Expand buried pipelines without a trench

One of the most unique elements of pipe bursting as a rehabilitation technique is its ability for inline expansion without removal or excavation - or upsizing a pipe while it is being replaced. With pipe bursting, an expander head is hydraulically guided through an existing pipe, breaking it and allowing for a new, larger pipe to get pulled into its place. If desired, an expander then increases the space outside of the fragmented pipe before a new pipe is immediately pulled into place. We've been using pipe bursting for decades on iron, steel or lined pipes.
