Culvert Cleaning

Ensuring stormwater flows freely and safely

Blocked culverts can cause serious flooding and infrastructure damage. Regular cleaning protects property, maintains road safety and ensures compliance with environmental regulations.

Our crews use high-pressure water jetting and vacuum units to remove silt, vegetation and debris from culverts of all sizes. We respond quickly to storm events and can integrate culvert cleaning into routine maintenance programs.
