Durock is a brand of cement board commonly used in construction and remodeling projects. It is primarily designed as a substrate for tile installations, providing a stable and moisture-resistant surface. Durock is made from a mixture of cement and fiberglass mesh, making it durable and suitable for wet areas like bathrooms and kitchens. In addition to its use in tile applications, Durock can also be utilized for various other purposes, such as underlayment for flooring and as a backing for countertops. Its resistance to mold and mildew makes it a popular choice among builders and DIY enthusiasts for creating long-lasting, water-resistant surfaces.
