Ensure adequate access to the pour or discharge point for personnel and equipment for reaching difficult areas.
Wherever possible, use the transit mixer to discharge concrete directly into its final position. Avoid dropping the concrete from a height.
Start pouring from the corners/edges and move towards the center.
Don't allow the concrete to pile up in large heaps or sloping layers.
Place the concrete in a series of layers of equal depth - not more than 300 mm to 500 mm deep - only after the underlying layer is properly compacted.
