirement. Application examples include hardscaped split-slab construction on plaza (podium) decks, split-slab parking decks, stadium concourses, and anywhere waterproofed split slab construction is specified. For applications with softscaped toppings (green roofs, garden roofs, under landscaping) see RoofJoint - www.emseal.com...
Highly configurable, using factory-fabricated transitions, to a multitude of field conditions, Migutan is the only system of its kind with a 20-year track record and tens of thousands of feet installed and functioning.
