Expansion joint filler is a term used to describe a group of weatherproofing products intended for use as an aesthetic or functional expansion joint sealer agents in gaps in concrete slabs, walkways, decks, bridges, and sidewalks, for instance. Expansion joint filler materials are chosen for their ability to absorb impact and expand or contract along with the rest of the structure without cracking or separating.

Expansion Joints in Building/Construction

Expansion joints are generally joints or spaces left between slabs or construction elements of the same material to facilitate expansion and contraction due to changes in ambient temperatures. Although they serve their intended purpose well, they present several aesthetic and practical dilemmas. All of these issues may be addressed by inserting a joint sealant into the joint gap.

The material used for expansion joint fillers include low viscosity epoxy resins, and cork and woods such as southern yellow pine, redwood, or western cedar. Most liquid or gel sealants are self-leveling to ensure a flat, blemish free finish and may be painted or colored to match the rest of the structure. Epoxy sealants also offer excellent moisture, dirt, and plant exclusion protection. Depending on the expansion joint profile in question, these sealants are used often in conjunction with a rubber backing material inserted into the gap prior to sealing.
