CIPP / Gravity Pipe Relining
Trenchless pipe repair that forms a new pipe inside the old one for suitable sewer and gravity drainage lines.
The Problem We Solve
Traditional pipe replacement often requires breaking floors, excavating driveways, damaging landscaping and disrupting buildings. For many drains and sewer lines, the problem is inside the pipe: cracks, leaking joints, root intrusion, corrosion, holes or localised structural defects.
HydroTrace Solution
CIPP stands for cured-in-place pipe. A resin-saturated liner is installed into the existing pipe and cured so it forms a new internal pipe. The host pipe remains in place while the new liner seals defects and restores flow. This is a trenchless or minimal-dig method when the pipe is suitable.
Our Step-By-Step Process
- Inspect the pipe with CCTV to confirm condition and suitability.
- Clean and prepare the pipe using jetting or mechanical cleaning.
- Measure the pipe and prepare the liner according to the repair length.
- Install the liner into the host pipe and position it correctly.
- Cure the liner and complete a post-installation inspection.
Why This Matters
- No-dig or minimal-dig repair
- Less disruption to floors, paving and landscaping
- Seals cracks and leaking joints
- Helps prevent root intrusion
- Strong long-term rehabilitation option
Best For
- Sewer pipes
- Gravity drains

- Recurring root-damaged lines
CIPP / Gravity Pipe Relining FAQs
Is every pipe suitable for CIPP relining?
No. CCTV inspection is required first. Severe collapse, poor access or major deformation may need alternative repair methods.
Does relining reduce pipe size?
The liner creates a new internal surface, so there is a small diameter reduction. In many cases improved flow and smoothness offset this.
Do you inspect after relining?
Yes. A post-installation CCTV inspection is recommended to confirm the repair quality.
