FLEXIBLE FOAM EXPANSION JOINT
Description
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
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 products, 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,
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.
