Storm drain CIPP lining rehabilitates deteriorated pipes from the inside — no excavation required.

WHAT IT DOES

How CIPP lining rehabilitates storm drain pipe systems.

Storm drain CIPP lining works the same way as sanitary sewer CIPP — a resin-saturated felt liner is inverted into the pipe through an existing access point, then cured to form a rigid, structural pipe within the deteriorated host pipe.

For storm drain applications, liner specification accounts for the hydraulic demands of storm drain systems — including higher peak flow velocities, larger pipe diameters, and the structural loading from roads and parking areas above the pipe.

Post-installation CCTV camera inspection verifies the full liner run — confirming bond, joint coverage, and absence of voids before the project is closed out and the site is returned to full operation.

PIPE TYPES SERVED

Storm drain materials and conditions where CIPP lining applies.

Storm drain CIPP lining applies across the pipe materials and deterioration conditions most commonly found in commercial and municipal storm drain infrastructure.

• Reinforced concrete pipe (RCP) with joint separation or corrosion

  RCP storm drain infrastructure deteriorates through joint separation from differential settlement and H2S corrosion in systems receiving organically contaminated runoff. CIPP lining seals joints and restores structural integrity.
• Corrugated metal pipe (CMP) with invert corrosion and wall thinning

  CMP culverts and storm drain systems corrode from the inside — losing wall thickness progressively. CIPP lining installs inside the corrugated profile, restoring structural capacity and providing a smooth hydraulic interior.
• Concrete box culverts with crack and joint deterioration

  Concrete box culverts develop longitudinal cracks from beam loading and joint separation from differential settlement. CIPP panel lining can rehabilitate box culvert structures in many configurations.
• Clay and vitrified clay pipe in older commercial storm drain systems

  VCP was used in storm drain applications in older commercial and residential developments. These systems age through the same joint failure patterns as sanitary sewer VCP.

BEFORE & AFTER

Shopping center parking lot — 300-foot RCP storm drain rehabilitated without pavement disruption.

A Charlotte shopping center's main parking lot storm drain had developed joint separation at multiple locations, confirmed by camera inspection showing active water infiltration and void formation at three joint locations. Two surface depressions in the parking lot surface had been monitored for over a year.

LiningWorks installed a CIPP liner through the full 300-foot RCP run through existing curb-inlet and manhole access. Post-installation camera confirmed full liner bond at all three previously identified joint locations. The parking lot surface was not disturbed during the rehabilitation. Post-installation CCTV showed complete elimination of all visible joint gaps.
