CERAMAR®
FLEXIBLE FOAM EXPANSION JOINT
Provides recovery qualities of over 99%
with virtually no water absorption.
SEALTIGHT CERAMAR Flexible Foam Expansion Joint provides an excellent joint
filler and back-up material for either horizontal or vertical expansion/
contraction joints and for stress and pressure relief in concrete pavements.
Technical Description
SEALTIGHT CERAMAR Flexible Foam Expansion Joint Filler is 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
SEALTIGHT 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: Two excellent SEALTIGHT Products,
CERAMAR and GARDOX Horizontal Sealant, may be used together to provide an
excellent horizontal sealing system for plaza decks, sidewalks, driveways,
commercial and industrial floors. Refer to SEALTIGHT GARDOX Catalog 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.
