Compressed Earth Block Machines

Looking for an “Eco-Friendly” building method?

The problem is that you might:

1) Become overwhelmed with all of the eco-building options that are available and don’t know where to start.

2) Discover after a little bit of research, that many supposedly eco-friendly building methods aren’t very environmentally friendly at all.

Environmental impacts are hidden or glossed over. These include transportation costs (e.g. importing materials all the way from China) and damaging production methods (e.g. massive heating requirements in traditional brick making). In fact, some eco-friendly solutions may be less than 30% environmentally friendly.

Whereas other methods have different drawbacks. A good example of this is earthbags which are environmentally friendly, but they’re also very slow, labor intensive and just plain inefficient.

Our solution to your problems

You need something that is environmentally friendly and locally produced.

You need something that is strong, durable, weather resistant.

You need something that is easy to build and will last you a lifetime.

You need something that is fast, mechanised and automated.

You need all of this affordably priced.

Components

  • A Hopper this is where you fill in the dirt. Made from welded steel, 6 feet wide – it has a large handling capacity.
  • Grate. This prevents large objects such as stones from falling into the compression chamber. It’s placed at the bottom of the hopper, above the compression chamber.
  • Shaker this vibrates the hopper so that any loose earth will shift into the compression chamber.
  • The Compression Chamber is a metal box with a nylon liner on the inside which helps to give the bricks a smoother finish. This is where hydraulic pressure is applied to the soil.
  • Hydraulic Cylinders – these are the components that do all of the action. They apply high amounts of pressure which shapes the earth and are also easy to detach from the machine for disassembly. They are made up of:
    • The main cylinder moves up and down and compresses the earth bricks.
    • The soil drawer ejects the bricks from the machine and also loads the soil into the chamber.
  • The Frame holds everything together and is easy to disassemble and arrange once constructed.
  • Tractor mount, this is where the hydraulic cylinders can be attached.
  • Pressure gauge, by looking at this you can gauge how much pressure is being applied and thus, how dense the brick will become.
  • Controller Box used for setting the timings and controls for the machine.

Comparisons

Our research looked at machines of comparable quality. They had to be automatic and produce CEBs at similar rates to our own machine. We found the average price point was £25,000. What’s more, none of these were sold in the UK, they were only sold in America!

We decided that it doesn’t environmental sense to use a machine which is built on the other side of the planet. However, we still wanted a benchmark by which we could out compete the competition. So that’s why we made a machine that was not only comparable in quality to our distant rivals, but was also of better value.


What we offer

  • You can buy one of our CEB press machines
  • You can hire one of our CEB press machines to use yourself
  • You can hire us for one of our services
  • You can even build a CEB press machine yourself (and we’ll train you up)

However, all of this might confuse you. The best thing to do is to contact us, let us know what it is you need and what you’re intending to do. Then we’ll be able to help you in the best way we can.
