Slate reserves in India are found in Rajasthan, Haryana, Himachal Pradesh, Andhra Pradesh, and Madhya Pradesh. Deposits in Rajasthan are spread over the districts of Alwar, Ajmer, Bharatpur, Tonk, Sawai Madhopur, Pali, Udaipur, Churu, and Chittorgarh.
The slate from Rajasthan and Andhra Pardesh is very popular for interal wall cladding and also for flooring. It is most suitable for low traffic area. The unique rustic look of slate is ideally for creating a warm look and is sought by architects from around the world.
Slate found extensively, throughout north and south India and for centuries, has been a major source of building stone. Historically, and, in common with other stones, it was first used in and around the immediate areas of availability.
The term slate is often used to describe any rock that can be easily split into thin sheets, principally for roofing purposes. True slate is defined by the presence of a 'slaty' cleavage; this allows the slate to be split at almost any point through the stone parallel to the cleavage plane. Most true slates are metamorphosed sediments, often formerly mudstones.
The main deposits of slate are found in South India in the region of Markapur(Andhra Pardesh) Deoli in North( Rajasthan) and Kund in north ( Himachal Pardesh) . There various colours of slate found in south and north.
From the very early, basic applications, Indian Slate is now used for very wide and diverse purposes. Modern quarrying and machine processes allow prime blocks to be sawn or split into large slabs and a variety of thicknesses. Current products include: roofing, cladding, cills, copings, flooring & paving, treads, plaques & memorials, worktops & fireplaces.
Slate is typically a very durable construction material and rarely exhibits visible degradation, even when placed under extreme atmospheric conditions for many years. For flooring purposes some Indian slate is unlikely to delaminate or exhibit efflorescence.High flexural strength and typically very low porosity makes slate eminently suitable for flooring purposes and it requires little maintenance.
Caution should be exercised when choosing material marketed as slate as some may not be suitable for flooring. If any doubt exists about the material being considered, specialist advice should be sought.
Very thin, split, natural riven sections are used for roofing and the same methods produce thicker material for flooring and cladding. Slateis readily available in sawn, fine rubbed and other finishes such as sand-blasted and flame textured.
Indian Slate has a proven record of durability and being supplied fit for its intended purposes. This is readily seen on countless buildings in the UK and many areas of the world. Such examples of installation are witness to the ability of slate to withstand the rigours of extreme atmospheric conditions. Slate is extremely stable and will not degrade, warp or twist. Quality Assurance, management systems are widely used throughout the industry.
