Emseal Colorseal-On-A-Reel: Building Joint Sealant

Emseal Colorseal-On-A-Reel is a building joint sealant, Emseal Colorseal-On-A-Reel (COR) is a cost-effective version of EMSEAL’s industry-standard Seismic Colorseal precompressed primary seal shipped on a reel for rapid installation into small joints. It ensures watertightness in vertical or horizontal structural and abutment joints in virtually any substrate. Reel-packaging, in contrast to ‘stick’ packaging:  reduces waste, lowers production costs, makes handling easier, and installation rapid. Colorseal-On-A-Reel is a tensionless solution to small joint sealing and is half the price of similarly sized ‘stick’ Colorseal. Its installed-cost makes COR a cost-effective alternate to ‘caulk and backer rod’. And COR not only seals out water, it seals out air, heat, cold, and sound as well. Questions?Contact Us.

  Emseal Checklist

Colorseal-On-A-Reel replaces traditional liquid sealant and backer rod in the typical “caulk and backer rod” configuration that relies for performance on the difficult-to-achieve ‘hour-glass’ shape. In doing so, COR eliminates the primary reason for sealant joint failure – tension – at the bondline and within the cured liquid sealant. COR installs rapidly and eliminates many of the myriad steps required to achieve a neat, functioning joint seal using liquid sealant and backer rod.  No grinding, priming, backer rod insertion, masking, mixing, or tooling.

  • Tensionless, pre-cured silicone primary seal
  • Cost effective
  • Shipped on 10-foot reels
  • Smooth convex surface
  • Rapid installation–new or retrofit
  • No priming, masking, mixing, tooling or backer rod placing
  • Watertight
  • Airtight
  • Insulates
  • Sound attenuating
  • ABAA Compliant
  • Resists hurricane force wind & water
  • Aesthetically and practically versatile
  • Easily handles changes in plane and direction
  • Conforms to substrate irregularities
  • Easily handles curved joints

Watertight—the tensionless silicone bellows is installed just below the deck surface. This ensures watertightness is achieved at the deck surface.

Non-Invasive Anchoring—there are no hard metal-to-concrete connections in the system. This includes embedded pins, anchors, screws, bolts or tracks, trays or rails. The system is locked to the joint faces by means of the 1) backpressure of the foam, 2) the epoxy adhesive, and 3) the injected silicone sealant band at the joint face to foam and silicone bellows interface.

Continuity of Seal—as in all EMSEAL expansion joint systems, continuity of seal through changes in plane and direction is an essential performance differentiator. Details for watertight, field-fabricated transitions from deck to wall, at curbs, sidewalks, parapets, tees, and crosses are available with the DSM SYSTEM.

Aesthetics & Versatility—Standard color is gray (other colors available), uniform bellows appearance, double sealing, fuel resistance, and an enhanced ability to handle variations in joint size are among other system features.
