Types of Natural Stone Flooring
- Slate is another form of metamorphic rock that consists of silica alumina and iron oxide.
- It is easily split into layers that provide a rugged rustic look.
- It has good abrasion resistance and high durability if it has been correctly cut.
- It is impervious to water, cold hard and noisy under foot and can be slippery.
- A non-slip variety is available.
- It is difficult to lay as the product is quite brittle and heavy.
- It is usually laid into a bed of cement over concrete.
Limestone and Sandstone
- These are derived from sedimentary rocks; deposits of sediment being laid down under water or air formed these.
- Sandstone comes from deposited sand grains i.e. quartz, pressed and held together by silica, calcium carbonate or other cements.
- Limestone comes from deposited organic origin materials i.e. bones shells and consists mainly of calcium carbonate.
- Limestone is rarely used for floors today as it becomes slippery when it is worn and not all products are hardwearing.
- It is grey or beige in color.
- Sandstone - is used more in outdoor paving than indoor, but looks great in an area that flows to the outdoors such as a conservatory.
- Its irregular natural pattern is its best feature and can range from a grainy timber look to stripes and speckles.
- It is beige, brown, reddish brown, in color and some stones are hardwearing.
- Granite is a form of Igneous Rock, created by the cooling of molten magma.
- It is made up of feldspar quartz and mica.
- This is a luxury floor covering and one that needs careful consideration before specification, as it is an expensive product.
- The floor structure needs consideration, as it is very heavy.
- Once laid, it will last for a very long time, as it is hardwearing and resistant to chemicals.
- It has a timeless look.
- If highly polished it is slippery, but a honed finish provides a more manageable finish.
- It comes in limited colors - black, red, green, grey, blue, pink.
- It is supplied in a slab form and is cold and noisy underfoot. But it looks great!
- This is a form of metamorphic rock, a combination of igneous and sedimentary rocks undergoing a major change due to extreme influences of heat or pressure.
- It is made up of calcium carbonate; it comes in numerous colors, white, grey, green, ochre, beige and is usually veined.
- It is a hardwearing beautiful product, expensive to purchase and lay as it is heavy and comes in slab form.
- It is cold and noisy underfoot.
- From a designers point of view like granite it has a timeless quality.
