Trenchless Pipe Lining in Toronto

Signs you need trenchless pipe lining

• Roots enter at many clay joints, but the pipe itself is still round and in line
• Cracks or pinholes in cast iron that still holds its shape
• The lateral runs under a mature tree, a front porch, a driveway or a garden you want to keep
• You want to stop root intrusion permanently without digging

What causes it in older Toronto homes

Toronto’s older streets are full of big maples, oaks and chestnuts planted along clay sewer routes. Their roots find every open joint. On many lots the lateral also runs beneath a front porch, a shared driveway on a semi, or stone steps. Digging there means demolition and rebuilding, which is exactly what lining avoids.

What we do on site, in order

1. Camera inspection to confirm the pipe is a candidate: lining needs a continuous host pipe, and it cannot fix a collapse or a major sag.
2. Thorough cleaning, usually with a jetter and a root cutter, so the liner bonds to clean walls.
3. The liner is wetted out with resin, inverted or pulled into place from a cleanout or small pit, and cured.
4. Any branch connections are reopened with a robotic cutter from inside.
5. A final camera run shows the finished pipe.

What affects the price

Length of the run, pipe diameter, the number of bends and branches, and how much cleaning is needed first all affect the quote. Lining can cost more per metre than open digging, but it often comes out cheaper once you count replacing a driveway, a porch or a tree. We give you both options when both are possible.

When to call right away

If you already have a backup, call to get it cleared first. Lining is planned work; it is done once the line is open, cleaned and inspected.
