Begin pouring
To start with, mix enough concrete to build around 20-40mm of your wall. Shovel it into the formwork, and vibrate it into the corners. As you go, inspect the outer side of your formwork for concrete attempting to come out the bottom. Mix and pour slowly, while inspecting the bottom of your form as you go until you get to around 150mm above ground level. At this point you have cleared the first major hurdle. Let the concrete that you have already poured set for 90 minutes, as this will allow it to support the weight of subsequent pours, without as much risk of a blowout.
