The tree is made with Ferro cement or Ferro concrete where the desired shape may be built from a multi-layered construction of steel mesh, supported by an armature, or grid, built with reinforcing bar and tied with wire. For optimum performance, steel should be rust-treated, (galvanized) or stainless steel. Over this finished framework, an appropriate mixture (grout or mortar) of Portland cement, sand and water and/or admixtures is applied to penetrate the mesh.
