Earth Bricks are made locally, reducing cost, and making the dream of a Brick house possible.



Interlocking Bricks, also called Earth Bricks, is a strong and earthquake resistant building material. It is a proven earthquake resistant technology which has been used for decades in earthquake affected areas across India, Pakistan, Iran and many other countries. It enables to build high quality and earthquake resistant structures at low cost.


What are Interlocking Bricks (CSEB) made of?


Interlocking Bricks consists of Soil, Sand and 10% Cement. The mixture is compressed in a machine which results in a compacted brick with high density. The bricks are then stacked and cured for 21 days – the cement sets and bonds with the sand stabilizing the brick. The soil compresses, which adds to the high density and strength. An Interlocking Bricks has the same behavior and mechanical properties as concrete or ordinary fired bricks.

The precise composition of the soil should be around 50% sand, 20% clay, 15% gravel and 15% silt. Normally we don’t get this exact soil in a village, so first the soil is tested and then we add sand and gravel until we have this ratio. This way we can ensure the same bricks strength in any village.


Advantages of CSEB

Earthquake resistant. 

The bricks are reinforced by iron rebar inside the wall, both horizontally and vertically, making it highly earthquake resistant.

Local material & opportunities 

The bricks are made in the village using only Sand, Soil and Cement. It also creates opportunities for local entrepreneurs.


Locally made high-quality bricks, saving cost and creating local jobs

Eco friendly. 

60% less CO2 emissions compared to fired bricks!



How much does it cost to build with Earth Bricks?

Every village is different and the cost therefore varies with local conditions. The cost depends on the following factors:

The size and design of the building

The accessibility of the site

Cost of materials in the local market

Cost of labour

Earthquake resistance

Interlocking Bricks (CSEB) is an earthquake resistant technique that has been used for many decades. The bricks made by our Heavy Duty machine (24x24x9cm) has a compressive strength of more than 10 MPA, which is better than A-grade bricks. Our smaller Interlocking machine has the same compressive strength as regular kiln fired bricks.

When building , utilize the Interlocking Brick Masonry and reinforce the walls with rebar, both horizontally and vertically, adding to the strength and making the structure earthquake resistant.

Vertical rebar are put in each corner, at doors and windows and evenly spaced throughout the walls. This is then connected with horizontal seismic bands making the whole structure interconnected and earthquake resistant.
