On the left of the photo above, Steve, foreman, DR Contracting, Surrey, BC, stands beside a column poured in the rain with Fast-Tube™. On the right, a contractor tries to protect his cardboard tubes from the rain with polyethylene.
"Forming with cardboard in the rain leads to failure", said Dan, President of DR Contracting. "With Fast-Tube™ we set up any time and never worry about the weather."
Cardboard is hydroscopic, weakened by moisture and rain, and can lead to column form failure when exposed to moisture. Fast-Tube, made of polyethylene, is uneffected by moisture, and can be left out in moisture and rain indefinitely.
