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.

Abstract: A liquid filled dike is described. The dike is formed of a flexible material selected to contain water. The dike includes at least two bladders which extend at least a portion of the length of the dike. The dike can be transported in empty condition and filled on site. When it is no longer required at a particular site, the dike can be emptied and stored for later use. The dike is self-leveling and may include a leak detection system.
