--- title: Important Cold Weather Installation Note | Grout Installation description: If temperatures are cold enough, the water will expand before the grout cures. This could cause the surrounding concrete, stone, or block to crack. --- [![Providing Structural and Miscellaneous Steel Fabricators](https://www.thesteelsupplyco.com/hs-fs/file-14727826-jpg/images/bannerfixed-webrdy.jpg?width=750&name=bannerfixed-webrdy.jpg "Providing Structural and Miscellaneous Steel Fabricators")](https://www.thesteelsupplyco.com/) - [![the steel supply company](https://www.thesteelsupplyco.com/hs-fs/hubfs/logo-1.jpg?width=88&name=logo-1.jpg "the steel supply company")](https://www.thesteelsupplyco.com/) - [![The Steel Supply Co, Inc](https://www.thesteelsupplyco.com/hubfs/top-text-new.png)](https://www.thesteelsupplyco.com/) - [![Specialized Supplies for Structural and Miscellaneous Steel Fabricators](https://www.thesteelsupplyco.com/hubfs/bottom-text-new.png)](https://www.thesteelsupplyco.com/) [Return to Hydraulic Cement and Non-Shrink Grout](https://www.thesteelsupplyco.com/steel-products/hydraulic-cement) # Important Cold Weather Installation Note **Water expands when it freezes.** All grouts are mixed with water. If the outdoor temperature is cold enough to freeze the water before the grout cures the water will expand. This could cause the surrounding concrete, stone, or block to crack. Water contracts like all liquids as it is cooled, until it reaches approximately 38 degrees Fahrenheit. As it continues to cool it expands slightly until it reaches 32 degrees Fahrenheit when it freezes. At that point it **expands 9%**. The force of water expanding can cause cracks like those shown in the picture. For this reason all grouts should be used carefully in cold weather.![Grout](https://www.thesteelsupplyco.com/hs-fs/file-14748451-jpg/images/img_1131-web.jpg) ### Follow the Steel Supply Co on Social Media! © 2015 The Steel Supply Company, Inc. * Office: 35 Pine Drive, Cold Spring Harbor, NY 11724 * Warehouse and Factory: 109 Kean Street, West Babylon, NY 11704 * Phone 631-385-7273 * Fax 631-385-7274 info@thesteelsupplyco.com
