Self Expanding Cork
Molded of selected cork granules and resin binders then
specifically treated to permit expansion of as much as
50% of original thickness. The material is non-extruding
and used where excessive contraction is anticipated.
Because of its mechanical sealing properties, it
is particularly suited for joints in liquid-containing
structures, (in conjunction with waterstops and/or
sealants) or for preventing intrusion of foreign matter
into overly contracted joints. Elastomeric, chemically-
cured sealants are recommended for use with this
product. Weight at 1/2" thickness is 1.2 lbs per sf.
Conforms to:
ASTM D 1752 Type III
AASHTO M 153 Type III
HHF 341F Type II, Class C
CRDC509 Type III
FAA P610-2.7
Cork
Preformed from selected cork particles and bonded
together with an insoluble resin. This joint filler is resistant
to acids and alkalies, is flexible, waterproof and light in
color. It will not extrude when compressed to 50% of its
original thickness and will recover to approximately 95%
when released. Cork expansion joint is compatible with
elastomeric, chemically cured sealant. Applications
include water and sewage treatment plants, flood walls,
outlet works, spillways and industrial construction. Weight
at 1/2" thickness is .75 lbs per sf.

Sponge Rubber
Neoprene sponge rubber is resilient and compressible.
It will compress without extruding and recover to
90% of its original thickness. It is compatible with
all chemically-cured elastomeric sealants and
can be used as an alternate to cork (meets all test
requirements). Ideal for use in water and sewage
treatment plants, flood walls, outlet works, spillways,
bridges, commercial and industrial construction.
Weight at 1/2" thickness is 1.36 lbs per sf.

Rubber Joint Expansion Joint material for concrete
is a processed board product formed by blending
granular rubber derived from discarded tires and various
low density polymer components. Premolded under heat
and pressure, it is more durable than current alternatives.
Suitable for use as expansion or control joint in a wide
variety of concrete construction projects such as
roadways, airport runways, sidewalks, driveways, flooring,
parking lots, patios and curbs.
Conforms to:
ASTM D-1751-97 and ASTM D-1752-84
AASHTO M-153-98 and AASHTO M-213-95
