The forms for the stem walls were set on the previously placed continuous footing. The top surface of the footing had been damaged by freezing. Based on spot checking the entire perimeter of the footing, I conclude that about 50% of the area to receive the stem wall has surface damage extending about !:I" to ~" deep. This amount of damage will not impair the intended performance of the footing to carry the loads of the residence to be constructed. However, this damaged surface material will prevent adequate unity from occurring between the stem wall and the footing. As an alternate to removing the forms and cleaning the entire footing, installation of one continuous #4 reinforcing bar throughout the full length of the bottom of the stem wall will provide structural continuity. This bar needs to be set at about 2" above the top of the existing footing. At the same time, I observed the condition of the pier pads for interior supports. These pads have. freeze damage, especially at the top corners. As long as posts are placed near the center of these pads, they should perform adequately as load carrying footings. Donald C.
