What is durock?

Durock is a brand of cement board used as an underlayment for tile, stone, and other finishes in both interior and exterior applications. It is manufactured by USG Corporation, a leading building products company.

Durock cement board is made from a mixture of cement, water, and reinforcing fibers. The fibers, typically fiberglass, are dispersed throughout the board to enhance its strength and durability. The cement composition makes it highly resistant to moisture, mold, and mildew.

One of the main uses of Durock is as a substrate for tile installation. It provides a solid and stable surface for tiles, preventing any movement or cracking. Durock can also be used for other finishes such as stone veneer, stucco, and brick.

Durock comes in various thicknesses, typically ranging from 1/4 inch to 1/2 inch, allowing for different applications and load requirements. It is available in different sizes, including 3x5 and 4x8 feet sheets.

Installation of Durock involves cutting the boards to size, attaching them to the underlying surface using the appropriate fasteners, and then sealing the seams and edges with a cement mortar or tape. Once installed, it is essential to follow proper waterproofing and tiling procedures to ensure a long-lasting and durable finish.

Overall, Durock cement board is a reliable and widely used product in the construction industry. Its moisture resistance, strength, and stability make it an excellent choice for tile and other finish installations.
