Hydro-Excavation to expose and replace sewer line
under historic building
The Problem: An old clay sewer line that ran beneath
a local tavern required replacement. Access to this line was very
difficult because there was no basement or even a crawl space under
this rear section of the historic building. This pipe needed to
be exposed, while at the same time a tunnel needed to be dug to
allow for replacement with updated PVC pipe. Hand digging this approx.
40ft section would be painstakingly slow and dangerous.
The Flex Services Solution: In less than a day,
this job was safely completed with our hydro-excavator. Because
we can excavate through small diameter hoses, we could attack the
tunnel from both outside the building but also from inside the basement
– setting up our hose through a small basement window. Working
in from both sides with our water spade plus extension wands, the
cracked sewer line was exposed and a tunnel created to allow for
a new pipe to be installed.
