Culvert Repair

What This Service Involves

We repair corroded, crushed, separated, and undermined culverts using methods ranging from joint sealing and invert paving to trenchless lining and full replacement. Deteriorating culverts threaten roadway stability across Western Washington, where saturated soils and heavy flows exploit any structural weakness. Our crews restore the pipe's hydraulic function and structural capacity while protecting the embankment and, where applicable, maintaining or improving fish passage. Repairs are documented with methods, materials, and as-built conditions for your infrastructure records.

Benefits

Restores structural and hydraulic function to failing culverts; protects roadway embankments from collapse and washout; offers trenchless options that limit road closure and excavation; maintains or improves fish passage where required; documents methods and as-builts for asset management

Our Process

1) Inspect and assess the failure mode and repair options; 2) Select the method and secure permits and traffic or in-water controls; 3) Rehabilitate or replace the culvert to specified standards; 4) Restore embankment and surface, then record the completed work

What Affects the Cost

Culvert size, material, and failure severity; repair method from lining to full replacement; embankment and roadway restoration extent; permitting and fish-passage requirements; traffic control and detour needs

Best Time of Year

Culvert repairs are scheduled in the dry summer season to work within fish windows and complete embankment restoration before wet-season flows return.
