The problem on this Leander site
Two tenant suites had backed up three times in six weeks. The center stayed open through it, so any repair had to avoid trenching across the drive aisle during business hours. Nobody had a reliable as-built for the underground.
How our NASSCO-certified crew approached it
- Worked from the closest access point to keep equipment off the drive aisle during business hours
- Camera-inspected to the collapse, then sonde-located depth and alignment and marked the real line on the pavement
- Documented that the remaining run was sound enough for lining, which put trenchless on the table
- Coordinated the after-hours rehab window and re-scoped the finished liner
What the camera documented
- Fully collapsed section of clay pipe with soil intrusion blocking most of the flow path at 96 ft
- Root mass at two upstream joints feeding debris into the collapse
- Line depth and alignment mapped by sonde, showing the run sat 2 ft off the assumed as-built
- Remaining run structurally adequate for trenchless rehabilitation
Measurable results
- Accurate depth and alignment let the rehab contractor plan a cured-in-place liner instead of open-cut across the drive aisle
- Work staged after hours with no tenant closures and no lost parking during business hours
- Post-lining scope confirmed a continuous, seamless liner at full diameter
