This Limestone flooring tile has blue grey tones, and a high concentration of shells and fossils within each tile. Marcella Blue Limestone flooring is very dense and it is therefore suitable for any high traffic areas such as entrance halls. It is excellent for anywhere a waterproof tile is required, such as washrooms and kitchens, due to its low porosity. When tiled with a tight grout joint, it can have the appearance of being an almost seamless floor or wall. This particular Limestone is becoming increasingly rare to source, as the quarry is finding it harder to find the rare blue slabs!
