What happens here
After digging the holes, cardboard Sonotube forms are inserted. These forms are cut to the appropriate length, ensuring they extend above the ground level. A bag of drainage rock is poured into the bottom of each Sonotube. This rock layer is crucial for preventing water from pooling at the base of the concrete footing, which could lead to heaving during freezing temperatures.
Goal: Cardboard Sonotube forms are cut to length and placed into the footing holes, with drainage rock added at the bottom to prevent water accumulation.
