When camera inspection identifies a single joint failure, localized crack, or isolated collapse in an otherwise serviceable storm drain system, full-run CIPP lining is over-specified. LiningWorks spot repair installs a targeted trenchless liner only at the confirmed failure location — addressing the defect without the cost of full-run rehabilitation.
Free phone consultation. Flat-rate pricing. No upsells, ever.
Full-run CIPP lining is the right solution when defects are distributed across the pipe run — widespread joint failure, extensive corrosion, or multiple collapse sections. Spot repair is the right solution when camera inspection confirms that defects are isolated to one or two locations in an otherwise intact system.
Spot repair uses a short-section CIPP liner (typically 3–10 feet) installed only at the confirmed defect location — achieving the same structural rehabilitation as full-run lining at a fraction of the material and installation cost.
LiningWorks camera-first assessment determines whether the defect distribution calls for spot repair or full-run lining — ensuring the right scope is recommended for the actual pipe conditions.
Schedule a Storm Drain Assessment
Watch how a trenchless spot liner is positioned at a specific defect location and cured to provide complete structural rehabilitation of the targeted failure section.
Spot repair is the appropriate scope when camera inspection confirms that pipe failures are isolated rather than distributed — and when the surrounding pipe is structurally intact.
Storm drain spot repair follows the same camera-first process as full-run lining — with liner installation targeted precisely at the confirmed defect location.
A Winston-Salem industrial park's post-storm flooding investigation found a partial crown collapse at a single location in an otherwise serviceable 18-inch RCP storm drain main. The surrounding pipe was in good structural condition — full-run CIPP lining was not warranted.
LiningWorks installed a 6-foot structural spot liner spanning the collapse location with 2-foot overlap on each side. Post-installation camera confirmed full liner bond and complete coverage of the collapsed section. The full pipe run was returned to service the same day as spot liner installation.
“Found a partial crown collapse in one section of an otherwise good pipe. LiningWorks recommended a spot liner rather than lining the whole run — installed it the same day camera confirmed the scope. Correct call and fraction of the full-run cost.”
Camera-first assessment means LiningWorks recommends spot repair when camera confirms the defect is isolated — not full-run lining when it isn't warranted.
Camera confirms the defect — spot liner addresses it without over-specifying the rehabilitation scope.
336-477-3218, Mon–Sat 7AM–6PM. Flooding, surface depressions, recurring blockage at a specific location — describe the symptoms and we'll schedule the right camera assessment.
We scope the affected run to determine defect distribution — confirming whether spot repair is appropriate or whether full-run lining is indicated by widespread defect distribution.
Targeted spot liner installed through existing access, cured to full structural specification. Post-installation camera confirms position and bond. Same-day return to service in most cases.
