A method and system for installing an insulated concrete wall includes insulation panels placed in an upright manner. Generally T-shaped wall studs are placed next to the insulation panels such that the front section of the wall stud is on the outside of the insulation panels and an anchoring section of the wall stud extends beyond the insulation panels into the gap into which concrete will later be poured. Concrete pouring forms are placed so as to render the gap into which concrete will be poured a desired thickness. The wall stud may also include slots for receiving cross-ties that secure the concrete pouring forms in proper position and retaining nubs that prevent the insulation panels from floating when concrete is poured. Concrete is then poured into the gap, surrounding the anchoring section the T-shaped wall stud.

The current invention discloses moisture resistant column forms constructed from corrugated plastic. The forms disclosed herein are lightweight and can be easily assembled at a construction site or remote location. The forms can be positioned over pre-placed sections of reinforcing bars, or sections of reinforcing bars can be placed into a form once it is in position. The forms disclosed in the current invention can be easily removed, but they do not attract insects and therefore do not have to be removed from columns after the concrete has dried. The forms disclosed herein have generally square perimeters when they are assembled and put in place, but after concrete is poured into the form, the side walls will undergo uniform deformation/displacement due to the hydrostatic pressure of the concrete and the resulting column will have a generally circular perimeter. A method of using the forms is also disclosed.
