CIEBs are made from laterite soil mixed with a small amount of cement (5–10%) and compressed in a hydraulic press. The blocks interlock like puzzle pieces, reducing the need for mortar and creating stronger walls.
Switching to CIEBs: What Homeowners Need to Know
Compressed Interlocking Earth Blocks (CIEBs) are gaining attention in The Gambia as a sustainable alternative to cement blocks. For homeowners thinking about building with CIEBs, understanding the process, costs, and benefits is essential before making the switch.
What Are CIEBs?
Benefits Over Cement Blocks
- Lower cost in the long run: Reduced cement use and less need for plastering.
- Better indoor climate: Earth walls stay cooler and reduce humidity.
- Eco-friendly: Smaller carbon footprint compared to cement.
- Durability: Less prone to cracks, dampness, and mould when properly built.
The Building Process
- Site soil testing ensures the right mix.
- Block production is done on-site or nearby, cutting transport costs.
- Walls are stacked with interlocking joints, reducing cement use.
- Finishes may include plaster or lime render, but in many cases walls can be left bare.
Cost Considerations
While the upfront cost of producing CIEBs can be slightly higher than buying cheap cement blocks, the savings on plaster, paint, and long-term maintenance make them more economical overall.
What Homeowners Should Ask Builders
- Has the builder worked with CIEBs before?
- How long are the blocks cured before use?
- What finishes are recommended for durability?

Takeaway
Switching to CIEBs is not just a construction choice—it’s an investment in healthier, more durable, and more sustainable housing for Gambian families.
