Since most of us have not had experience building form work for concrete pours, there was a lot to learn. One important thing we found out during the process is that well built form work is the KEY to success in any concrete pour.
Concrete is heavy, weighing about 150 pounds per cubic foot. That means anything that wet concrete gets poured into, needs to be able to withstand that weight and not blow out on the sides. We used melamine board, really what you might find on a counter top, to form sides. These were screwed together with MANY screws and surrounded with two by fours. Inside, blocks of wood were placed to create the negative spaces.
Overall, ten forms were made and they took about two days from start to finish. Our team mate Hawraa was our key quality check monitor, nothing went out the door without her approval.
