What Is A Culvert?
A culvert is an artificial road or stream structure designed to allow water to pass underneath a road or railroad tracks. They are usually made with concrete, steel, fiberglass, or other materials. A culvert can be made of different materials, but they all have the same purpose: to redirect water in an arched or tubular structure. Culverts are used to keep streams and rivers from overflowing during heavy rainfall. They also prevent the stream from eroding the ground around it and protect homes and businesses near these water bodies. Culverts come in a variety of shapes and sizes depending on the size of the road and the waterway below it. There are many different types of culverts that you can use for your project. The kind of culvert you use will depend on the size of the road and the waterway beneath it.
Slab Culverts

A slab culvert is the most common type of culvert. It is normally used on smaller roads or waterways. A slab culvert is made from concrete and features a flat base. A slab culvert can be made with removable panels in order to make repairs easier. A slab culvert is ideal for waterways with a maximum flow of about 500 cubic feet per second. If the culvert is used for a road, it’s recommended that the flow be less than 10,000 vehicles per day. The concrete used in a slab culvert is 4 to 6 inches thick. It’s also common to see slab culverts constructed from asphalt.
Box Culverts
A box culvert is similar to a slab culvert but features a rectangular arched roof. Box culverts can be precasted and this allows more control over the quality of the concrete. This also reduces the time spent in situ. Box culverts are often made with removable panels for easy repairs. A box culvert is ideal for waterways with a maximum flow of about 2,000 cubic feet per second. If the culvert is used for a road, it’s recommended that the flow be less than 10,000 vehicles per day. The concrete used in a box culvert is 3 to 4 inches thick. These culverts are commonly used for medium-sized waterways and are mainly constructed where the soil is soft and the load has to be distributed over a wider foundation area.
Round Culverts
A round culvert is a type of culvert that features a circular shape. Round culverts are commonly used for larger streams or rivers. Round culverts can be constructed with concrete, wooden staves, or polystyrene. A round culvert is ideal for waterways with a maximum flow of about 8,000 cubic feet per second. If the culvert is used for a road, it’s recommended that the flow be less than 10,000 vehicles per day. The concrete used in a round culvert is 4 to 6 inches thick.
Concrete V-Shaped Culverts
A concrete v-shaped culvert is a special type of round culvert. A v-shaped culvert is used for large streams or rivers. A v-shaped culvert is ideal for waterways with a flow of about 20,000 cubic feet per second. If the culvert is used for a road, it’s recommended that the flow be less than 10,000 vehicles per day. The concrete used in a v-shaped culvert is 4 to 6 inches thick. V-shaped culverts are also commonly made from wood.
When To Use Each Type Of Culvert
Start by measuring the width of the road or stream to determine the right size culvert. The diameter of the culvert should be at least 36% wider than the stream. This will ensure a good seal.
For a road:
- The culvert diameter should be the same width as the road.
- The culvert depth should be at least 36% wider than the width of the road. For a stream:
- The culvert diameter should be at least 36% wider than the stream.
- The culvert depth should be twice as deep as the width of the stream.
For a river:
- The culvert diameter should be at least 36% wider than the river.
- The culvert depth should be 2 to 3 times as deep as the river's width.
