Pouring with a Plan
When pouring concrete into an ICF wall, it is not advisable to simply pick a spot and start pouring.
BuildBlock recommends that you find a starting location, usually a corner, and work in a continual direction around the structure. Don’t aim concrete directly at the ICF forms. Instead, let concrete flow straight down and build up a mass. Let the concrete flow naturally and push it at a 45-degree angle so that it flows smoothly in the direction you are moving. Never aim directly into the corner allow the concrete to flow into the corner and move to the other side of the corner quickly to continue pouring.
Vibrate each lift into the previous lift immediately using the fast-in, slow-out method.
