Emseal Horizontal Colorseal

Horizontal Colorseal

HORIZONTAL COLORSEAL is ideally suited for ensuring watertightness in horizontal-plane structural, seismic, and abutment joints in non-trafficked decks of cast-in-place, precast or post-tensioned concrete.

HORIZONTAL COLORSEAL is among EMSEAL'S family of industry-standard setting pre-compressed hybrid sealant technologies. HORIZONTAL COLORSEAL combines a factory-applied and cured silicone bellows with an impregnated expanding foam backing and is watertight, odorless, clean handling, UV stable, non-staining, low temperature flexible, high-temperature stable.

HORIZONTAL COLORSEAL features EMSEAL’s unique microsphere-modified acrylic impregnation infused into a cellular foam base material and is coated with a high-grade silicone coating.

  • Watertight
  • Airtight
  • Insulates
  • Sound attenuating
  • Thermally insulating
  • High-movement, tensionless silicone bellows
  • Rapid installation - new or retrofit
  • Non-invasive anchoring
  • Aesthetically and practically versatile
  • Easily handles changes in plane and direction
  • Easily handles curved expansion joints
  • 100% free of wax compounds
  • Ideal for new installations as well as expansion joint repair and retrofit

Uses: As a watertight seal in joints in protected deck applications beneath cover-plates, or at perimeters in:

  • Decks: structural joints, perimeter joints, isolation joints at stair-towers/elevators
  • Parapets
  • Roofs
  • Concrete covers on above-grade tunnels, waste water tanks etc.
  • Back-up seal beneath expansion joint-cover assemblies
  • Stadiums
  • Arenas

Standard Sizes: 12mm - 250mm
Note: Sizes under 40mm are manufactured with a single bellows and are supplied as 3.05mtr (10') lengths on reels. Larger sizes incorporate multiple bellows and are supplied as 2mtr sticks.
Movement Capability: Total 100% (+/-50%) of nominal supplied size
Colours: 26 Standard colours & custom colours are available (contact Allco to discuss further)

Performance Limitations

  • Substrates must be capable of resisting, without deflection, displacement, or deformation and at least 2.5 pounds of backpressure psi of the HORIZONTAL COLORSEAL material.
  • Metal coverplates (by others) must be installed above HORIZONTAL COLORSEAL where spiked-high-heel pedestrian traffic, or other high-pointload/small-contact-surface area loads are anticipated.
  • If movement exceeds +/-50% (100% total) of joint-gap size at mean temperature, integrity of seal will be affected.
  • Capable of lateral ("shear") movements up to +/-50% (total 100%) of joint size at mean temperature.
  • Standard sizes from 12mm to 250mm. Other sizes available subject to review of application: consult Allco.
  • HORIZONTAL COLORSEAL is used for horizontal, deck applications that are protected from direct contact with traffic; for example, recessed slightly below concrete surface and covered with a metal plate, or located next to a wall or in other locations where no traffic, pedestrian or otherwise, can contact the product.
