  • Test Block First

    Never skip test blocks — wrong soil mix cracks walls after form removal.

  • Lift Height

    Keep lifts at 100–150 mm — thicker layers compact unevenly and leave laminations.

  • Fire Safety

    Keep a fire extinguisher within arm's reach when working with heat, sparks, or flammable materials.
