SEISMIC COLORSEAL is ideally suited for ensuring watertightness in vertical and horizontal structural, seismic, and abutment joints in walls of precast concrete, brick, curtain-wall, stone, etc.

New!  NOW also available--SEISMIC COLORSEAL-DS (Double sided) for shallow-substrate applications.
 

SEISMIC COLORSEAL is the latest in an evolution of precompressed hybrid sealant technology.  Developed by EMSEAL in the early 1980's, precompressed hybrid sealants combine the best of liquid and preformed sealant features while eliminating the shortcomings of each.  SEISMIC COLORSEAL has an unmatched  20+ year track record of  performance.

Evolved from EMSEAL's COLORSEAL, SEISMIC COLORSEAL combines a factory-applied and cured silicone bellows with an impregnated expanding foam backing.  In contrast to COLORSEAL, the backing of SEISMIC COLORSEAL contains less foam, thereby freeing up volume for greater movement without stressing its components. The inherent secondary seal in the foam backing (as in the original COLORSEAL) is traded for the doubling of movement capacity and the silicone bellows does the waterproofing and acts as the weathering surface.
 

SEISMIC COLORSEAL features non-invasive anchoring which means you are not drilling and screwing into sensitive substrates. This eliminates the risk of spalls and enables installation into inside corners that are impossible to seal with screw-anchored strip-seals.

The expanding foam backing is acrylic-impregnated cellular foam combined in some sizes with laminations of closed-cell foam.  The impregnated foam contains no wax or asphalt compounds.

Backpressure from the stored strain energy of the precompressed foam secures the system to the substrate and ensures that the silicone bellows is never under tension from the effects of joint movement.

SEISMIC COLORSEAL has an R-value of approximately 3.28 per inch of depth which imparts thermal insulation at structural joint-gaps where thermal loss through strip-seals is often significant.

Unlike imitations that use closed-cell foam backings and that must be forced into compression in the field, SEISMIC COLORSEAL is supplied pre-compressed to smaller than the joint size.  This means that neither the bellows nor the corner bead, nor the foam backing are in tension either during the full extent of movement capability nor as a result of compression set typical in closed-cell foams.

SEISMIC COLORSEAL has a mounting adhesive on one face.  After removal from its packaging, the material is inserted into the joint and adhered to one side. It then expands to fill the joint. The combination of the active backpressure and the pressure-sensitive nature of the acrylic impregnation ensures the attachment of the foam to the other substrate.

Standard sizes from 3/8" (8mm) to 12" (300mm). 
Sizes up to 3/4" (20 mm) have single convex facing.
Sizes from 1" (25 mm) and bigger have multiple bellows coating.

Available in 12 standard colors. Custom Colors available.
