At World of Concrete 2015, SSI announced the new Silspec SES Expansion Joint System. The new joint system is comprised of SSI’s proven Polymer Concrete Header materials, Silspec 900PNS and Silspec 2000, combined with the Silspec SES Seal. The system is easily adapted to use in either new construction or the repair of damaged expansion joints on bridges or other elevated structures.
Joint failure is frequently the result of not matching the movement capability of the expansion joint to the movement expectations of the structure as a product of its length and temperature rangefor its geographical location. Recalculating these factors may be necessary to ensure the correct size is used on the retro-fit.
Traffic, freeze-thaw and rebar corrosion can crack or deteriorate concrete or asphalt at joint edges. By removing the failed concrete or asphalt and replacing it with a Silspec Polymer Concrete the joint edge will be repaired and reformed to accept the Silspec SES Seal.
The SES Seal is a pre-compressed silicone and foam hybrid that is installed into field-applied epoxy adhesive on the joint faces. The joint seal can be installed in Silspec Polymer Concrete Nosings, concrete or steel.
The system provides a water-tight seal that is easily installed across the deck in lane-to-lane construction methods. It does not require embedded pins, anchors or rails for installation.
Along with a wide range of joint opening sizes, the Silspec SES Seal can be step-sized to accomodate variations in the expansion joint opening. This ability along with the available factory pre-made Universal 90-degree transions and terminations makes Silspec SES a remarkably installer-friendly system.
