In some cases, laying tiles can be difficult because of uneven floor foundations. As a result, tiles that seem perfectly level during installation may vary in height once the adhesive has cured. To avoid this, use a tile levelling system. These can be used for stone, ceramic, marble, granite and large format slab tiles. The system interlocks the tiles, creating a virtual single flat slab surface while the setting material is curing.
The interlocking system reduces settling from shrinkage and minimises warping. It reduces the need to re-lift tiles to add more adhesive, making installation a lot faster. The tile levelling wedges are also reusable.
