Abstract: A method of constructing a section of an elongated dike comprises the following steps: First, an uninflated tube is positioned along an axis. Second, a strap is positioned at a first end along a second axis. Third, the strap is disposed subjacent to the first tube. The portion of the strap extending from the first tube defines a free portion of the strap. Fourth, the first tube is inflated with liquid. Fifth, a second tube is positioned parallel to and along side the first tube, opposite the first end of the strap. Sixth, the free portion of the strap Is disposed over the top of, down and subjacent the second tube and disposed over the top of the first tube. Seventh, the free portion of the strap is loosely coupled with a first buckle. Eighth, the second tube is inflated. Finally, the strap is tightened to secure the tubes together.
