Continuity of Seal

In building expansion joints, continuity of seal is the assurance of watertightness throughout its length and through all changes in plane, direction, and intersection within a single joint sealing technology or between one or more technology types. Continuity of seal in most applications is best achieved through the specification, manufacture, and installation of factory-fabricated expansion joint transitions.

Continuity of seal through curb, sidewalk and between dissimilar materials at wall

The above image is a great example of what we mean by “continuity of seal” in expansion joints.
In this condition a Thermaflex parking deck expansion joint crosses a drive lane, transitions up and over a curb, tees into the perpendicular deck-to-wall joint using our “Shear Pocket” technology, and intersects at an offset wall joint sealed with Seismic Colorseal that nests into a “boot termination” that protrudes into the wall and is welded into the Thermaflex system.

Continuity of Seal at Roof to Wall Transitions

This overlooked detail is one of the most critical connections when transitioning building expansion joints. Sika Emseal addresses complex transitions like roof-to-wall intersections with advanced, factory-fabricated solutions designed to maintain a watertight seal through changes in plane and direction. The RoofJoint system, when integrated with Seismic Colorseal and RoofJoint Wall Closures, provides a robust, watertight connection between roof and wall expansion joints. By eliminating reliance on field-applied caulking or patchwork methods, Sika Emseal’s engineered transitions ensure durability, simplify installation, and reduce the risk of leaks, safeguarding the building envelope against environmental conditions.
