Measuring 4 inches wide by 50 feet long and 1\/2 inch thick, it provides a compressible, resilient filler between adjacent slabs, walls, or structural sections that must accommodate thermal movement and load cycling. The material is stiff enough to hold a straight line on linear joints yet flexible enough to conform to curved or contoured surfaces. It resists moisture intrusion and UV degradation, making it suitable for both interior and exterior installations. Licensed contractors and experienced concrete tradespeople are the primary installers.\u003c\/p\u003e\u003cp\u003eThis expansion joint strip is used wherever control and isolation joints are required in flatwork, slabs-on-grade, driveways, sidewalks, pool decks, curbs, and foundation walls. The 50-foot roll provides continuous coverage for longer joint runs, reducing the number of end-to-end splices. The 4-inch width suits standard joint depths in residential and light commercial concrete work. Its moisture and UV resistance make it a practical choice for outdoor exposed applications as well as below-grade conditions where ground moisture is present.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4 inches wide by 50 feet long roll for extended joint coverage\u003c\/li\u003e\n\u003cli\u003e1\/2 inch thickness provides consistent joint spacing and load distribution\u003c\/li\u003e\n\u003cli\u003eFlexible enough to shape around curves and contours\u003c\/li\u003e\n\u003cli\u003eResistant to moisture and UV exposure for interior and exterior use\u003c\/li\u003e\n\u003cli\u003eExceeds ASTM standards D4819 and D3575\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fit expansion joint for concrete flatwork, masonry, and structural joint applications requiring a 4-inch-wide, 1\/2-inch-thick compressible filler strip.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by concrete finishers, masonry contractors, or general tradespeople working with flatwork or structural concrete. Position the strip vertically within the form or saw-cut joint before the pour or placement of adjacent sections, ensuring the full depth of the joint is covered. No fasteners are required in most applications, as the strip self-supports within the form. Follow ACI 302 or applicable local concrete standards for joint spacing and depth requirements.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 50 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Foam\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUV Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMoisture Resistant\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: Exceeds ASTM D4819 and D3575\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: REFLECTIX INC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EXPO4050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"REFLECTIX","offers":[{"title":"Default Title","offer_id":51525309006130,"sku":"EXPO4050","price":174.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b646810083e0b62f02aafc95a5474d75.jpg?v=1785470266","url":"https:\/\/voomisupply.com\/products\/reflectix-inc-expo4050-foam-expansion-joint-4x50","provider":"Voomi Supply","version":"1.0","type":"link"}
