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.
The image at left 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 Sesimic Colorseal that nests into a “boot termination” that protrudes into the wall and is welded into the Thermaflex system.
