Compressed Earth Block Print E-mail

Background:

  • The first compressed earth block press was a manual press and was developed in Colombia in 1956.
  • Bricks can be made on site using local earth with a small addition of cement or lime stabilizer.
  • The soil is highly compressed using hydraulic pressure, resulting in a very dense stabilized earth brick.

Benefits:

  • Avoids wastage with packaging (Saves landfill costs).
  • Costs 20% less than a conventional brick.
  • 80% of the cost of the bricks goes toward creating work onsite.
  • Durability - Stabilized bricks can be used as face bricks.

Technical information:

  • Building blocks made of clay soils with 3-5% of lime or cement stabilizer.
  • The mixture is then mixed with a minimal amount of water and then compressed using a Hydraulic press.
  • The bricks are then cured before use.
  • Bricks can be used for dome & vault construction (Avoiding use of conventional structural materials for roofs)
  • Attachments can be purchased to manufacture different shaped brick as well as various roof-tiles.

Company track record and examples of work:

  • Alliance Francaise Cultural Centre – Cape Town, 1997 (Project Architect for ACG Architects)
