Marmox Sloping Boards are pre-formed, waterproof boards designed to create accurate and consistent falls to waste in tiled wet areas, balconies, terraces and decks. Manufactured with an extruded polystyrene (XPS) core and reinforced polymer-cement coatings on both sides, they provide a stable, tile-ready substrate for bathrooms and balconies. The board tapers from 33mm down to 10mm to deliver a continuous one-way fall. Supplied as a Box of 2 boards.
By eliminating the need for traditional screeding, Marmox Sloping Boards reduce installation time while delivering reliable drainage performance and long-term durability. They are compatible with the wider Marmox Multiboard system and can be paired with 20mm flat Multiboards to extend the slope across larger areas.
