About Compressed Earth Bricks
Compressed earth bricks (CEB) or compressed stabilised earth bricks (CSEB), also known as compressed earth blocks are solid earth bricks made from the subsoils, which is processed and pressed at optimum moisture content and at high pressure in a specialised machine. CEB rely on this high pressure to create a permanent tight bond of the soil particles, therefore, we end up with a very solid, dense brick that can be handled and stacked immediately. The density achieved is highly desirable when building with earth and has many advantages in the overall performance. Modern technologies and science have taken this ancient building material to a whole new level in performance and accessibility whilst being very affordable.
CEB and CSEB are an alternative to mud bricks and in single to double story buildings, an alternative to clay fired bricks also. CEB share all the same benefits of the classic mud brick, whilst our CSEB can be made as durable as medium quality fired bricks in terms of durability and weatherability. CEB are not baked like regular bricks and it is said they use just 10% of the energy needed to manufacture in comparison to fired bricks.
Availability of raw material
There is reported to be billions of tonnes of suitable overburden subsoil costing quarry companies millions of dollars and an unimaginable amount of energy to deal with, it literally is a “burden” to them. In many quarries, it is said that this overburden gets handled multiple times to access the rock benefit and costs them on average $2.50 per cubic meter to move each time. There is literally enough to build cities made from this overburden. Potentially, earth can become a serious contender amongst mainstream masonry construction in Australia.
Our current supply of earth comes from a quarry as mentioned above and would appear infinite in supply as there is a whole mountain of this sandstone coloured subsoil needing to be moved to access the rock beneath. The raw material costs for producing a brick are basically the cost of trucking the soil to the factory, hence our low cost per unit price.
About our bricks
CEBA’s earth masonry units are engineered and intended to be used to construct load-bearing walls (Full Masonry construction). Designing houses or any structure with load-bearing CEB has significant advantages, one of which is it cuts out a lot of the material and labour costs. For example, current buildings require a wooden frame, external cladding, insulation, plastering, and painting. Whereas a CEB walling system includes all these steps in one whilst being simple, low cost, non-toxic, DIY and environmentally friendly.
In terms of engineering and design, a lot of the standards for CSEB are adopted from mainstream masonry construction and are recommended to be treated as Full Masonry construction.
In terms of bang for ya buck, our bricks sit very well in comparison to other masonry products. For example, in comparison to the cheapest fired face brick ‘Everyday Life’ offered by Austral Bricks. AB-Bricks Price List NSW PDF
- Austral Bricks per m2 of wall (face wall) $86.88
- Austral Bricks per m3 (volume) $785.20
- Austral Bricks unit price $1.51
There are 4.7 standard fired bricks to one CEB by volume
- CEBAs CSEB per m2 of wall (face wall) $89.60
- CEBAs CSEB per m3 (volume) $353.34
- CEBAs CSEB unit price by volume comparison $0.32
Labour costs have many variables on both sides, however, consider a brick veneer still needs stick framing, insulation, plastering, and painting. In terms of material costs alone with our earth bricks, you are basically getting a triple brick home cheaper than the cheapest brick veneer home. Minus the above-mentioned materials associated with brick veneer and still, we haven’t yet considered the saving in the running costs that a well-designed earth home naturally inherits.
We supply bricks all year round with a current capacity to produce up to 1200 bricks a day. We keep a stock of our standard size (105mmH) ‘Sandstone’ bricks in stock usually available immediately. However to avoid delays we recommend ordering 28 days in advance. Custom sizes please allow 6 weeks for your bricks to arrive on site from date of order.
