Use 5" slump concrete for the footing and first block.
Begin placement under openings and stepped footings to allow these areas to go 'off' first.
Use a pencil vibrator to consolidate footing. Do not over vibrate as this will force any concrete in wall to 'blow-up" the footing bag.
Fill footing in direction of fabric overlap (counter clockwise) to prevent concrete leaking between overlap.
IMPORTANT: Allow sufficient time for the footing concrete to go 'off' so that subsequent lifts do not increase hydraulic load in fabric. Kick the bag, or 'sound the concrete' to confirm stiffness.
Never use a retarder in the footing concrete. In winter, use a 2-1/2" slump mix and add a plasticizer to achieve flow. Continue filling wall when the slump has returned to 2-1/2".
Check wall alignment against string lines during the pour.
