      • Fixings: As recommended by container manufacturer.
          - Individual ties of lacing wire: Do not use.
      • Assembly:
          - Starting from top corner join edges of adjacent panels together in a continuous
             operation.
          - Join to adjacent units, above, below and on all sides.
          - Provide all internal bracing, pre-tension mesh.
      • Installation:
          - Vertical joints: Staggered in adjacent courses.
          - Lifting and placing of prefilled units: Use lifting frames and remove on
             completion.
          - Stepped constructions: Align bottom edge wire of upper baskets with a
             longitudinal wire of mesh of lower baskets. Provide continuous lacing along all
             horizontal joints at front and rear of wall.
      • Filling:
          - Maintain shape of basket during filling.
          - Fill to full height in sequence recommended by manufacturer.
          - Top mesh: To bear upon fill.
