Abstract

An expansion joint seal system which includes intumescent to protect uncoated edges of substrates. A fire rated compressed expansion joint sealant is provided having an intumescent proximate, but below the water-resistant top of the fire-retardant foam, so that when exposed to fire, the intumescent expands to protect the exposed vertical surface of the adjacent concrete substrate. The end of the concrete is therefore protected in a manner which does not require joint overlap between the horizontal fire resistant coating and the compressible sealant.
