For self-draining tiled areas such as balconies or wetrooms
Marmox Sloping Boards are made from the same waterproof, thermally insulating XPS sandwiched between two layers of our patented polymer-concrete as a Multiboard. The boards have undergone rigorous tests to ensure they are suitable for external use so can be used on the most exposed balconies as well as inside a wetroom.
The board is made in just one size, 1200 x 1200mm. The thickness of one edge is 33mm and this slopes down to 10mm at the opposite edge. They can be combined with 20mm thick Marmox Multiboards to extend the slope indefinitely.
• Tileable balconies
• Tiled areas where a gentle slope is required
• Wetrooms with channel drainage against the wall
Decoupling and Waterproofing
External balconies are subject to the extremes of temperature fluctuation. Tiling these areas can be difficult as the substrate expands and contracts with the temperature which can lead to tiles cracking. Marmox Sloping board absorbs a large amount of the lateral movement in the sub floor making tiling a balcony a safer prospect.
Like all Marmox Multiboards, the sloping board is completely impermeable to water and so if carried out to Marmox’s instructions, a guaranteed leak-free balcony can be tiled above a habitable space.
