COMPRESSED STABILISED MUD BLOCKS
CSEB are a mix of soil, sand and 5% of cement.
• They are compressed manually. So they don’t require energy.
• They are not fired!
• They are used for masonry of walls and columns, as any conventional brick.
• They can also be used for building arches, vaults and domes.
• They have been used up to 4 floors (load bearing walls).
