Marmox Sloping Board is an XPS foam board coated on both sides with a polymer-concrete layer. 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. External balconies are subject to temperature fluctuation and 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. As well as acting as a decoupling layer the boards are impermeable to water and can therefore act as a waterproofing layer too.

Marmox Sloping Board measures 1200 x 1200mm and slopes from 10mm at one end to 33mm at the other. They can be combined with 20mm thick Marmox Multiboards to extend the slope indefinitely.

Fixing onto bitumen, roofing grade asphalt or damp proof membrane on a balcony or roof terrace? Use Marmox Sloping Board with Norcros Ultim8 B+ adhesive.

At Green Garden Paving we are passionate about porcelain. As UK market leaders in the supply of porcelain paving, we stock a variety of vitrified products suitable for a range of landscaping and architectural projects. We have over sixty years experience in the tile industry, which gives us valuable knowledge and experience in working with porcelain. We believe that porcelain cannot be treated in the same way as traditional paving products, which is why we recommend different installation methods to many of our competitors who specialise in natural stone or concrete paving.

All external porcelain at Green Garden Paving is a minimum of 18mm thick with R11 rated slip resistance. We offer full or cut samples and delivery is free on all orders over £300 (ex VAT). Products are available from stock in our Hampshire warehouse, where you can also view our external porcelain display garden which has been installed using the PorcelQuick Adped system. If you have any questions please do not hesitate to contact one of our friendly team for advice.
