EXPANSION JOINT
SLAB/HORIZONTAL
Backerseal
™
(Greyflex
™
)
Uses: Walls, Doors, Windows, Panels, Control Joints, etc.
An economical, high performance expanding foam secondary sealant to field-applied liquid
sealant. It is ideally suited to EIFS, as well as concrete, brick, stone etc. Consists of acrylic-
impregnated open-cell foam material combined with laminations of closed-cell EVA foam
in sizes over
⅜
". Non-staining and compatible with a wide range of liquid sealants. Puncture
or failure of primary liquid sealant does not affect sealant system performance. It is supplied
pre-compressed to smaller than joint size with a mounting adhesive on one face. Material is
inserted into 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. R-value of 3.28/inch of depth
adds thermal insulation to joint gaps. Standard sizes from
⅛
" to 10". Movement capability is
+25% (50% total) of nominal material size.
Seismic Colorseal
™
Uses: High-movement Curtainwall, New-To-Existing, Skywalks, Seismic, Masonry, Metal Panels, etc.
Ideally suited to EIFS, curtainwall and metal cladding systems, as well as concrete, brick and
stone. It combines factory-applied and cured silicone facing with permanently elastic acrylic-
impregnated open-cell foam sealant backing. Back pressure maintains seal and ensures that
silicone is virtually never under tension. Supplied in shrink wrapped lengths (sticks). Pre-compressed
to smaller than joint size with a mounting adhesive on one face, material is inserted into joint
and adhered to one side. It then expands to seal the joint. Addition in the field of a silicone
corner bead ensures sealing between the silicone facing and substrate. Non-invasive anchoring,
eliminates drilling into substrates typical of strip-seal systems. Easily installed into inside-corner
conditions impossible to seal with rubber-and-rail type strip-seal systems. R-value of 3.28/inch of
depth adds thermal insulation to joint gaps. Standard sizes from
⅜
" to 10". Sizes up to
¾
" have
single convex facing. Movement capability is +50%, -50% (100% total) of nominal material size.
Available in 11 standard colors.
Precast White, Natural Stone, Gray, Black, Bronze, Sandstone
Adobe Tan, Dusty Rose, Rustic Brick, Blue Spruce, Charcoal.
20H System
™
Uses: Intermediate level decks, joints, perimeter joints, sidewalks, aprons, joints at utility rooms,
parapets, below-grade foundation wall joints, icefloors, etc.
The 20H System
™
is an economical, resilient, and traffic-durable seal. It consists of 20H foam,
epoxy adhesive& topcoat. Permanently elastic, high density, open-cell polyurethane foam,
impregnated with water-based, polymer-modified asphalt, compressed to approximately
20% of its uncompressed dimension. Supplied pre-compressed to smaller than mean joint size,
installed flush with or near to surface into wet epoxy adhesive, the material expands to seal
the joint. Exposed top surface is treated with Topcoat flexible coating to enhace sealing and
durability. Movement capability is +25%, -25% (50% total) nominal material size. Standard sizes
from 1/2" to 4".
DSH System
™
Uses: Traffic-durable seal for a variety of deck and slab applications.
Permanently elastic, high density, open-cell polyurethane foam, impregnated with water-based,
polymer-modified asphalt, compressed to approximately 20% of its uncompressed dimension.
The high-density foam backing is coated with a factory-applied, controlled, and cured coating
of traffic-grade silicone. The silicone provides weathering, waterproofing, and fuel resistance as
well as aesthetic and movement advantages over the precursor, 20H. System consists of DSH
foam, epoxy adhesive and liquid silicone for corner beads. Supplied pre-compressed to smaller
than mean joint size; installed near to surface into wet epoxy adhesive. Standard sizes from 1/2"
to 6". Movement capability is +25%, -25% (50% total) nominal meterial size.
