Doors and Windows

The same technique should be used around door and window openings. When pouring around windows, pour a small amount of concrete on either side of the window opening. Building up this small mass on either side prevents too much concrete from building up on one side of the opening and pushing the opening out of plumb or level. Flow concrete towards the opening instead of aiming directly at bucking. You can also pour and consolidate through the inspection ports in bucking on the bottom sill of windows.
