Pre-Relining Inspection
Pre-Relining Inspection
Relining quotes should start with footage. Without an interior inspection, no one can honestly say whether a line can be lined, or whether it should be replaced.
Symptoms we're called for
- A relining quote with no inspection footage
- Conflicting advice about lining versus replacement
- A line with known roots, offsets or collapses
Property types
- Sanitary and storm laterals
- Building drain sections
- Process lines (by arrangement)
Methods used
- CCTV inspection with located defects
- Condition classification: cracks, offsets, bellies, collapses
- Access and dimension checks needed for lining
Limitations, stated plainly
- Inspection reports evidence; lining suitability remains the contractor's and engineer's determination
- Heavily deformed or collapsed lines typically cannot be lined
What you receive
- Inspection footage and located findings
- A condition summary with lining-relevant observations
- Questions to put to any relining contractor
Next steps
- Require footage with any relining quote
- Compare lining and replacement against the evidence
- Re-inspect after works
