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.

1. An expansion joint system, comprising: foam;a fire retardant material infused into the foam; andwherein the expansion joint system is configured to facilitate compression of the system when installed between substrates, wherein the foam has a density when installed in a range of about 200 kg/m3 to about 700 kg/m3, and the system is capable of withstanding exposure to a temperature of about 540° C. at about five minutes, and the fire retardant infused foam is configured to pass testing mandated by UL 2079. 2. The expansion joint system of claim 1, wherein the foam uncompressed has a density of about 130 kg/m3 to about 150 kg/m3. 3. The expansion joint system of claim 1, wherein the foam has an infused foam density when compressed in a range of about 400 kg/m3 to about 450 kg/m3. 4. The expansion joint system of claim 1, wherein the system is configured to withstand exposure to a temperature of about 930° C. at about one hour to pass the UL 2079 testing. 5. The expansion joint system of claim 1, wherein the system is configured to withstand exposure to a temperature of about 1010° C. at about two hours to pass the UL 2079 testing. 6. A method of installing an expansion joint system utilizing the expansion joint system of claim 1, comprising: locating a first substrate of the substrates;locating a second substrate of the substrates arranged to be at least substantially coplanar with the first substrate and being spaced therefrom by a gap;inserting the expansion joint system into the gap between the first substrate and the second substrate; andallowing the expansion joint system to decompress to fill the gap between the first substrate and the second substrate. 7. The method according to claim 6, wherein the foam has an infused foam density when compressed in a range of about 400 kg/m3 to about 450 kg/m3. 8. A fire resistant expansion joint system, comprising: foam;a fire retardant material put into the foam; andwherein the fire resistant expansion joint system is configured to be installed in a gap between substrates and configured to facilitate compression during use to accommodate movement of the substrates as the fire resistant expansion joint system repeatedly cycles by expanding and contracting in the gap, wherein the foam has a density when installed in a range of about 200 kg/m3 to about 700 kg/m3, and the fire resistant expansion joint system is configured to maintain fire resistance upon exposure to a temperature of about 540° C. at about five minutes, and the foam with the fire retardant material is configured to pass testing mandated by UL 2079. 9. The fire resistant expansion joint system of claim 8, wherein the foam with the fire retardant material uncompressed has a density of about 130 kg/m3 to about 150 kg/m3. 10. The fire resistant expansion joint system of claim 8, wherein the foam with the fire retardant material compressed has a density in a range of about 400 kg/m3 to about 450 kg/m3. 11. The fire resistant expansion joint system of claim 8, wherein the system is configured to maintain fire resistance upon exposure to a temperature of about 930° C. at about one hour to pass the UL 2079 testing. 12. The fire resistant expansion joint system of claim 8, wherein the system is configured to maintain fire resistance upon exposure to a temperature of about 1010° C. at about two hours to pass the UL 2079 testing. 13. A method of installing a fire resistant expansion joint system utilizing the fire resistant expansion joint system of claim 8, comprising: locating a first substrate of the substrates;locating a second substrate of the substrates, the second substrate being spaced from the first substrate by a gap;inserting the fire resistant expansion joint system into the gap between the first substrate and the second substrate; andallowing the fire resistant expansion joint system to decompress to fill the gap between the first substrate and the second substrate, and the fire resistant expansion joint system facilitates compression during use after installation and accommodates movement of the substrates as the fire resistant expansion joint system repeatedly cycles by compressing and decompressing in the gap. 14. The method according to claim 13, wherein the foam with the fire retardant material compressed has a density in a range of about 400 kg/m3 to about 450 kg/m3. 15. A fire resistant expansion joint system, consisting essentially of: foam;a fire retardant material put into the foam; andwherein the fire resistant expansion joint system is configured to be installed in a gap between substrates, wherein the foam has a density when installed in a range of about 200 kg/m3 to about 700 kg/m3, and the fire resistant expansion joint system is configured to facilitate compression during use to accommodate movement of the substrates as the fire resistant expansion joint system repeatedly expands and contracts in the gap, and is configured to maintain fire resistance upon exposure to a temperature of about 540° C. at about five minutes, and the foam with the fire retardant material is configured to pass testing mandated by UL 2079. 16. The fire resistant expansion joint system of claim 15, wherein the system is configured to maintain fire resistance upon exposure to a temperature of about 930° C. at about one hour to pass the UL 2079 testing. 17. The fire resistant expansion joint system of claim 15, wherein the system is configured to maintain fire resistance upon exposure to a temperature of about 1010° C. at about two hours to pass the UL 2079 testing.
