Building Expansion Joints and Sealants

Waterproof, fire rated, trafficable, sound attenuating, insulating, air, wind, seismic, and watertight, building expansion joints and precompressed hybrid sealants. A Sika Company.

Using Revit BIM, CAD and Sika Emseal’s collaborative 3-D expansion joint design methodology taught in our AIA-registered seminars, and regularly broadcast online, or just for your firm, it is now possible for designers and contractors to wrap the entire building envelope, as well as ensure that life-safety is addressed, by specifying and installing expansion joint systems that transition into one another and are warranted for continuity of seal between like or dissimilar technologies as well as at the tie-ins to adjacent waterproofing and roofing membranes.

Sika Sarnafil Roofing Membrane and RoofJoint Expansion Joint Detail from Sika Emseal

Roofing system membranes and the expansion joint systems that bridge the gap in the structure are under constant exposure to the exterior elements. The ability to seal these joints and maintain continuity of seal from the expansion joint to the roofing membrane is crucial. Sika Sarnafil and Emseal have now partnered together to offer a Single Source, Full System Warranty for up to 20 years.

Airport Concourse Floor Expansion Joint Cover at BNA Nashville International Airport by Sika Emseal

This case study focuses on the interior floor and wall expansion joint covers at Nashville International Airport. Recently, a retrofit of the concourse floor joints received a custom inverted SJS Seismic Joint Coverplate. The flush installed joint creates a smooth transition for the high-traffic and high-point loads of this airport concourse.

Expansion Joints and Sealants Critical to Building Enclosure Performance

Expansion joints in concrete, steel, masonry, timber and other structures are a critical element in overall building enclosure performance. This is because expansion or movement joints bisect the entire structure. This means that structural as well as building enclosure materials specified to waterproof, roof, clad, and cover the structure are divided by the intersecting opening that is the expansion joint. Consequently, expansion joint openings must be filled, sealed, and/or covered with materials that restore the function of the materials bisected.

Sika Emseal has used as the inspiration for invention of its building expansion joint product line, the performance requirements of the adjacent building envelope materials. This means that in walls, our precompressed foam sealants were developed to perform to, or exceed, the performance test requirements of curtainwall systems. For roofs, our materials incorporate redundancy across the joint gap, at the roof membrane integration, and even in the anchoring method—by ensuring the roof expansion joint is both welded or adhered and mechanically fastened. For seismic expansion joints, our system innovation was built on principles that ensure watertightness at the deck surface, non-invasive anchoring to the joint substrate, and non-invasive anchoring of the expansion joint covers. In parking garage and stadium expansion joint applications, our systems ensure watertightness throughout curb to sidewalk or tread-and-riser steps as well as in transition to concourses and walls–while ensuring a complete offering to handle a wide variety of traffic (cars, carts, people). When it comes to filling joint openings where acoustic requirements are expected, our solution incorporates mass-loading, absorptive and reflective attributes. And our all-in-one water, acoustic, and fire-rated expansion joints were invented and proved to perform to the strictest fire resistance test methods for fire barriers—UL, ASTM, CE, EN, AS, BS, RWS.

Watertightness at the deck surface while ensuring continuity of seal at curbs and parapets is the critical differentiator in our bridge expansion joint. Protecting the piers and beams of the underlying structure is essential to bridge preservation.

Our sealant tapes are more robust than your average weather stripping–incorporating hydrophobic chemistry into a foam matrix that ensures durability and sealing while resisting compression set in a way not possible with traditional closed-cell gaskets.

Perhaps most critically, expansion joints will leak if they are not properly transitioned—between similar and dissimilar expansion joint systems at changes in plane and direction—as well as at the tie-ins to waterproofing and roofing membranes and at wall air-barriers and coatings. As a member of the Sika global family, Sika Emseal is now able to offer complete building enclosure and roof solutions that feature single-source expansion joint warranties between its roof expansion joint (RoofJoint) and best-in-class roof membrane (Sika Sarnafil), monolithic membranes (Hydrotech MM6125) and Sika liquid applied membranes (Sika LAM).

Purpose-designed products are essential in ensuring the durable treatment of expansion joints while ensuring continuity of seal between systems and adjacent materials.
