Stones are a very common material used in construction both internally and externally. Stones are a naturally occurring material that is sustainable and hence recommended for use in green design. The stone properties are what makes it be categorized as one that is good for use indoors or outdoors. Stones have over the years been used for construction of houses, temples, tombs etc. Due to this, different technologies have emerged to assist in harvesting, shaping, and finishing the stones for appropriate use.
The distinctive qualities of stone are due to the complex geological processes that occur during its formation. The stones formed under high heat and pressure are strong and can be used outdoors and as foundation elements.
As an Interior designer, stones are materials that I largely use in my projects. They are used as floor and wall finishes as well as countertop, fireplace, and staircase cladding. I love the natural look of materials and therefore, I prefer using stones in their natural occurring state, colour, and finish. Stones can be polished or honed and the selection of either is based on the intended use.
There are
over 8 types of stones used in construction. These are and not limited to:
- Basalts
- Granite
- Sandstone
- Slate
- Limestone
- Marble
- Quartz
- Travertine
- Onyx
- Gneiss
a. Basalts
Basalts can achieve a variety of thicknesses and therefore, machine cut basalt stones can be used as an interior or exterior cladding material.
Second to Basalt, Granite is also a hard and impervious stone. Due to its formation, granite is extremely heat, scratch and chip resistant. This makes it an excellent material for use indoors and outdoors. It being chip resistant, it is largely used as a floor material outdoors. Polished granite can be used at the entry porch, round the house corridors and even courtyards. Honed granite can be used in driveways, walk-ways and garages. In Interiors, it is a perfect material for use as kitchen and bathroom counter tops. The most common colours are black, white, green, blue, grey, red, pink and brown. Granite however has poor resistance to fire.
c. Limestone
Limestone is a much softer stone. It is of sedimentary nature and is made of calcium carbonate. In structure, limestone is fine textured. Its colours range from pure white (chalky) to grey and dark varieties. Not all limestones are useful in construction; some are too soft and brittle. Limestone that is usable is dense, compact and fine textured. Since it’s quite porous and reactive to chemicals, it should not be used in areas where the air is polluted with industrial gases or in coastal regions directly exposed to salty water. The best use of Limestone is as a tile both on floors and walls and as a cladding material. Locally, the most commonly observed limestone is Mazeras; generally used as an entry area or poolside tile and Coral stone; mostly used as a cladding material. Limestone is produced in a honed finish since its brittle nature does not allow it to be polished.
d. Marble
Marble is a metamorphic rock formed when
limestone is subjected to high heat and pressure. It is softer than Granite but
harder than Limestone. In the past, marble was commonly used for facing and
ornamental work such as decoration of monuments, sculptures and columns. Marble
can be polished to an almost glass look. Due to this, it is considered a very elegant
product and therefore used in high end projects such as hotels, residential
houses and palaces. Marble is porous and easily stains and therefore, one should
be careful when handling it as a Kitchen top and floor tile. Avoid spilling
turmeric, beetroot or food stain in the kitchen. One should also be careful not
to step on it with muddy shoes as the red soil will leave stains.
