Cement Tile Backer Boards
Strong, Waterproof & Built for Tiling
Our Cement Boards
Cement tile backer board is a durable, moisture-resistant board designed to provide a stable foundation for wall and floor tiling. Unlike standard plasterboard or plywood, cement-based boards are specifically manufactured to withstand water exposure, heavy tiles and high-traffic areas without swelling, warping or breaking down over time.
Whether you are installing tiles in a bathroom, wet room, kitchen or on a floor with underfloor heating, cement tile backer board creates a rigid, long-lasting base that prevents tile movement and cracking.
If you’re looking for a reliable, waterproof solution for professional or DIY tiling projects, cement backer board is the industry-standard choice.
What Are Cement Tile Backer Boards?
Cement tile backer boards are made from a reinforced cement core, often combined with fibreglass mesh for additional strength. It is designed specifically as a substrate for tiles in areas exposed to moisture.
It is commonly used in:
- Bathrooms
- Wet rooms
- Shower enclosures
- Kitchen splashbacks
- Tiled floors
- Areas with underfloor heating
Because it does not deteriorate when exposed to water, it is ideal for installations where long-term durability matters.
Why Use Cement Tile Backer Boards Instead of Plasterboard?
Using plasterboard behind tiles in wet areas can lead to long-term issues. Cement tile backer board offers significant advantages:
1. Waterproof & Moisture Resistant
Unlike plasterboard, cement boards do not absorb water, making them ideal for bathrooms and wet rooms.
2. Strong & Rigid
They provide a solid base that reduces tile movement and prevents cracking.
3. Suitable for Floors
Cement backer boards can be used on floors to increase rigidity before tiling.
4. Compatible with Underfloor Heating
Perfect for use over electric underfloor heating systems, helping distribute heat evenly beneath tiled floors.
