DESCRIPTION
A.P.S. Self-Expanding
Cork is a pre-molded expansion joint filler for concrete, made of granulated
cork particles, securely bonded together with an insoluble resin binder.
A.P.S. Self-Expanding Cork is specially treated to allow up to 40% expansion
beyond its original thickness after installation.
USE
A.P.S. Self-Expanding
Cork should be used in all concrete joints subject to excessive contraction,
as could occur in dams, sewage treatment plants, waste water plants, flood
walls, spillways, and power plants.
APPLICATION
A.P.S.
Self-Expanding Cork should always be installed as detailed on the drawings.
Because of a unique treatment used on A.P.S. Self-Expanding Cork, it will
not expand prematurely under normal atmospheric conditions. Thus, unlike
many other self-expanding cork materials, it can be field cut on the jobsite
to the exact size required. The convenient 2' x 3' sheet size makes A.P.S.
Self-Expanding Cork easy to handle by field personnel. After installation,
if sufficient moisture is not present in the adjacent concrete, clean,
hot water should be applied to the exposed edges of the cork during the
first 48 hours to facilitate expansion.
PACKAGING
Thickness:
3/8", 1/2", 3/4", 1"
Width: 3" to 24"
Length: 3'
A.P.S. Self-Expanding
Cork is wrapped in moisture proof paper. The factory packaging should
not be opened until cutting and/or installation is required. Do not expose
to rain or moisture after opened. A.P.S. Self-Expanding Cork will not
prematurely expand under normal atmospheric conditions.

CONFORMANCE
ASTM D1752,
Type III
AASHTO M153, Type III
ADVANTAGES
OF A.P.S. SE CORK
Field installation
will not be compromised due to broken pieces with rough edges butted together.
1. Our easy
to handle 2'x3' sheets virtually eliminate broken sheets and therefore
provide for a 100% filled concrete joint.
2. On jobsite
cutting enables the contractor to always have on hand the exact size required.
Cutting on the jobsite eliminates overbuying of various sizes.
3. Compatible with most cold and hot applied joint sealants.
4. Expands
up to 140% and compresses up to 50% of its original thickness keeping
the joint 100% filled at all times.
5. Will not
prematurely expand under normal atmospheric conditions.
SUGGESTED
SPECIFICATION
The expansion
Joint filler shall be premolded composed of granulated cork particles,
securely bonded together with an insoluble resin binder. The premolded
self-expanding cork joint filler should be specially treated to allow
up 40% expansion beyond its original thickness after installation. The
self-expanding cork shall have a thickness of not less than 140% of its
original thickness after immersion in boiling water for one hour.
The premolded
self-expanding cork Joint filler shall be of the same thickness as shown
on the plans and shall conform to ASTM D1752, Type III. The self-expanding
cork filler as specified herein shall be A.P.S. Self-Expanding Cork by
A.P.S. Supply Co. Beverly New Jersey 08010.
