In this high traffic mall, the original winged compression seal failed due to unanticipated post tension shortening. It was then subsequently covered over with a rubber-encased coverplate whose expansion anchors had vibrated loose causing a hazard.
Without closing down the deck, by diverting traffic over half of the joint at a time, the failed systems were replaced with the EMSEAL SJS System in under 4 hours. Because SJS installs without the need for embeds, anchors, or any invasive anchoring into the concrete, all concerns about hitting the post tension tendons were eliminated.
The result is a traffic-durable joint system that is watertight–not water managed. Systems that rely on looped gutters under coverplates leave owners with the problem of managing any collected water into drains or elsewhere.
