CERAMAR®
Flexible Foam Expansion Joint
DESCRIPTION
CERAMAR is a flexible foam expansion joint
filler composed of a unique synthetic foam of
isomeric polymers in a very small, closed-cell
structure. Gray in color, CERAMAR is a
lightweight, flexible, highly resilient material
offering recovery qualities of over 99%. The
compact, closed-cell structure will absorb almost
no water.
USES
CERAMAR flexible foam expansion joint filler
provides an excellent joint filler and back-up
material for use in either horizontal or vertical
applications where expansion and contraction
movements must be accommodated. CERAMAR
is compatible with all currently popular cold-applied
sealants, caulks, and hot-pour joint
sealing compounds. It is lightweight and easy to
cut or form in the field without waste.
CERAMAR compresses easily for use with
shrinkage-compensating concrete and it may be
used to relieve stress and pressure in concrete
pavements.
HIGHLY FUNCTIONAL JOINTING AND
SEALING SYSTEM: CERAMAR and
GARDOX® horizontal sealant from W. R.
MEADOWS may be used together to provide an
excellent horizontal sealing system for plaza
decks, sidewalks, driveways, and commercial and
industrial floors. Refer to GARDOX
Data Sheet No. 226.

APPLICATION
For horizontal applications, position CERAMAR
against the forms, at interrupting columns and
objects or adjacent to abutting structures, before
placing the concrete. Vertical applications may
call for CERAMAR to be placed between panels,
panel-to-column joints, or in block wall joints
prior to sealing. CERAMAR may be used with
all hot- and cold-applied sealants.
PRECAUTIONS
Due to its light weight, CERAMAR will float and
must be held in place by compression or with a
sealant.
Health and Safety
Refer to Material Safety Data (MSDS)
for complete health and safety information.
