RAMMED EARTH

Because they are so similar in many ways (earth, formwork, appearance) I will go straight to:

RAMMED EARTH.

Sometimes known as Pise, this method is similar in construction to Poured Earth in that it uses formwork, but there the similarities end.

Where Poured Earth is a very wet mix put into forms, Rammed Earth is a DRY mix (sometimes slightly moistened). Successive layers of soil are put into the forms and tamped down, either by manually pounding the soil with a heavy bar, or using pneumatic tampers with a heavy end.
The soil is compacted until it "rings" - then you know it's just right, and so put the next layer in !!

One benefit of this system is that you can take the time to be more artistic, by adding contrasting layers for a finished effect that almost looks like a mural !!

Pise examples here in the harsh Australian climate have survived in wonderful condition for well over 100 years - not bad for tamped soil !!

So it is obviously durable, and with a little care, will outlast many modern homes. Given the thick (typically 30cm) walls, they are also wonderful spaces for living.....

Have a look at some modern-day examples.....

Once again the only limiting factor is one's imagination!! 

I have seen some beautiful buildings, even including industrial warehouses - it's great to see people embracing this method of construction.

See you soon !
