Tree Root Infiltration

What Does Tree Root Infiltration Mean?

Tree root infiltration is defined as the presence of tree roots in underground water or wastewater piping. Tree roots seek out the best sources of moisture and are naturally attracted to water vapor emanating from underground piping systems.

Roots will typically enter pipes via the most vulnerable locations, which include cracks or loose pipe joints.


Trenchlesspedia Explains Tree Root Infiltration

Older clay pipes are more susceptible to tree root infiltration since they are more prone to cracking due to soil settlement and loose joints from broken down gaskets.

Once inside the piping, tree roots will grow and multiply in a tangle and can result in clogging. As the home plumbing system continues to be in operation, grease, paper and other objects can get trapped within the roots and exacerbate these problems.

If left untreated, roots will continue to grow and multiply, applying considerable pressure on the inner walls of the piping until the pipe ruptures. Tree root infiltration can be remedied by several methods including:

  • Cured-in-Place Piping (CIPP) – This method involves lining the inner walls of the pipe with a resin saturated jointless tube. This epoxy resin binds the tube with the existing pipe and prevents further root infiltration.
  • Hydro jetting – Hydro jetting uses high-speed water under pressure to remove all roots and other debris inside piping.
