Do Relined Pipes Reduce Flow: How It Works
The Short Answer
- CIPP relining creates a new structural pipe inside the damaged one
- Installed through existing access points — no excavation
- Design life of up to 50 years, jointless against roots
- Priced per metre after a CCTV assessment
- Suitable for clay, fibre-cement, cast iron, concrete, uPVC and HDPE
The Honest Caveats
- Fully collapsed pipes cannot be relined — no open bore, no liner
- Severe deformation beyond roughly 30% ovality needs another method
- Grossly undersized pipes should be upsized, not relined
- The CCTV survey settles it — you see the evidence before deciding
- We recommend excavation when it is genuinely the better option
Every answer starts with a CCTV survey: recorded evidence, exact measurements, and a per-metre quote you can compare with confidence. Serving Johannesburg, Pretoria, Centurion, Midrand, Sandton, the East Rand and West Rand — with teams reaching Mpumalanga, Limpopo and North West.
How It Works
1. CCTV Survey
We inspect the line on camera, measure the damage and confirm the pipe is suitable for relining.
2. Clean & Prep
High-pressure jetting and root cutting restore the full bore before any liner goes in.
3. Line & Cure
The resin liner is installed through existing access points and cured into a hard, jointless pipe.
4. Verify & Warranty
Post-cure CCTV footage, written report and warranty documentation handed over.

Do Relined Pipes Reduce Flow FAQ
How much does do relined pipes reduce flow cost?
Typical 2026 South African ranges: R1,500–R3,500 per metre for residential relining (110 mm) and R3,000–R8,000+ per metre for larger commercial diameters, with call-out/CCTV assessment from R1,500–R4,000. Diameter, length, access and connections determine the exact rate — confirmed from the recorded CCTV footage before you approve anything.
How long does the work take?
Most single lines are cleaned, lined and cured in 1–2 days. Larger or multi-section jobs are scoped from the CCTV survey and scheduled around your operating hours.
Is the result as strong as a new pipe?
Yes — the cured liner is a structural pipe in its own right with a design life of up to 50 years, and the jointless bore stops roots permanently.
Do you provide proof of the repair?
Every job ends with post-cure CCTV verification footage, a written report and warranty documentation — evidence you can hand to an insurer, trustee or buyer.
