Fill earthsacks and tubestock with mixture of 95% sifted subsoil to 5% cement. Lay wall in desired shape.
Tamp bags hard and flat as they are lain, and tuck in any loose corners.
In wheelbarrow mix 3 parts sand to 1 part cement and 1 part sifted clay. Add water to make VERY wet slurry. Keep adding water as bags move through.
Dip pre-moistened burlap squares and apply to wall, shingling in lower sections below top of wall.
Stiffen remaining slurry mix with additional sand and apply to top of wall and any thin areas.
A whitewash or clay-lime render can be applied as a finish coat.
