Reinforcement Placement

Before pouring concrete, reinforcement cages are positioned accurately within the formwork, following design specifications and ensuring proper cover and anchorage.

Concrete Pouring

The concrete is poured carefully to avoid displacing reinforcement or damaging the formwork. Vibrators are used to achieve compaction, and the process is controlled to prevent cold joints or segregation.

Formwork Removal

The removal process is critical to prevent damage:

• Timing: Based on concrete strength gain, curing conditions, and formwork type.
• Method: Sequential removal, starting with non-structural elements, followed by structural components.
• Inspection: Post-removal checks for cracks, deformation, or other defects.
