Sliplining and Pipe Insertion, explained.
Sliplining is one of the oldest trenchless methods. A new pipe, smaller in diameter than the host pipe, is pushed or pulled through the old one from an access pit. The space between the two pipes is then filled with grout so the new pipe is supported and the old one is sealed.
Because the new pipe is smaller, flow capacity drops somewhat, so sliplining suits large-diameter pipes with capacity to spare, such as big culverts and storm drains. For small residential laterals, lining with CIPP is usually the better tool. We use sliplining where it fits and explain the trade-offs honestly.
Signs this service fits
- A large storm pipe or culvert is failing
- The old pipe has room to spare for a smaller liner pipe
- A straight run with sound access at one end
- CIPP is not the best fit by size or condition
A good fit, and what to know.
We would rather you hear the limits from us than discover them later.
A good fit when
- Large-diameter storm pipes and culverts
- Straight runs with good end access
- Pipes where grout-filled insertion is a good structural answer
Worth knowing
- Small residential pipes are usually better served by CIPP
- Heavily bent runs may need another method

Does sliplining reduce flow?
Yes, because the new pipe is smaller. That is why it suits large pipes with spare capacity, and why CIPP is better for small laterals.
Can it go around bends?
Sliplining works best on straight runs. Bends limit pipe sections and may need extra pits.
Is the old pipe removed?
No. It stays in place and the gap is grouted.
