A useful inspection records more than what is visible on the day of the visit. We document concrete condition, cracking, spalling, corrosion indicators, infiltration, coating or liner defects, joints, penetrations, and access limitations with photographs and organized field notes. WCCL also provides manhole vacuum testing, manhole joint testing, and sewer-line testing to help verify structure and line performance, identify potential infiltration or leakage, and support rehabilitation decisions. This information helps owners and engineers prioritize repairs, compare alternatives, and plan work around operating constraints.
