Achieving a consistent gradient for effective water runoff is a critical challenge in modern bathroom and outdoor construction. Marmox Sloping Board offers a pre-formed solution, eliminating the need for complex screeding or heavy concrete work.
Built with the same high-density, insulating XPS core as the famous Multiboards, these sloping panels offer unmatched quality control. The surface is treated with a specialised textured polymer concrete, reinforced with carbon nanotubes and glass fiber. This creates a rock-solid, 100% waterproof foundation that makes tiling faster and more secure than ever.
Designed specifically to extend the slope of a showerlay or to act as a standalone pre-sloped flooring solution, this sloping board provides a uniform taper. If you need to extend the area further, a standard 20mm thick Marmox Multiboard can be placed under the thin edge (10mm + 20mm = 30mm) to continue the fall, or a 33mm thick board can abut the thick edge. Whether used for a wetroom floor, balcony or terrace, or a communal shower, these sloping boards ensure a seamless surface ready for tiling.
Key Features
- Lightweight and Easy to Cut: Unlike traditional concrete screeds, this construction board is lightweight and can be easily trimmed to size using a standard craft knife or saw.
- Ready for Tiling: You can have the surface tiled directly onto using a flexible tile adhesive. The surface is designed to prevent crack transmission from the subfloor to the tiles.
- Versatile Extension: Can be combined with 20mm or 33mm standard Multiboard to extend the slope over larger areas.
- Load Bearing: capable of supporting substantial weight, making it suitable for residential and commercial bathroom environments.
