Culvert rubber balloon for concrete pipe
Rubber inflatable 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.
Rubber Culvert Balloon With Super Expansion, Anti-Aging, Reusable
Rubber balloon for culvert formworks is a kind of cylinder bag that can expand, shrink, used to form concrete component of cavity. It is easy to be used, convenient and durable, is soft and can fold, curly, contraction when it isn’t inflate, it have the enough strength to withstand the pressure of concrete when it is inflated, this is incomparable with any traditional template, it is used in reinforced concrete members, including stake roof, roof board column, beam, building, water conservancy project (shipyards slipway, dock).
