Reasons why you should use Interlocking Stabilised Soil Blocks in construction

From the UN Habitat, international organisations that support environment as well as bodies uniting construction engineers advocate the use of the carbon-saving Interlocking Stabilised Soil Block [ISSB] for construction as an alternative to the traditional fired brick, which is devastating Africa’s beautiful landscape.

The ISSB is a compressed block of moistened soil, mixed with a little cement, which is cured rather than fired.

  • Since the ISSB is not fired, no trees are chopped down to fuel brick kilns, making ISSB far more environmentally friendly. Ancient forests are preserved and C02 emissions drastically reduced.
  • ISSB is proven to be stronger than the conventional clay brick. Dry compressive strength testing at the University of Bath, UK, suggests ISSB is up to 80% stronger than a clay brick.
  • The interlocking feature of the ISSB means much less mortar is required between courses, construction is easier and costs further reduced.
  • ISSB is quicker to build with. ISSB blocks are also made on site, reducing costs further.

“ISSB demonstrates how environmentally-friendly construction technologies can be made more affordable to the poor.” UN Habitat


Not only ISSBs compressed earth technology environmentally sustainable, it is cheaper too! Research by a leading British quantity surveyor concludes that construction costs can be reduced by more than 50% using the ISSB. This is because the blocks are made on site and are uniformly shaped, while there is little mortar used between courses and much less need for plastering.

The award-winning company – Makiga Engineering Services Limited – has perfected the manufacturing of Interlocking Stabilised Soil Block pressing machines both manual and hydraulics. With a very affordable cost, they have supplied all over Africa: Kenya, Rwanda, Uganda, Tanzania, Burundi, Ghana, DRC Congo, Zambia, Mozambique, Malawi and the list still growing. These machines have transformed thousands lives financially by their use in building houses, schools, residential facilities for NGOs, water tanks, irrigation facilities, ovens, and so on.

‘By developing and promoting low-cost and sustainable construction technologies, [HYT] is contributing to the UN Habitat agenda of adequate shelter for all.’ Executive Director, UN Habitat.

Nevertheless, ISSB is stronger and more durable than the traditional fired brick. Experts at the world-renowned Bath University have tested the ISSB and found it to be many times stronger than local African bricks. ISSB is approved across African countries.
