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.

Specifications
CERAMAR meets the requirements of ASTM D 5249, Type 2, ASTM D 1752, Sections 5.1 through 5.4, with the compression requirement modified to 10 psi (7.03 g/mm²) minimum and 25 psi (17.58 g/mm²) maximum. It is non-gassing and is compatible with hot-pour joint sealants.

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.
