How The World Does Rammed Earth Nk’Mip Desert Cultural Centre in the South Okanagan Valley in Osoyoos, British Columbia, Canada. Successive layers of differently colored local soils were placed into the 600mm wide formwork and a pneumatically powered tamper was used to compress each layer to about 50 percent of its untamped height. The technique results in a physically strong, durable wall with excellent thermal qualities, heating up slowly during the day and releasing heat in the cool evenings.

The Basics of Rammed Earth Building Rammed Earth building, also known as taipa (Portuguese), tapial (Spanish), and pisé (de terre) (French), has been in use for millennia, the earliest surviving examples from 5000 BC in China.* Formerly time-consuming yet dirt cheap, today the technique can be as costly as stone in the hands of certain architects. For some big projects soils have been imported, large quanities of cement and insulation have been incorporated, and the expense of elaborate frame work and machinery can be sky high. Yet, if you have a nice 30% clay/70% sand soil on your building lot (or chalk, lime and gravel) and are good at constructing simple frames (or have access to prefabricated formwork), rammed earth building can be one of the most inexpensive and sustainable building methods on the planet. Whereas trees are being cut down by the thousands-of-acres-a-day, and cement is polluting to manufacture, soil is abundant and the earthiest of earth friendly. Rammed Earth Walls This termite-resistant, non-toxic, fireproof technique is also good to build walls, benches, supports, columns and thick blocks which can then be layered like bricks with a mud slurry between. Rammed earth using rebar, wood or bamboo reinforcement should be employed in earthquake prone areas. Although rammed earth has tremendous thermal mass and holds and releases heat slowly, it is not a good insulator. For colder climates, rammed earth walls can be insulated with a panel of recycled styrofoam. Rammed earth keeps interior humidity between 40 and 60 percent where walls containing clay are exposed to an internal space, the ideal range for asthma sufferers and for the storage of susceptible items such as books and artwork. How Long Rammed Earth Building Takes The process is time consuming and repetitious, but rewarding. And now with power tampers, the job is a bit less demanding. A newly tamped section of wall is so solid that, if desired, the forms can be removed immediately. If wire-brushing is needed after the forms are removed, to even out the framework edge imprints or to add texture, it must be done in the first hour after the form is removed, for the wall dries to the touch quickly, yet will not be fully dried throughout for months. Exposed walls may need to be sealed to prevent water damage if the walls will be exposed to heavy rain. A Popular Form Of Building, Still Worldwide, more than forty percent of the population live in earth built structures, yet earth building disappeared in western countries after World War II, when suburbs sprung up and speed reigned. The skill was lost. Although never given up in developing countries, the west now is relearning this ancient art and begging building authorities to allow them to build in this very natural technique. Let’s hope the building regulators allow this building method to take its rightful place of prominence. We need to step back and learn from the past, but with pneumatic tamper in hand and openness of mind.

Now, after looking at all this wonderful information. Mmmmmmmmmm, now I am having a hard time making a decision between adobe and ram earth. My opinion of ram earth, changed completely. The view I had of it, was not as beautiful as adobe homes, or cal-earth dome homes. I will probably start the construction next year. The site is 60Km. from sea, and very high humidity, around 95%. Any comments welcomed. THANK YOU SO very MUCH!!!!!!! DD Reply The last photo is not Indian, it is written in Persian (Farsi). Besides, the Indian alphabets are not anything near Persian alphabets I’m not sure who first decide that this is in Indian but I assume it would be only scientifically right to correct the information given in this page. In the above it is written: two person named tabarkonandegan (as earth stocking mans) then from two stock of soil, make a wall… By the way thank you for the information you provided here.
