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 and replace them, and then repair any property disruption or damage. But what if you had a fast, easy process available for rehabilitating your municipality's or agency's old culverts? 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, then creating a water-tight seal at the edges. Because the new liner slides into place, and the old culvert is not removed, slip lining requires very little digging or excavation. Typically, slip liners are made of 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 is placed, 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's a good solution for culverts which may not be completely round anymore, whether due to corrosion, soil settlement or heavy surface loads. This gives 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 - something that can easily happen with metal culverts. The slip liner is 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.
