Rubber Culvert Balloon With Super Expansion, Anti-Aging, Reusable
Black inflatable culvert rubber balloons with rectangle shape section.
Rubber Culvert Balloon adopt high-strength synthetic fiber fabrics as pressure-resistant skeleton, and the adhesive protective layer is made of vulcanized synthetic rubber. As a manufacturer, we provide culvert rubber balloons with various sizes and shapes depending on the size of the bridge, gutter, tunnel and other constructions.
Before the construction of hollow components, put the designed culvert rubber balloons coated with release agent on the location and filled with compressed air. It can shrink up or fold flexible when not in use, and reuse in the next project.
