Flexible Expansion Joint
CERAMAR Flexible Foam Expansion Joint Filler is composed of a unique synthetic foam of isomeric polymers in a very small closed cell structure. Grey in colour, CERAMAR is a lightweight, flexible, highly resilient material offering recovery qualities of over 99%. The compact closed-cell structure will absorb almost no water.
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.

For horizontal applications, position CERAMAR against the forms; at interrupting columns and objects or adjacent to abutting structures before placing 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.
Proper application is the responsibility of the user. Field visits by W. R. MEADOWS’ personnel are for the purpose of making technical recommendations only, and are not to supervise or provide quality control on the job-site.
Due to its light weight, CERAMAR will float and must be held in place by compression or with a sealant.
