about us

Wanju Construction is about helping the housing system that has been critical and costly to afford, into a more enviromentally conscious structures and into a cost effective way. We use the age old method of Earth Block which is modified into a Technology. This new innovative technology is the improvement of age old earth construction methods which are cheaper and durable. Cheap does not mean low quality and costly does not mean high quality. Quality can be obtained even in low cost with innovative technology by utilizing it efficiently. We help in proper use of the local resources to bring quality without adding much cost. Thus providing people with their right to live in a safe, comfortable and enviromentally friendly house.

  • Supply of Hollow Interlock Compressed Stabalized Earth Block

    The soil, raw or stabilized, for a compressed earth block (CEB) is slightly moistened, poured into a steel press (with or without stabiliser) and then compressed either with a manual or motorized press.

Why Earthblocks?

Earth Blocks often referred to as compressed earth blocks (CEB) or Compressed stabilized earth blocks (CSEB) or Hollow Interlock Compressed stabilized earth blocks (HI CSEB), which are a high quality construction material made from locally sourced soil containing clay. With proper mix design and a small percentage of cement.


The properly mixed soil and given the provided strength by pressuring it with strong quipment produces blocks which can even compete the best quality burnt bricks. It provides system for reinforcement structures too thus making it suitable for seismic zones too.

Long History

The oldest building material ever known to man is the dirt underneath our feet. The oldest buildings in the world where people are still residing are made out of earth. Even ancient cities in Nepal witnesses earthern houses.


Earth Blocks are healthy because it is natural and does not emit toxic gases like other building materials do. Earth Blocks provides a natural system to regulate heat and humidiy inside the structures they create.

Environmentally Friendly

Earth Blocks cut off the use of fire as in burnt bricks thus adding a value to the enviroment. It has the smallest carbon footprint in all the building materials. It naturally regulates the temperature and humidity in the room which will lessen the energy consumption.

Cost Effective

Earth Blocks can be produced locally which helps to eliminate the transportation costs. The dimensions of the Block is slightly larger than the normal burnt bricks which makes the building process faster and less mortage is used.


Earth Blocks are durable which is highly able to resist wear and decay that exist for a long time without significant deterioration in quality, strength and value
