Pre concrete pour inspections - Column

Verify Column Stability: Ensure that the column is stable and can support the loads during the repair process. Temporary supports or shoring may be required.

Check for Additional Damage: Inspect the column for any additional cracks, corrosion, or structural issues that may need to be addressed before reinstating the concrete.

Remove Loose Material - Ensure all loose, cracked, or delaminated concrete is fully removed from the surface

Clean and check Surface: Clean the exposed surface of the column to remove dust, debris, and any contaminants like oil or grease that could prevent proper bonding.

Examine Existing Reinforcement: Check the condition of the existing steel reinforcement. Look for signs of corrosion or damage.

Reinforcement Treatment: If corrosion is present, clean and treat the reinforcement bars with appropriate anti-corrosion measures (e.g., applying a protective coating).

Install Additional Reinforcement: If required, place additional reinforcement bars or ties according to the design specifications.

Check Formwork: Ensure that the formwork is correctly installed, properly aligned, and securely anchored. The formwork should be leak-proof and capable of withstanding the pressure from the fresh concrete

Release Agent Application: Apply a release agent to the formwork to prevent it from sticking to the concrete after curing.

Verify Mix Design: Ensure the concrete mix design meets the required specifications, including the proper strength, workability, and durability characteristics.

Check Concrete Temperature: If applicable, ensure the concrete is at the correct temperature, particularly in hot or cold weather conditions, to avoid thermal cracking or improper curing.

Final Inspection: Before pouring, conduct a thorough final inspection to ensure all the above checks have been completed satisfactorily.
