Earth Blocks General FAQ's

What are Earth Blocks?
Earth Blocks are known as Compressed Stabilized Earth Blocks (CSEB), Compressed Earth Blocks (CEB), or Compressed Soil Mud Blocks (CSMB). The production process involves mixing soil (silt, clay, and sand) with Portland cement (6-9%) and water to achieve optimal moisture content. The mixture is then compressed in a hydraulic press to form blocks, which are cured for 21-28 days to reach their full strength.


- Earth Blocks = CSEB = CEB = CSMB

- Made from soil (silt, clay, sand) + cement + water  (Blended with our secret recepie)

- Compressed in a hydraulic press

- Cured for 21-28 days to reach full strength
What kind of soils are used to manufacture Earth Blocks?
Not all soils are suitable for making Earth Blocks, and the ideal soil composition for Compressed Stabilized Earth Blocks (CSEB) is more sandy than clayey. The optimal soil mix for CSEB consists of:

- 15% Gravel

- 50% Sand

- 15% Silt

- 20% Clay

While it's rare to find soils with this exact composition, Earth Blocks India's professionals can modify and utilize various soils to produce high-quality CSEB, with our knowledge and expertise.
Where do you source your Soil?

We source our soil locally, within a 4-8 kilometer radius of our manufacturing facility. Our soil is obtained from construction sites where excavations are being done for apartment basements. By utilizing this soil, we divert it from being sent to landfills, dumped on roadsides, or disposed of in water bodies, reducing waste and promoting sustainability.

Are Earth Blocks Burnt?

Unlike traditional bricks, Earth Blocks are not burnt or fired in kilns. Instead, they are simply cured with water after manufacturing, eliminating the need for burning wood or other materials. This eco-friendly process ensures no deforestation, no air pollution from smoke, and a significantly reduced carbon footprint.

Are Earth Blocks compressed manually?

Unlike traditional manual compression methods, Earth Blocks are manufactured using a hydraulic press to ensure superior quality, enhanced durability, and crisp, straight edges. This advanced technology allows for precise control over the block-making process, resulting in consistently high-quality Earth Blocks.

Earth Blocks Appearance, Strength and Durability FAQ's

How do we finish Earth Blocks?
Earth Blocks offer versatile finishing options to suit various architectural designs and client preferences. Pointing is a standard requirement for all Earth Block constructions, ensuring a sturdy and durable structure. Additionally, finishes can include waterproofing, plastering with mud, lime, or cement-based plasters, providing a wide range of aesthetic and functional choices for the final finish.
Can we paint Earth Blocks?
While Earth Blocks can be painted with lime-based, cement-based paints, or clear coats, it's important to note that painting may not be the best option. Each type of paint has its pros and cons, and it's recommended to avoid painting altogether to preserve the natural beauty and durability of the Earth Blocks. Instead, applying a waterproofing coat is a better option to protect the blocks while maintaining their natural finish.
Can we get uniform coloured Earth Blocks?

Earth Blocks may not have a uniform color due to the natural variability of soil. Soil is a complex mixture of minerals and organic matter, which affects its color. Even soil from the same source can exhibit color variations every few feet, making it challenging to achieve uniform-colored Earth Blocks. While the blocks delivered in one lot will have a consistent color, there may be variations in color over a longer duration, as new batches of soil are excavated and processed. Embracing this natural variation can lead to unique and characterful structures that reflect the local terrain.

Are Earth Blocks Strong?

Earth Blocks are exceptionally strong and outperform the compressive strength requirements outlined in Indian Standard Codes (IS: 1725) for soil-based blocks. In fact, their compressive strength surpasses the standards set for conventional building materials like burnt clay bricks (IS: 1077:1992) and concrete blocks (CMUs - IS: 2185-1:2005). This makes Earth Blocks a reliable and high-quality construction material, exceeding industry benchmarks for strength and durability.
