The development of waterproof, backing boards for tile installation by UK companies is highlighted. N&C Nicobond has launched Nicobond Lux, an ultralight foam core that is combined with a glass fibre-reinforced mortar layer on both sides to produce a smooth, ready-to-tile, waterproof substrate for walls and floors. James Hardie Industries has developed Hardibacker, a high-performance, water-resistant, cementitious tile backing board for walls and floors. In addition to these developments, Schluter Systems is marketing a new floor drainage system for tiling installations. Kerdi-Drain is specially designed for use in thin-bed tile or natural stone installations and can be fitted to screed or suspended timber floors. It achieves a secure, bonded waterproofing between the drainage outlet and the membrane.
