Basic Concrete Forms
Poured wall concrete forms come in a wide variety of different forming systems. Over the years I have become familiar with several types, some of which worked very well, others not so well.
Perhaps you remember the old Johnny Clamp system, this was my first experience with wall forms. These forms are made with four by eight sheets of 3/4 inch plywood and two by fours, talk about heavy. Anyone who has ever used the old Johnny Clamps really appreciates the newer styles of forms.
Modern concrete wall forming systems are designed to sit on a footing that is flat, level, smooth, and square. The footing is the key to getting a poured concrete wall that is straight, level, and square.
If you do a good job on the footings the easier the setting of the wall forms will be. All modern forming systems are designed with speed and accuracy in mind. An efficient wall crew can form and pour a full basement on a 2,000 square foot ranch in a single day with good organization and support equipment.
