- Alan discusses how BioBuild approached building a rammed-earth feature wall in an office location in Auckland. Hear about the recipe for a strong and beautiful earth wall, the process for mixing and placing the mix, and the ramming activity.
This video is a long one - but well worth the wait to see the team at work throughout the process!
That rammed earth wall will look so much nicer than any other finish in that building. A real work of art.
Beautiful rammed earth, great work. If l may ask where can l purchase that electric compactor or whats the real name of that tool being used to ram the earth?
Great work
God's glory
This is beautiful. Would it be possible to add a layer of thin crushed shell or pearl oyster for shine? Also, if I wanted a lighter finish could I use light coloured earth or perhaps add pigment?
What was that spray at the end?
You used a makita electric compacter, I was unable to find that, all I found was cement vibration tools. Do you have a model number? If you did not have to carry tools up to that floor by hand you said you would have used another tool, which one?
It looks like a regular hammer drill on just set on hammer mode, not drill. Never thought of using one.
What is the ratio of cement, mud and sand.please tall me the actual percentage of that's elements
Pretty sure he said 10% cement
@@scroogemcduck1462 mud??sand??
@@donthateoneself6884 There are 100s of videos on this if you just search for rammed earth. You want to shoot for around 25% clay and the rest being sand and small gravel

i can see that this wall is in a second floor...is that right? and this wall can be designed between 2 columns?
If the columns are strong enough to resist the forces of the ramming, then yes, it can.
I wonder that all that cute excellent layer go off when you need to cover the wall or painting isnt it?
How do protect the outer layer from water etc
@@alienergy5347 In this case it is indoor, so no rain washing or wind erosion. In an outdoor environment we would test the mix to see how it fares against the weather. Usually a small amount of cement is used in outdoor installations to increase the resistance, but even un-stabilised rammed earth can last for decades longer without cement.
My god father…..all that time and energy. Why not just lift panels into place. Earth Structures Group also offer prefabricated panels that are approx 50mm thick. That must have cost a small fortune in labour. I do admire the tenacity though.
Bringing sandstone from Uruguay probably negates the ecological aspect of rammed earth, it's a pity.
The milled sandstone comes from Muriwai, which is less than 40 km by road to Auckland. I think maybe you misheard the video :-)
