Firma Tech is a company based at Macleans Ridges, New South Wales.

They don't have a web presence as yet, but as you can see from the photos below, they appear to make a good product, though I haven't actually seen any of their bricks.

If you contact these people, can you please tell them you found them on the Rammed Earth website.
