Sandstone is a sedimentary rock composed mainly of sand-size mineral or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Like sand, sandstone may be any color, but the most common colors are tan, brown, yellow, red, gray and white. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.
Some sandstones are resistant to weathering, yet are easy to work. This makes sandstone a common building and paving material. The formation of sandstone involves the accumulation of layers of sand as a result of sedimentation, either from water (as in a river, lake, or sea) or from air (as in a desert) for thousands of years. Finally, once it has accumulated, the sand becomes sandstone when it is compacted by pressure of overlying deposits and cemented by the precipitation of minerals within the pore spaces between sand grains.
Natural Stone, also known as Galana, Maji-ya-Chumvi, Mazeras slate or Crazy shape stone, is a classic example of African sandstone. It is mined from seasonal riverbeds in the form of slabs. Maji-ya-Chumvi means "salt water" in Swahili, and the stone Galana, or Mazeras slate, gets its name from the place where it's mined near the town of Mombasa.
Known also as Galana in the local language, the tile is used both externally and internally as the stone has a dense hardwearing surface and has structural properties similar to that of sandstone. The thickness has a tolerance of plus (+) or minus (-) 2mm. The tiles are sawn out of natural stone.
Galana is a versatile stone which can be put into many uses, and has been used extensively in residential houses, hotels and lodges throughout Kenya. One example is the Karen-Blixen hotels and lodges. Galana tiles can be used externally to lay paved pathways either in uncut slabs (crazy cut) or in random cut.
The stone is cut in slices from the bed rock. The widths of the slices vary according to demand and the shape varies naturally. However it is possible to have desired shapes according to customer request. The color shades of the tiles vary depending on the geological layer from which it is mined. The general shade of the tile ranges from brown, yellow, green and black slate with tones sometimes of rustic brown. The color-mix and rustique texture provides each stone with a unique expression, and they suit other more contemporary materials such as glass and steel extremely well.
Natural stone flooring lends a touch of class to formal entryways, or a rustic look to outdoors. No matter where you choose to install it, there is a type of stone flooring suitable for your style.
Natural stone tiles are top choice for wet areas. Because of their timeless design that never goes out of fashion, Natural stones are less likely to be removed and thrown out than ceramic tiles or vinyl.
Natural stone tiles are a great alternative for wet areas, and their natural beauty will last the life of the house and beyond.
