What Are The Biggest Problems with Culvert Replacement?


A culvert is a small, tunnel-like structure that serves as a passageway for water to flow under driveways, railroads and public roads. During the winter and spring seasons, it’s of utmost importance that culverts remain functional in order to prevent huge mishaps from happening. Whether for commercial applications or residential projects, professional culvert replacements should be done by qualified technicians to obtain the best results.

Here are some of the biggest culvert replacement issues that technicians could face at any point during the process:

Common Culvert Issues

Culverts are susceptible to damage from the changing of seasons, i.e., corrosion, frost, time, etc. and when they are not functioning 100%, then it’s time for a replacement. When left unchecked, culverts can lead to significant road and pavement damage, thereby reducing its overall lifespan. The formation of ice can block the culvert and prevent any draining from happening when the snow melts.

Post-winter season, sand and gravel can accumulate inside culverts and over time, these can cause the water to flow on the road surface and cause all kinds of road safety issues. It could also wash out the road and cause erosion faster. The inlet of a culvert acts as a drain and is susceptible to the same problems a drain may face- leaves, dirt, gravel and man-made waste products will eventually block it and make it unable to function efficiently.


Culvert Maintenance and Replacement

Road culvert maintenance is somewhat of a common issue because the first thing that needs to be done in a culvert inspection is to locate the culvert itself. Sometimes a culvert can be modified in order to create a bridge that could transport traffic from one side to the other. The many sizes and possible shapes a culvert can assume are the following: box-like, flat-bottomed, elliptical and round constructions.

The nature of culvert replacement itself is tedious, time-consuming and requires a lot of labor to get done. Incorrect culvert sizing and initial installations often dictate how easy or how hard the replacement will be. A culvert could be positioned too high or end up that way because of eventual road settling, and this could result in over-accumulation of water in approach ditches and siltation at the ditches’ bottom. There are instances where culvert is missing where it should have been installed. The solution? provide a new one.

The diameter of an access road culvert is usually smaller than main road culverts, and for this reason blockages and clogs happen more frequently. The low water flow leads to more materials being lodged in, making it more susceptible to blockages. Having a shorter length than necessary also leads to a clog. In these cases, a new culvert having a longer length can replace the existing one.

Special drainage structures can overcome culvert challenges, no matter how small or large the project is. The best solution is to install main road culverts using the latest technology and the best possible materials available.
