The block is the whole point
Compressed to 1,000–1,900 PSI. Fireproof, insect-proof and beautiful. Here's every size we make, how to choose a type, and how to get them.
Block sizes
Every block can be made 2" to 4.5" thick (interlocking: 3" to 5"). The size you pick decides which machine makes it.
Stabilized or un-stabilized?
The single biggest decision after size. The short answer: if the wall will see rain, stabilize it.
Un-stabilized Pure earth
Natural earth only: clay, sand, aggregate and silt.
- Lowest cost, nothing added
- Goes on the wall straight from the machine, no curing
- Ideal clay content: 20–35%
- Must be protected from weather by deep porch roofs, or a lime, earthen, stucco or paint finish
Stabilized ~8% cement or lime
About 92% earth and 8% cement, lime or fly ash.
- Fully water resistant
- As strong as, and denser than, traditional masonry
- Ideal clay content: 15–25%, with more sand (cement bonds with sand)
- Needs to cure before laying. Works anywhere other masonry does, including basements
Our recommendation: use stabilized blocks. For most projects, stabilized is the safer choice. Use it for:
- Any exterior wall that will see rain, or that you want to leave exposed
- Foundations, stem walls, basements and anything touching the ground
- Outdoor kitchens, fire pits, garden walls and benches
- Humid or rainy climates, or any time you're not sure
Pure earth makes sense for interior walls, or exterior walls fully protected by deep porch roofs or a plaster finish. Many builders combine the two: AECT's Building Off The Grid home used 6,500 stabilized exterior blocks and 3,000 un-stabilized interior blocks.
