A fire resistant and water resistant expansion joint system comprises a compressed lamination of fire retardant infused open celled foam, one coat of an elastomeric waterproofing or water resistant material on the lamination, and another coat of an intumescent material on an opposing surface of the lamination, thereby providing fire resistance in one direction and water resistance in the opposite direction. The intumescent material may be further coated with a similar elastomeric material, thereby providing fire resistance in one direction and water resistance in both directions. In the alternative, the compressed lamination may comprise first and second opposing layers of intumescent material thereon each having a respective layer of elastomeric material to provide both water resistance and fire resistance in both directions.
