economical, high-performance seal for above-grade wall joints in
concrete, brick, stone, etc. where black reveal or shadow-line effect is
desired or in concealed conditions.
Permanently elastic, high-density,
open-cell polyurethane foam, impregnated with water-based,
polymer-modified asphalt, compressed to approximately 25% of its uncompressed dimension.
Supplied pre-compressed to smaller than
joint size with additional self-adhesive on one face to aid
installation, Material is inserted into the joint and adhered to one side. It then expands
to seal the joint.
Sealing between the foam and substrate is
achieved through a combination of the pressure-sensitive adhesive
impregnation and the back pressure of the expanding foam.
Material is installed flush or near to the
surface as a primary seal.
Standard sizes from 1/4" (6mm) to
4" (100 mm)
Movement capability is +25%, -25% (50%
total) of nominal material size.
Joints in below-grade foundation walls
utilize the higher-density 20H System.
