Surface flooding and overflowing manholes during storm events indicate a storm drain system that has lost design capacity — through sediment accumulation, structural obstruction, or pipe failure that restricts flow below design levels. Restoring capacity through trenchless rehabilitation prevents property damage, liability exposure, and regulatory violation.

Commercial storm drain systems lose capacity through specific mechanisms — each identifiable by camera inspection and addressable through targeted trenchless rehabilitation.
Surface flooding from storm drain systems has different causes with different solutions — camera inspection identifies which mechanism is causing the capacity loss before any rehabilitation scope is developed.
Surface flooding from failed storm drain systems affects commercial properties with high impervious coverage, aging drainage infrastructure, and properties in low-lying areas near natural drainage pathways.
A Charlotte retail strip center had experienced parking lot flooding during moderate storm events for three consecutive seasons — always in the same low-area near the main storm drain run. Camera inspection found significant sediment accumulation throughout and a partial crown collapse at one section approximately 40 feet from the main inlet.
LiningWorks hydro-jetted the full storm drain run to clear sediment accumulation, then installed a CIPP liner through the collapsed section. Post-installation camera confirmed full sediment removal and liner bond at the collapse location. No flooding has occurred since rehabilitation through multiple storm events.
“Parking lot flooding every time it rained hard for three seasons. Camera found sediment everywhere and a partial collapse 40 feet from the inlet. LiningWorks jetted the full system and lined the collapse in one mobilization. Zero flooding events through an entire hurricane season since.”

Storm drain capacity restoration requires accurate diagnosis before rehabilitation scope development. LiningWorks camera inspection identifies whether the problem is structural, sediment, or capacity-related before recommending any work.
Camera assessment identifies the cause — then we address it in a single mobilization where possible.
336-477-3218, Mon–Sat 7AM–6PM. Where the water ponds, how quickly during storm events, whether it's recurring — describe the flooding pattern and we'll schedule the right camera assessment.
We scope the affected storm drain system to identify sediment accumulation, structural failure, and flow restrictions — then develop a combined rehabilitation scope to restore design capacity.
Hydro jetting clears sediment and CIPP lining addresses structural defects — both performed through existing access points. Post-installation camera confirms capacity restoration.
