Backer Boards
Waterproof. Lightweight. Cut-to-Fit. Built to Last
When it comes to tile-ready surfaces, not all backer boards are created equal.
HYDRO-BLOK Backer Boards deliver the same precision engineering and reliability as our full line of waterproofing products — giving you a 100% waterproof, cut-to-fit foundation that installs fast.
The HYDRO-BLOK Advantage
Every backer board features a 100% waterproof XPS closed-cell foam core, reinforced with fiberglass mesh, and finished with a modified cement coating — creating a superior bonding surface for tile, stone, glass, or mosaic finishes.
Lightweight yet incredibly strong, these boards can be cut with a utility knife, hand saw, or small circular saw, allowing you to create custom shapes, curves, and corners with ease.
