fabric concrete formwork saves money, material and transportation costs. this type of formwork is the first advancements in concrete formwork since WWII when plywood was invented and is changing how things are being built. these formworks are being shipped in bookbags and are up to 300 times lighter. these woven geotextile fabrics allow air bubbles and excess mix water to seep out making the concrete more sustainable. mark west goes into great detail in this advancement at this website http://www.umanitoba.ca/faculties/architecture/cast/pdf_downloads/1_pr.pdf
i started rapidly seaching the library and internet to find as many examples as i could. i began to search for geotextile fabrics to buy because i wanted to make something too. with lack of money and materials i had to improvise, the rim of a fastfood cup, a plastic bag and some cardboard is what i came up with. the biggest amazement to me was that the bag did not break. when i was inspired to make my plastic bag concrete formwork that would end up in a swollen column i was looking at these websites http://www.umanitoba.ca/faculties/architecture/cast/pdf_downloads/4_pr.pdf
