I saw this on Facebook where someone said stabilizers aren’t necessary. That is usually the case. Compacted subsoil in earthbags covered with plaster is the norm. But there may be situations where stabilizers are beneficial such as in extremely wet areas. There’s even the possibility of making an earthbag stone wall without plaster using this type of construction. There’s also the option of spraying it on walls to create stone PISE. Let us know if you try this out.
