New black polyethylene pipe with welded joints in the trench

What needed doing

The buried sewer pipe was damaged and needed relaying.

What we did

We dug along the route, partly with a mini excavator, and removed the broken old sections.

In their place we laid polyethylene (PE) pipe joined by welding, with bends and junctions for the connections.

The result

The drain has a new polyethylene pipe, with welded joints instead of the broken ones.
