7 Tips for a Successful Vertical Concrete Placement

Planning and communication will help you achieve a successful concrete wall pour.

Planning cannot be overemphasized. Attention to detail is critical and the key personnel must be aware of the formwork tolerances, finish surface quality requirements, and proper placement and vibration procedures. A thorough plan can help ensure success of any wall.

  1. Ensure the mix design has been submitted, approved and ordered
  2. Finalize the means of placement — conventional pumping, placing boom or bucket
  3. Concrete superintendent plans the placing rate, which will determine truck spacing; vibrator type, either external, internal or a combination of both; and placement access/pour platforms and testing/cleanup areas.
  4. Concrete superintendent reviews grades with the formwork superintendent
  5. Concrete superintendent reviews locations of all blockouts and embeds that will block the flow of concrete from above — this is critical as these locations will result in rock pockets/consolidation issues if the placing crew is not aware of them. A placing sequence should be discussed in advance of form close up, considering these restrictions.
  6. Ensure the team is clear about who has authority to reject concrete and for what reasons.
  7. Have adequate, dedicated power for vibrators on critical pours and ensure backup power readily available.
