Culvert Balloon 900mm×16m

A culvert balloon (also called an inflatable pipe plug) is a durable, air-filled rubber device used to temporarily block or seal culverts, drainage pipes, or sewer lines during maintenance, repair, or testing. It expands when inflated to fit tightly inside the pipe, preventing water or debris flow, and is easy to install and remove. They are commonly used in construction, plumbing, and civil engineering works.
