Kadappa Stone – Complete Guide, Uses, Finishes & Prices (2025)

What Is Kadappa Stone?

Kadappa stone is a natural limestone quarried in Andhra Pradesh. It is used widely because it offers strong durability, natural grip, and a premium charcoal-to-black finish. As a result, it has become a preferred flooring and outdoor stone across India.

Names and Regional Variants

Kadappa stone is also known by several regional names. These include:

  • Black Limestone

  • Madras Black Limestone

  • South Indian Limestone

Although the names differ, the stone is the same natural limestone.

How Kadappa Stone Is Formed

Kadappa stone is formed naturally over thousands of years. Layers of minerals settle inside ancient water bodies. Over time, pressure compresses these layers. Eventually, chemical and physical changes harden the material into strong limestone. Because of this long formation process, colour and texture variations are normal.

Key Identification Features

  • Grey when dry

  • Deep black when wet

  • Natural riven or leather texture

  • High slip resistance

  • Uniform layers

These features make black  limestone easy to identify.

Appearance and Texture

Black Limestone appears charcoal grey in dry conditions. However, it turns deep black when wet. Its surface has a rugged and naturally grippy texture. Since each slab forms naturally, slight variations create a unique look.

Installation Guidelines

To maintain black limestone  properly:
