Data center expansion joints are a critical part of data center construction. Data centers demand uncompromising performance from every component of their building envelope.
At Sika Emseal, our expansion joint systems are engineered to meet these rigorous requirements, ensuring watertightness, fire resistance, and long-term durability. Our solutions have been integral to numerous data center projects across the country where products like Seismic Colorseal®, RoofJoint, and Emshield® WFR2 were employed to provide comprehensive protection across various structural joints.

Roof-to-wall expansion joint interface addressed using RoofJoint and RoofJoint Closure to transition to Seismic Colorseal in the wall. This assembly from Sika Emseal ensures a watertight expansion joint transition key to a high performance, data center building envelope. Redundant sealing across the joint opening, at roof-to-membrane integration, and redundancy of attachment method (welded + mechanically fastened) uniquely ensures proper and positive integration with the roof membrane. When specified in conjunction with Sika Sarnafil, the joint to roof membrane is available with a single-source warranty ensuring owner/operator peace of mind.
The often overlooked interface between the roof and wall at expansion joints is uniquely addressed using Sika Emseal’s RoofJoint and RoofJoint Closure. This expansion joint transition is essential to ensuring a high-performance building enclosure.
