Pouring Fundamentals
1. When pumping concrete do not aim it at an ICF form, the pressure could damage the block.
2. Allow concrete to fall straight down until it begins to build up a mass of concrete.
3. When pumping, push the concrete flow at a 45-degree angle so it flows smoothly in the direction you are moving. Let the concrete flow naturally.
4. Work closely with the pump operator to pour smoothly. Good communication is critical.
5. Utilize a restrictor end (such as a Double L nozzle) on your boom hose with a 3” max end size to reduce concrete surge.
6. Discuss this with your pumper when ordering your pump.
a. BuildBlock recommends boom pumps for full wall pours.
b. Work in a continual direction, remembering that a concrete pour typically finishes where it begins.
