When it comes to filling gaps and cavities in concrete slabs and walls, flexibility is key. Our Jumbolene Expansion Joint Fillers are designed to expand and contract as needed, ensuring a seamless fit that accommodates natural building movements without compromising stability.

Jumbolene® Expansion Joint Filler is a flexible, compressible, closed cell polyethylene foam filler for structural expansion joints and building facades. This product extends the service life of concrete by acting as an insulator to contraction and expansion joints. It is a chemical-resistant expansion joint filler and is compatible with all cold-applied joint sealants.
