CMP culvert rehabilitation
Corrugated metal pipe commonly fails from invert corrosion, rust-through, and joint separation. A smooth-bore HDPE culvert liner restores the waterway while avoiding full replacement.
Culvert Liner Product Overview
Culvert Renew® is a purpose-built HDPE culvert liner for culvert relining, culvert slip lining, and trenchless rehabilitation. When an existing culvert can stay in place, owners can restore service with a smooth-bore plastic culvert liner instead of excavating the road or embankment above. If the project team is still screening options, use the reline-vs-replace guide and the full culvert liner FAQ.
Why owners search for a culvert liner
Liner-intent projects usually already have a culvert in the ground. The question is whether that host pipe can be renewed from the inside instead of removed. Culvert Renew® is built for that decision point: HDPE culvert liner sections are assembled with the Thread-Loc® joint, inserted through the host pipe, and grouted in place to restore the line with limited surface disruption. For the material-first evaluation path, use the dedicated HDPE culvert liner page.
- HDPE culvert liner material resists corrosion, abrasion, and aggressive stormwater exposure.
- Smooth-bore hydraulics often recover or improve flow compared with rough or damaged host pipe.
- Closed-profile construction and grouted annulus support long-term culvert rehabilitation performance.
Where this culvert liner fits best
RCP and storm drain relining
Reinforced concrete and urban storm drain systems often need trenchless renewal where excavation would affect traffic, utilities, or developed property.
Deep-fill and high-disruption crossings
Slip-lining is especially valuable under highways, rail embankments, and other crossings where open trench work would be expensive or operationally disruptive.

What is a culvert liner?
A culvert liner is a new pipe installed inside an existing culvert to restore structural integrity and flow without excavating the roadway above. Culvert Renew® is an HDPE culvert liner designed for slip-lining and trenchless culvert rehabilitation.
When is an HDPE culvert liner preferred over replacement?
An HDPE culvert liner is preferred when the host culvert is still passable, alignment can remain in place, and the project needs to avoid excavation, traffic disruption, surface restoration, or rail interruption.
Can a plastic culvert liner be used for storm drain rehabilitation?
Yes. A plastic culvert liner is often a strong fit for storm drain rehabilitation because it restores corroded or joint-separated drainage lines with limited surface disruption and improved corrosion resistance.
