When your culverts are aging or beginning to fail, rehabbing them can seem like a difficult, expensive process. You need to dig up old culverts, remove them, replace them and then fix anything that has been disrupted at the end. But what if rehabilitating your municipality's or agency's old culverts could be done in a fast, easy fashion? Slip lining provides you with an easier, less labor-intensive way to rehabilitate your aging culverts without any significant digging, dangerous trench operations or risk of failure. Here are some of the benefits you can expect to see when slip lining your old culverts.
When you're slip lining a culvert, the process involves sliding a new section of HDPE slip liner into your existing culverts and then sealing it at the edges to ensure a water-tight seal. Because the new liner slides into place and the old culvert is not removed, it's a system that requires very little in terms of digging. The liner used for the slip lining process is typically HDPE, which has a long expected service life. In fact, it's often longer than that of concrete or steel used for the original culverts. It also has exceptional strength, making it a great choice for your culvert rehab project.
Once the slip lining has been put in place, the void between the existing culvert and the new slip liner layer is filled, typically with a waterproof grout, to seal the annular void. Because the HDPE is somewhat flexible during installation, it works well when your culverts may not be completely round anymore, whether due to corrosion, soil settlement or heavy surface loads, giving your crew flexibility in the field. The slip liner is strong, providing structural support to the culvert and the land above it. Because the surfaces are plastic, there's no worry about chemical exposure or corrosion becoming a problem down the road as often happens with metal culverts. It's a mechanically durable substance, with HDPE being very resistant to impacts and fatigue, expected to last 50-100 years or more in accelerated laboratory testing conditions.
