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.
