How to Fix a Crushed Culvert

Culverts are an important part of any roadway, as they allow water to flow beneath the road while protecting the underlying Infrastructure. However, when a culvert is crushed, it can cause a lot of damage to the surrounding area and be difficult to fix. In this blog post, we will discuss some steps on how to fix a crushed culvert.

If you’ve ever driven down a country road and seen a large metal pipe sticking up out of the ground, then you’ve seen a culvert. Culverts are used to divert water away from roads and bridges, and when they’re working correctly, they’re pretty invisible. Read on to know more!

How to Fix a Crushed Culvert

Summary: If you find yourself in the unfortunate position of having a crushed culvert, there are a few things you can do to fix the situation. First, check to see if anyone is trapped underneath. If so, remove them using caution and summon help. Next, clear the debris from the culvert and replace the damaged portion with a new one. Finally, seal the culvert off using a concrete or metal wall to prevent further damage.

12 Effective Ways on How to Fix a Crushed Culvert

1. Replacing a Smaller Culvert

If the culvert is simply crushed and you can see enough of it to visualize what it’s supposed to look like, you may be able to replace it with a smaller culvert. Although this will increase your initial expenses due to the cost of the material, using a smaller culvert will decrease future costs due to increased efficiency and decreased maintenance.

2. Lining a Culvert

If the culvert is only partially damaged, you may be able to fix it by lining it with rocks or gravel. However, this will not work as well if the culvert is very damaged.

3. Cleaning a Culvert

If there is no damage to the surrounding area, cleaning out a culvert may improve its function and decrease future costs. However, this option should only be chosen if you can repair any leaks or holes after the cleaning is complete.

4. Re-leveling a Culvert

If you level out the surrounding area to match the alignment of the culvert, this may allow for continued functionality at reduced costs associated with future repairs. In addition, this option will require the least amount of work to maintain in the future.

5. Replacing the Culvert Entirely

If no other options are available for repairing or improving your culvert, you may want to consider replacing it entirely. Generally, this option will provide the most long-term benefits and is preferable to older, outdated designs that can malfunction easily.

6. Nesting

Culverts can be stacked on top of each other when they are close together. This is often done in non-public areas, such as parks and hiking trails, where aesthetics aren’t much concern. Although this option will not help with the functionality of the culvert, it does reduce future costs associated with repairing or replacing it.

7. Mounting

If your culvert is made of a strong enough material, it may be possible to use bolts or clamps to mount the oversize product above ground. This option can reduce future costs associated with repairing or replacing your culvert but should only be considered if you are certain that the bolts, clamps, and mounting material will not be damaged or destroyed when the product is under stress (such as water flow in the rain).

8. Using a Plow

Using a plow to push material back around your culvert can sometimes level out dips and bumps created by traffic above it if you have the equipment available. This may not be the most efficient method, but it has been known to work in a pinch.

9. Dumping Dirt

One of the simplest ways to fix culverts is simply bringing in more dirt and dumping it around your structure. This is often an inexpensive way to do things, though you’ll need a truck or a good shovel.

10. Leveling the Damage

Use several pieces of wood and some quick-setting concrete to lift your pipe as much as possible before adding any more fill. This will help reduce the time it takes for water to flow through your system, which can help prevent further damage from being done if you have any leaks.

11. Lining the Damage

You can’t fill a tear or hole in a culvert, but you can fix them by lining the inside of your structure with a piece of rubberized polyester fabric. This will keep water from escaping and causing more damage to your system.

12. Creating a Plug

If you have a smaller hole, it’s possible to fix it with a piece of wood that you’ve drilled a hole into and then filled with quick-setting concrete. Of course, you’ll need the right type as well as something to keep the material from spilling out, but this can be useful if your problem is only one small hole.

Step by Step Process: How to Fix a Crushed Culvert

Step 1: Inspect the Damage

Before beginning any repair, take an inventory of all damages to your culvert. If possible, inspect the damage from inside and outside of the culvert. Then, roughly outline each damaged section and plan out how you will be repairing it.

Note: If you believe there is a possibility that any broken pieces may fall into the culvert, mark the hazard with cones or barricade tape.

Step 2: Prep Work

Before getting started, make sure there are no power lines nearby that may be damaged while digging. If your culvert is on public land, it’s best to call your local utility companies to ensure all underground lines have been marked before beginning any repairs. Move or remove any equipment that may be in your way and take note of the location of any underground wires.

Step 3: Mark Location of Damaged Area

Using a shovel and marker, mark out exactly where you will be working in the trench. To find the deepest part of your culvert, follow these steps:

  1. Locate the lowest point in your culvert.
  2. Mark this location with either a stake or cone to mark where you begin digging.
  3. If there are any bents (small sections of bridge), start marking at the highest point on each bent before tracing all the way down to the lowest point in your trench, following the flow of the water.

Step 4: Excavation

Using a shovel or excavating equipment, dig out the trench to expose the damaged area. If your culvert has been severely crushed and is more than 3 feet deep, it might be necessary to rent a track hoe from a local hardware store to remove large concrete sections.

Step 5: Cleaning the Pumping Chamber

Depending on the size of your culvert, it may be possible to reach inside and remove any debris that might be clogging up your pump. If this is not an option, you can use a pressure washer or wet/dry vacuum to clean out the chamber.

Step 6: Repairing the Damaged Area

Once ready, begin saving concrete repair material around damaged areas. Use a shovel or trowel to mix enough concrete repair material to fill the damaged area. Make sure you are filling in any gaps between broken pieces of the bridge before packing down each layer with your trowel.   

Step 7: Curing

Cover the repair area with plastic and place heavy objects on top to act as weights. Keep the area covered for at least 24 hours after completing your repair. This will allow time for the concrete mixture to cure fully.

Step 8: Clean Up

Once cured, remove all weights and plastic sheeting from your culvert. Next, remove any leftover concrete from your work area that was not used during the repair process. Now, you are ready to continue with your regular culvert damage and maintenance inspections!

Some Helpful Tips to Maintain Your Culvert

  1. Keep vegetation away from the culvert so it can operate smoothly.
  2. Maintain a proper culvert slope to allow sediment and excess water to flow through instead of building up around the structure.
  3. Inspect your culvert regularly for safety or signs of damage, such as broken or cracked pipes, gaps in joints or road base, etc.
  4. Install a waterproof membrane or a pre-cast concrete overflow to direct water around the culvert if it does not have an outlet for excess water.
  5. Erect barriers around your culvert to prevent excessive erosion and sediment from stopping the culvert from operating properly.
  6. Always watch for warning signs, such as cracks, seeping water, or other obstructions.
  7. Have a professional inspect your culvert from time to time to ensure safety and proper function.

Frequently Asked Questions

What Material Is Best For Culverts?

There is no one specific material that is best for culverts, as different situations call for different materials. For instance, if the culvert will be exposed to water and sunlight, then a weatherproof material like concrete or metal may be a better option. If the culvert will only be used during inclement weather conditions, then an asphalt-based product might be preferable. And finally, if the Culvert will only occasionally experience high winds or other forms of water exposure, rubberized plastic could work well.

What Is The Strongest Culvert Pipe?

There are many factors to consider when looking for the strongest culvert pipe, including stress ratings, material composition, and installation ease. Ultimately, the best option will depend on your specific needs and requirements. Some of the most popular culvert pipes include those made out of steel or concrete.

When it comes to STRESS RATINGS, these pipes should be able to handle a minimum loading capacity of 500 pounds per square inch (PSI). The more PSI that is supported by a pipe, the greater its ability to withstand pressure fluctuations during heavy rain or snowmelt events.

Concrete culvert pipes can also come with reinforcements such as rebar or wire mesh cast into the fabric during manufacturing. This helps in resisting buckling and distortion under load conditions. Additionally, all concrete culvert pipes undergo intense compression testing prior to shipping so that they are at their maximum strength.

As for MATERIAL COMPOSITION, Culvert Pipe manufacturers typically prefer materials that are lightweight yet durable. They also want tubes that resist corrosion and provide long-term performance in harsh weather conditions.

Can You Use A Plastic Culvert For A Driveway?

A plastic culvert can be used for a driveway in a limited capacity. However, it is not recommended for larger driveways as the plastic may not be able to handle the weight and pressure of a large vehicle. If you decide to use a plastic culvert for your driveway, make sure to consult with a professional prior to installation.

Which Foundation Is Suitable For A Culvert?

There are a few different types of foundations that are suitable for a culvert, and you will need to decide which one is best suited for the conditions where it will be used. If the foundation is designed to provide waterproofing and protection from erosion, then an asphalt or concrete foundation may be a better option. This type of foundation is often flexible and can withstand high-impact forces without collapsing.

If you need something that can resist water infiltration but doesn’t require extensive maintenance, then a rubberized foundation might work well. These foundations have been treated with chemicals that make them resistant to moisture absorption as well as oils and greases. They are also lightweight so they don’t add much weight to the structure above or below them.

Finally, if you just want something simple that provides basic support but isn’t weatherproof or durable, then a compacted soil base may be adequate.

Final Words

Culverts are a great alternative to bridges when crossing over an obstacle too much for a simple road or trail crossing. However, many of these culverts can become damaged by excessive sediment, water, and other elements. This is why it’s important to follow certain guidelines regarding culverts in your area.

Keep them clear of debris and other obstructions to operate smoothly, and inspect them regularly for damage or blockages. We hope this blog post on how to fix a crushed culvert has been helpful. If you have any questions or want to know more, then feel free to comment below!
