Typical build sequence for themed rockwork
01
Design
Forms, levels and colour references agreed from the concept or 3D design before work starts.
02
Armature

03
Shotcrete
Sprayed concrete built up over the mesh in layers to form the rock shell.

Carving
Texture, strata and cracks cut by hand while the surface is still workable.
